    Solubility Products, Common Ion Effect, Hardness of Water: Discussion, Conclusion, Safety Notes


    Discussion
                In general, springily soluble with math formula of LeChatelier’s principle has been useful on salt solubles. A low soluble can be a dynamically equilibrium so its concentration on its ion is low.
                Express BaSO4 in math formula on LeChatelier’s Principle has main compunds the Barium and Sulfate

    BaSO4 (s)  º  Ba+2(aq)  + SO4-2 (aq)


    The equilibrium expression for this reaction is:


     Since in a heterogeneous equilibrium the concentration of solid BaSO4 is a constant
    for a given temperature, we can rewrite the expression as:


    Ksp is called the solubility product constant.

                Many other has been issue on how soluble can be a sparingly soluble by modern gadget and equipment used. The solution is  Ca(OH)2 and the result is about small so its called sparingly soluble. Data shows how this happened and implies on mixing some concentration like NH3-NH4Cl solution in order to give better analysis on experiment. It solution can be determine the moles and its concentration calculations.  This data has substance of one mole Ca+2 and 2 moles OH-1 are present in solution.

    The experiment also gives an idea of pertaining to the ph of substance that can be use if the solution is acidic or base. Some measurement as added like filtration paper in which some of its property like color has been change. PH indicator is good for detection how much acidic and base of substance is. This PH indicator for the measurement of [OH-1] in which it’s precisely measurement also th Ksp and the molar solubility. Ions have been added to solution to predict the molar solubility of said substances.

    Conclusion

    Hereby, this experiment has result, based on this the common ion was reduces the soluility of Sparingly Soluble Salt. We have 0.012 vs. 0.013. This agrees with LeChatelier’s principle.

    Safety notes

    On lab, always be ready for things, pls wear gloves cause substance can be irate skin, protect the eye, wear lab coat and be careful on chemical used. Don’t direct inhale near on experiment instead use mask for protection on do inhale and exhale near on experiment of chemistry. And be careful with indicator.

    Thermodynamic Concert with Semiconductor.

    Thermodynamics or also know the study of energy forms that relate to physical science is useful on industries, country and this now said modern times.
    Upon applied science, successful inventions are getting forward on a chemical reaction system that operates engines that relate to thermodynamics.
    Chemical Kinetics or called reaction kinetics is a study of a rate of the chemical reaction by experimental by usually use if chemical reactors. <wikipedia.com>
    The simplest type of reactor is a batch reactor. The material is loaded into the batch reactor and the reaction is allowed to continue over time. Discontinuous reactors do not reach the steady-state and often require temperature, pressure and volume control. Therefore, many discontinuous reactors have ports for sensors and inputs and outputs of materials. One example of a batch reactor is a pressure reactor.
    This has a fluid reagent that stirred into a tank reactor by impeller for removing the effluent from a reactor. Division of volume of the tank by the average volumetric flow rate the tank over time that essential for a process on reactor fluid.
    This reactor has a pump or tube that used for a pump a one or more fluid reagent. As the reagent passes through the PFR, the chemical reaction continues. In this type of reactor, the changing reaction rate produces a gradient with respect to the displacement distance. At PFR input, the speed is very fast, but as the product concentration increases, the reagent concentration decreases and the reaction rate decreases.
    Semi-continuous reactors operate on continuous and batch inputs and outputs. For example, fermenters contain a medium that must be continuously removed and a stream of carbon dioxide that produces microorganisms.
    Also implemented as plug flow reactors but a more complex process. The rate of the catalytic reaction is proportional to the amount of catalyst in contact with the reagent and the concentration of the reactants. Solid phase catalysts and liquid phase reactants are used which are directly proportional to the diffusion area of the reactants and products, the diffusion efficiency of the reactants and the efficiency of the mixture.
    An ideal model does not mean axial mixing. Each liquid element passing through the reactor does not mix with the upstream or downstream liquid, as the term "component flow" implies.
    Another thing to do is the reagent that placed within the reactor than the inlet that makes greater efficiency or low cost of the bar.
    For efficiency, it has greater than a jacket of similar size. Also on speed percentage on jacket bar and not true for reversible feedback.
    This is not 100% reaction complete, it has to do with a point on a dynamic equilibrium where reaction rate decrease.
    Plug Flow Reactor use on the field of gas and liquid phase system for the use of it on gasoline production, oil crackling, synthesis of ammonia from that element and oxidation of sulfur dioxide to sulfur dioxide.

    Good Coding Practices for Software developers

         Developers and most of them are on the right track that has a good result. In fact, in the behind of this prototypes, there is common no errors during the process of coding. This could be avoidable and be commonly used for a recheck and recognize it.
          There could be an action of 3 bad coding practices: the misalignment of code, also not put some comment on source code and make some typos errors.
          Would be good to have commented on the code in order to recognize more what that particular function does? Yes, the comment is a good habit of coding practices. Moreover, there is now IDE- Integrated Development Environment that can check the misalignment of code and typos errors.

     Being an analyst trainee, it is the first time encountered such algorithm that enhances coding skill. A worrying thing happened during on work time has been made, and that why be thankful for stuff that helped to solve some coding problems. There are some c programming exercises that encountered during that training. After all, the majority of problems depends on how virus embedded in PE header file and how it is being treated for the reverse engineering process. Due to the technical solution, there might be a solution, thanks to coworkers.
         Such an application is a need for its configuration, some step can check how its work.
    Step 1.     It's quality and requirements
         Due to many designs of the product, it is important how this product's performance, set an expectation what would it is quality.
    Step 2.     Check what it's a platform
         Many software packages have been modified for each platform. This suit its functionality.
    Step 3.     Use the platform and also sharing is good.
         This includes the code quality of an application. Github is good for sharing information about software codes. And, JIRA is the most commonly used tool for bug tracking



         Being a developer consultant (on online), that was a heck of analyzing codes of c++. Some are not been made on time, however, thanks to the developer Zohar Mozafi he considered the time at true skills.  This had an exercise of c/c++ programming language. Some of the time to analyze is to get information on the internet. Many developers have encountered such as this.

    10 Important Things on Communication and Mass Media


    1.             The definition of mass media is how the information is sent to many people and this answer is intended by using technology. Mass media can be a source of music, show or current issues like news so that mass audience stays update on these issues by knowing the detail that has been in form of newspapers, radio, internet, television, and magazines. Now the platform like the internet is more convenience than past time because of new technology in recent times. Upon this modern technology, mass media influence the public opinion which it possible to the public to view the events through TV and other video capturing device. On TV, a lot of commercials has been broadcast with lavish design and wonderful sound on a product that makes consumer behavior change and could buy those things. This mass media helps on innovating the industry to have more trends powerful economic.

    2.    About process of information is referred to communication. There are components of sender-receiver model and this is:

    ·         Context- an idea makes its effective throughout communication also include aspects like an example of on a country that has unique communication from its own perspective.

    ·         Sender/Encoder – one who sends a message is called encoder who put an idea into spoken language, for instance, a sender who sends a message in understandable to a receiver. The encoder uses also symbols, graphs to get good respond.

    ·          Message- This is the information between sender and receiver that conveys an idea, for example, the point of the message is clear and concise.

    ·          Medium- It is the channel between the sender and receiver. For instance,  a sender sends message to a receiver  through a message, print, electronics, or speech which has sound.

    ·         Receiver/Decoder – a person who receive or recipient of a message. For instance, a person might receive an opinion.

    ·         Feedback – A response on receiver upon taking the message. For instance, feedback is an important role in business that enhances more products due to a feedback of consumers.

    3.              Three forms of media, which are print, broadcast and digital. The print is the oldest form of media. Print includes newspaper, magazines. It's something to do with readership material that has facts like in news. A broadcast is a form of media that has embedded with a technology of television or radio, the audience listens to the information sent by this media and more of audience relies on a broadcast. Digital is the newest form of media, it comprises electronics device that can transmit a message like a readership, watch and listen form. It likes to be an internet based and some is stored info on an electronics device.

              For the technology become advance, audience interest on it that’s why many gadgets are now used for convenience and easier communication that people easily adapt to this technology. This gadget is now used and channel moved to modern class. 

    4.             Mass media are considered profit centered. A lot of information is entertainment and lot of own of broadcast has a large products of large company which the number of medium like newspaper declined due to modern technology as it can be put in business so that the business ownership could use large scale of mass medium and called conglomerate that own media companies like Sony have own media called Micronics. This affects book industry because of modern gadget wide use for business.

    5.              Many pop and culture are in form in music, dance, and classify as rock music and roll. Use of media can be enhancing its performance in build recognition on reconciliation to its own culture. The best medium for affecting culture is modern build technology. This is gadget filled with modern technology.

    6.              The modern medium has much functionality and it has a friendlier user. Unlike to past time it looks like its evolve into modernized platform but books as medium has unique characteristics, it has to be handily and good to read on eyes, it has own purpose and unique subject and can be used by student on school for learning and it is said to be good for children for learning process and it has lavishly design and this is how book adapted over time.

    7.              A newspaper is important to the public and it has been part of our daily like for several centuries. It’s kind of medium that are occurring around the world for inform of important events. It has been used by ancient Rome by carved the information on stone and over centuries the changed happened that newspaper is on paper by a printing press in the Unites States and through the world. Today it’s adapted also through modern gadget like a newspaper on the internet.

    8.              The medium like visual video, sound, and other media outlet are combined and merge in one platform can be embedded on media are called Media convergence. Media convergence allows multiple media in one platform. For example, the live streaming on YouTube and the other is the comprehensive website with many multimedia on it.

    9.              Importance of mass media is essential to our daily lives and through modern technologies, mass media is always getting used to on it even print is important for nowadays. The book can be used for educational purposes. Electronics media is also a new form of media that can be useful for business and economy in which the modern media is abode also on modern technology as a message is more explained and concise in a different form.

    10.                 The film is one of the oldest medium used on humanity. The oldest is known on Chinese (painting) about 400BCE. The first motion film in the US is about 1878 AD. On the 19th century, the film has enhanced its brightness and color. The 20th-century film is now on cinema run by modern technologies. On recent time, there is a digital film. The film is important that why it remain as one of mass medium because it gives human to have the ability to connect human experiences, and in social activity.

    Chemical Process Briefly Explained

         
       The batch process is a kind of chemical reactor that processed by a vessel in various operation in industries such as mixing of product, crystallization, polymerization, chemical reaction, solids dissolution.  This involves some structures like the body of the boiler, the agitator, and devices such as heat transfer, its transmission and the seal of a road.  Moreover, its feature generates it one is to one input to an output of materials that put and out on the reactor with efficient heat transfer, temperature and has flexible control, operate in reaction condition. There are some cases that its application needs a gas other than oxygen that fused on the inlet on the batch reactor liquids. This could be called aerators.

       Batch reactors are a generic term for the type of vessel widely used in the process industry. The name is an inappropriate name because this type of container is used for several process operations such as solvent dissolution, product mixing, chemical reaction, batch washing, crystallization, liquid / liquid extraction. The polymerization. In some cases, they are not called reactors, but they have names that indicate the role they play (as in crystallizers or bioreactors).
    The principle of turbine flow meters has something to do with pipes, blades, and rotor. The rate of flow in pipes has been flowing on pipes via a rotor that spins and this flow has passed on its blades and the thing on this measurement is called turbine flow meter. Mathematically, the rotational speed of the rotor in pipes is a direct function of flow rate and its sensed by magnetic pick-up, photoelectric cell or gears.

         There are volumetric turbine flow meter and velocity turbine flow. These are basic classification types of this flow meter and have different units, mL/min for volumetric turbine flow and ft./sec for velocity turbine flow. Classification of Volumetric turbine flow can be in a state of gas or liquid and can be-be critical need for measurement in many industrial plants so that it has an accurate flow of measurement, for business to have gain profit on this operation in industries. Inaccurate measurement can result in distrust of people in their company. So as of be carefulness, there are important parameters to consider when specifying turbine flow meters include velocity flow rate range, liquid volumetric flow rate, operating pressure, fluid temperature, material density, and material viscosity in order to have met its accuracy. On the other types, the velocity flow applies sensor. rate range applies only to those turbine flow meters that are velocity flow sensors or meters. 

         Importance of this can be maximized its accuracy, include the parameter of pressure. Viscosity is an important role for this that make include on a process on turbine flow measurement. It’s dependable on materials needed that the turbine can be stand or withstand like in turbine exposure at some temperature. In relation to viscosity, the higher viscosity, the higher pressure drops, or lower viscosity the lower pressure drops so selection material must be considered as used. Also, the pipe diameter is important to use.

    Cloud Computing Briefly Explained

         Unlike previous times, today's technology is very rich and sophisticated. The machine can now switch to the touch screen as a touch pad. The control panel has award-winning visualization data to ensure creative productivity in market competition. Use graphics to improve it and make navigating easier.

    Cloud computing and its some applications

       Technology today is very enhancing and high, unlike the previous time.  A machine can now navigate on display of touch like a touchPad.  A dashboard has a winning display data, and it ensures creative productive on the market competition. Enhance this using graphs, and easy to navigate.

       One of the uses of cloud computing for email is retrieving and storing data and these are fast. That's why it relates to storing and even no individual hard drive is needed for sorting files. Here are examples of a company that offers Cloud Computing: Google Drive, as an experienced end user, Google offers storage like Microsoft Excel that can retrieve and store on the internet. This is called the Google sheet. Apple iCloud, Same for synchronization of email contacts, the calendar and etc. Amazon Cloud Drive, this about synchronization of music, hybrid synchronization for both file and music with time and Cloud Hardware, like Chromebook that is fully cloud-centric. Their application is about using the operating system that can synchronize every file, data like apps from a web browser to OS, and vice-versa. For much additional information about these visit to See at Their frequency and question asked and Their website online.

       For convenience, cloud computing is important to businessman and end users.  For play a role in managing the payroll system, the data is protected, the important files even not store in their memory card but on the internet as an intangible thing. For business, it raises Their income, as noted in an Economy, the demand, and supply law, when the demand is high then the price is high too but lowers the resource, the internet has not limited in one-thing, so the income is high for the businessman.
     In market strategies, the elasticity will measure up, it Serves as the demand basis scale.  it is possible to make a business about cloud for some study reasons. It can be in open public. For security, it should be in private.

    Definition

       As definition, cloud computing is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

       Cloud computing is a type of computing that relies on shared computing resources rather than processing applications using local servers or personal devices.

       In the simplest case, cloud computing uses services ("cloud services") and moves them to the firewall of the organization. Applications, storage and other services are accessed through the web. Services are delivered and used through the Internet and paid by cloud customers according to the business model or payment for use as needed.
