Chemical process

Discussion Assignment Discussion Question 1 What is the difference between biochemical reactions in healthcare? Biochemical reactions occur as a chemical reaction, which naturally takes place in a living organism. It happens within a cell involving a catabolic reaction (breaking down of molecules) or a anabolic reaction (building up of molecules). The process involves a diversity of biomolecules interacting with one another in order to make up a new biochemical for a particular use in the body.…

A glow stick is a small plastic tube with chemicals inside it. When When you snap a glow stick and hear it crack it gives off a temporary glow. As you snap the glow stick and hear it crack. Chemicals inside the glow sticks starts to mix together. This is a process call chemiluminescence. Chemiluminescence is a process where light is produced by a chemical reaction. Instead of using an electrical source. An example of this would be if go outside during a fall night and see a firefly glowing…

The sand then will go through the process of filtration leaving salt water and sand separated. Then allow the salt water to evaporate where the salt will not evaporate and allow the salt to be separated from the sand. Page 52 20. Compounds can be broken down into simpler substances while elements cannot. 21. The composition of a substance is always fixed, but the composition of a mixture can vary. 22. Chemical symbols are used to represent elements and chemical formulas are used to represent…

The tarnishing of silver is due to a chemical reaction between silver and hydrogen sulfide, producing silver sulfide and hydrogen gas. The balanced chemical equation is 2Ag (s) + H2S (g) → Ag2S (s) + H2. This is a single replacement reaction. This reaction most commonly occurs through contact with hydrogen sulfide in the air - although direct contact with substances that contain sulfur can cause tarnishing. Silver tarnishes very quickly when it is exposed to air that contains high levels of…

Ans Decision tree analysis will involve step determination of the chemical and physical characteristics of this chemical. By knowing them, it will be very easy to determine the best control method to be employed. Firstly, the compound is corrosive and it therefore suggests that it is highly reactive and use of water and any other chemicals that can lead to an undesired chemical reaction will be ruled out. Also, the spilled chemical is producing fumes, mostly it suggests that it is either a…

atoms by separating two metals. The galvanized iron was measured to two decimal places in centimeters then weighed for mass to three decimal places in grams. The galvanized iron was then stripped of it’s layer of zinc by using hydrochloric acid. The chemical reaction of the experiment is shown below: 2 HCl (aq) + Zn(s)----> H2 (g) + Zn2+(aq) + 2 Cl-(aq) Once the iron was free of the zinc layer, it was then weighed again for its new mass. The mass remaining is the mass of the iron present…

Out of many early photographic processes, I select the Anna Atkins Photographs of British Algae: Cyanotype Impressions, 1843 Cyanotype. I select this process because the color of this picture is very different to the others in the lecture making this photography stand out and get my attention. While I was doing my researches, I found out that the process to make this picture is not complicated, does not require a lot of materials, and needs a negative image which reminds me of the class activity…

CHANGES IN CHEMICAL REACTIONS INTRODUCTION This practical experiment is based is based on the theory of Law of Conservation of Mass stated by Antoine Lavoisier. Antoine Lavoisier was a French nobleman who had a major influence on the history of chemistry and biology. Today he is considered to be the “father of modern chemistry.” In all his experiment he supported the Law of Conservation of Mass. Antoine stated this in his theory, “The law of conservation of mass states that mass can neither be…

This essay will be talking about Reactions and how it affects substances.A reaction is a chemical process in which two or more substances act on each other and are changed into different substances, or one substance changes into other substances.There are eight reactions we will be talking about and they are Decomposition,Combustion,Acid and Base,Synthesis,Single-replacement,Double-replacement,Precipitation,and Redox.In the world today there are many reactions out their but we will only be…
