combined with Element B and a bubbling and fizzing reaction started to occur 5 drops of Hcl acid solution combined with Element C and there were bubbles forming in the reaction 5 drops of Hcl acid solution combined with Element D and a dark color sits at the bottom of a pure clear substance 5 drops of Hcl acid solution were completely absorbed by Element W 5 drops of Hcl acid solution were not absorbed by Element X and there was no apparent reaction 5 drops of Hcl acid solution was not absorbed…

yield to the theoretical yield. The actual yield is the amount or mass of product actually collected during an experiment or industrial process, while the theoretical yield is the amount or mass of product predicted based on the stoichiometry of the chemical equation. In order to calculate the theoretical yield, the number of moles (the amount of substance containing 6.02x1023 entities) of each compound should be calculated according to the formula: n = m/M Where n is the number of moles, m is…

of metabolic chemical reactions, from the digestion of food to the synthesis of DNA. Enzymes catalyze chemical reactions involving the substrate. Substrate is a molecule that attach to the active site of the enzyme protein which an enzyme acts. Active site is a small port in an enzyme that helps enzyme to bind with substrates and undergo a chemical reaction. During this binding of substrates with active site it creates enzyme substrate complex, which is the complex where the reaction occurs. A…

101 Lab Section 041 9/22/14 Brandon Stroup Abstract Catalase is an enzyme found in every living organism and is essential for cells. This lab explores how catalase reacts to four different temperatures and how the concentration percentage of substrate affects its reaction rate. The performance of catalase is dependent on many factors, so the purpose of the lab was to find the ideal concentration and temperature for catalase. We hypothesized that catalase would have the fastest reaction at…

The purpose of this experiment was to see how single-replacement reactions change the physical matter of the original reactants. Hypothetically, the use of 2.120g of CuCl2 should react with the iron nails forming exactly 1 gram of copper. Upon starting the lab process, there was a displacement of 2.120 grams of CuCl2 into the plastic cup containing 50 ml DI water before joining the two iron nails. After the solution sat overnight, the iron nails became black in exterior color, orange copper…

Method 7 Results 8 Discussion 9 Conclusion 10 Appendix 10 Calculations: 13 Bibliography 13 Introduction Enzymes are core components of reactions. Enzymes can be employed to hasten, or even delay reactions. Enzymes themselves are simply biological molecules (proteins) that affect a reaction as a catalyst. A catalyst is a chemical that induces a chemical reaction. Lipase is an enzyme that the human body uses to break down fats in foods so they can be absorbed in the intestines. Furthermore,…

There are several different reactions that can be utilized in order to end with a product that includes the synthesis of carbon-carbon bonds, however for this experiment the reaction that was utilized is aldol condensation. An aldol condensation is when an enolizable aldehyde or ketone undergoes a reaction, in the presence of a base or acid, and gives a beta unsaturated ketone or aldehyde (Utah Valley University, 2009). This type of reaction can also add carbonyls to a compound, using similar…

In this lab we took a dull penny from before the year 1970 and changed its color to a shiny gold with the help of chemistry. First, we used a vinegar and salt mixture and scrubbed it onto the penny. This process cleaned all of the dark corrosion spots away and made the copper color shine like new, which then allowed us to have a clean surface to experiment on. This was mostly a physical change but their was a slight chemical reaction because of the acidity of the vinegar. We then heated granular…

form is 170.48 g/mol. Chemical properties include being able to be soluble in ammonia. Synthesis Methods of Copper (II) Chloride There are different ways this certain compound can be synthesized and prepared. If combining and heating elemental copper and diatomic…
