Chemical Reaction Lab

Honors Period: 5 February 29, 2016 Chemical Reaction Lab Report Introduction A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were

Is A+C a chemical reaction? Yes, because of serval chemical changes happening to the solution before and after. I came to this conclusion by using three pieces of evidence. The three pieces of evidence were a ph imbalance, a dramatic density rise, and a change in electroconductivity. The first piece of evidence I found came from the density lab and the ABC lab. The evidence was a un-natural and substantial increase in density. The density was 0.75g/cm^3 for both A and C, but later A+C had a density

life, we witness many chemical reactions. Some fun reactions you may know about are mentos and pop or vinegar and baking soda. Those two reactions are visible to the naked eye. You aren't able to see photosynthesis completely but you know that it take place because a plant grows. Now what about the chemical reactions that you aren't able to see? How do you know when they are complete? Well let me explain this bright and interesting new discovery. Most chemical reactions develop to be transparent

Finding the Ratio of Moles and Reactants in a Chemical Reaction The main objective is not only to reach the optimum ratio to generate the greatest amount of heat and temperature, but also to maintain a constant volume throughout the entire experiment. Jenny Gao Sophia Hu 9/11/15 Procedure: My partner and I measured the temperature of NaCIO (bleach) and Na2S2O3 to prevent any misleading data. We then measured 250mL of each solution and poured 5.0mL of NaCIO and 45.0mL of Na2S2O3 in a styrofoam

A Simple Chemical Reaction with Beautiful Colors. Introduction In this lab we are going to be working on chemistry and a chemical reaction. A chemical reaction is when two or more chemical meet each other causing a change or reaction to the chemicals being mixed. We are going to do a chemical reaction ourselves, we are going to Represent this chemical reaction with milk, food coloring and dish soap. When you see this chemical reaction known as a non-polar molecule, although this is not an explosion

this lab was to apply the knowledge of chemical reactions to identify an unknown substance. Research was done prior to doing the experiment to provide a basic understanding of the chemical reactions occurring. There are two elementary aspects a chemical solution. First, there’s the reactant. The reactant is the substance added that reacts with another chemical, after the chemical reaction has run its course, what is left is called the product. There are about seven ways to tell if a chemical reaction

In this lab, we tested how chemical reactions happen when enzymes and reaction rates are effected. For the chemical reaction, we broke down the substrate ONPG into galactose and o-nitrophenol. Using ONPG as the substrate allowed us to see what was actually going on. When breaking down ONPG, the o-nitrophenol turns yellow, unlike lactose which is colorless. There are two ways in which we can manipulate the reaction rate and activation energy in this experiment. Increasing the heat by exposing enzymes

Examining the Percentage Yield of a Chemical Reaction Komal Maan 470883 Ms. Chandan April 28th, 2015   Introduction: Numerous factors can determine the percentage yield of a chemical reaction. Such as the nature of the reaction, the conditions in which the reaction is carried out and the nature of the reactants used in the reaction. In this investigation the percentage yield was to be determined using the following chemical reaction: Fe(s) + CuCl₂ (aq) FeCl₂ (aq) +Cu(s) Steel wool was used

Chemical reactions occur every day almost continuously, both in the natural world outside as well as inside living organisms. These reactions occur at varying speeds, but are usually considerably slow. Some reactions can take as long as seven years for the molecules to undergo the reaction process (Berenbaum 153-154). However, with the presence of an enzyme in the reaction, this process speeds up considerably. A reaction that takes seven years to complete, now takes less than a second to finish

on the Rate of a Reaction Introduction: A chemical reaction is the process in which atoms of the same or different elements form a new substance by rearranging themselves. The rate of reaction refers to the speed at which a chemical reaction proceeds. The rate of almost every chemical reaction can be sped up or slowed down by adding another variable. Factors such as, temperature, concentration of reactants, surface area, agitation and catalysts affect the rate of a chemical reaction. Increasing the
