Computer The Determination of a Chemical Formula 1 Second‚ you will conduct a chemical reaction with the dried sample‚ which will produce elemental copper. By measuring the mass of copper that forms‚ you will have the necessary information to determine the moles of copper and chlorine in your sample‚ and you will be able to establish the proper chemical formula. OBJECTIVES • • • In this experiment‚ you will Ev al Determine the water of hydration in a copper chloride hydrate

2013 Title: Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and to associate chemical properties with household products. Procedure: In this experiment I used a 96-well plate to hold each of the chemical reactions that occurred during this lab. Using a pipet‚ I added two drops of one chemical with two drops of another chemical and observed the effects of each reaction. Data Table 1: Experimental Data Well # | Chemicals | Observations | |

This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is

Chemical changes are irreversible because substances mix and cause a reaction which creates a new substance. Chemical changes can be caused when a substance is combined with a heat‚ water or another substance. Heat can cause a chemical reaction called caramelisation which is when sugar is heated at a high temperature causing it to break down. This gives the sugar a nutty taste and causes it to brown. Physical changes are changes that change the physical appearance‚ smell and
