Mole- Mole Chemistry
In this lab we studied stoichiomentry. We also reviewed the mole-mole relationship between copper and iron in a chemical reaction. The stoichiomentry of mass is that during the heating the experiment does loose mass .This mean that mole and mass did change. An Example of real world is Masses and volumes of products are extremely important in key reactions such as the deployment of air bags in vehicles, carbon dioxide production to help bread rise, and the
Production of ammonia gas for industries.
To do this lab we weighed Copper. Than we weighed the iron nail. Next, we put the nail into the hot copper and sit for 10 minutes. Finally we weighed the filter paper and recorded the mass in our data table.
Our result for this lab was that both total product and the mass of the total reactants was 2.71g we had a 2.5 difference. This shows that we did not validate the stoichiometry of mass. That we lose moles or it’s mass. The physical changes in this lab were that the blue copper rocks changed to blue liquid. The Error we faced in this lab was that copper residue did not end up in the filter paper.
II. Objective
· To determine the mole –mole relationship between copper and iron in a chemical reaction
· To predict the amount of copper used based on the amount of iron consumed
