Introduction to lab: In this lab, you will be conducting a reaction between sodium carbonate and calcium chloride and measuring the mass of one of the products collected. By comparing the amount of products collected (Actual yield) to the maximum amount of product that could have been produced (Theoretical yield), you will be able to determine the percent yield of the reaction. Question: Write the purpose for this lab, taking into account information from the introduction.

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
