Stoich

Question 1

What is Stoichiometry

Answer 1

The quantitative analysis of chemical reactions

Question 2

Explain the difference between excess reactant and a limiting reactant

Answer 2

Excess reactants do not run out during a reaction. Limiting reactants run out during a reaction stopping the reaction. This is important because this determines the amount of product made in a reaction.

Question 3

Explain the difference between actual and theoretical yield, thinking of the labs we have done what are some ways that you could get over 100% or under 100%?

Answer 3

Actual or experimental yields are determined in lab and are subject to error. Theoretical yields are determined through stoichiometry and are perfect answers.
