12.1 Flashcards
List three ways in which a balanced chemical equation can be interpreted
• representative particles
• numbers of miles of particles
•
What is a role ratio
A ratio between the numbers of miles of any two substances in a balanced equation
What is the balanced chemical needed to solving stoichiometry calculations?
Balanced chemical equation
When solving stoichiometry problems, how is the correct mole ratio expressed
It can be expressed by chemical equation and using the 2 coefficients from the molecules or elements
List the four steps used in solving stoichiometric problems
G-mol
Mol-G
Mol-mol
Mol-g
What is a limiting reactant?
When it runs out first
Why is it necessary to identify the limiting reactant when you want to know how much product will form a chemical reaction?
The limiting reactant tells you how much of each reactant is formed. If you use the excess material a false answer for the calculated products will come out
What is stoichiometry?
The study of quantitative relationships between amounts of reactants used and products formed by a chemical reaction
