1. 7.1Mole Ratios in Chemical Equations

2. Recall Balancing Equations!!!

3. The Mole Ratio
The coefficents in the equation give the ratio of one chemical to another chemical used in the reaction.
The ratios tell chemists how much of each reactant is needed.
It lets us maximize output while minimizing inputs.
It allows us to move from one chemical to another in mathematical calculations
