3/15/2016 I ObjectiveDo Now Define what a mole ratio is and apply the concept to balanced chemical equations. Take out the “Butters” worksheet and make a pile in the middle of your table. Then… Consider the following balanced chemical equation: 2 FeCl Zn → 2 Fe + 3 ZnCl 2 The mole ratio of zinc to iron is 3:2. How many other mole ratios can you identify in the equaiton?

Reminders Grams/Moles Calculations go in the late folder if you did not show them to me yesterday. If you are missing any of the last three quizzes, you may make them up today after school in room 309.

Mole Ratio The ratio between the amounts in moles of any two compounds involved in a chemical reaction Mole ratios are used as conversion factors between two reactants, two products, or a reactant and a product in a balanced chemical equation.
