  1. Chemistry 12.2 Section 12.2-1 Chemical Calculations

  2. Chemical Calculations 12.2-1 • The effectiveness of car’s air bags is based on the rapid conversion of a small mass of sodium azide, NaN3, into a large volume of nitrogen gas. The entire reaction occurs in less than a second. You will learn how to use a balanced chemical equation to calculate the amount of product formed in a chemical reaction.

  3. 12.2-1 Writing and Using Mole Ratios • Writing and Using Mole Ratios • How are mole ratios used in chemical calculations?

  4. 12.2-1 Writing and Using Mole Ratios • In chemical calculations, mole ratios are used to convert between moles of reactant and moles of product, between moles of reactants, or between moles of products.

  5. 12.2-1 Writing and Using Mole Ratios • Mole-Mole Calculations • A mole ratio is a conversion factor derived from the coefficients of a balanced chemical equation interpreted in terms of moles.
