Slide 1 of 30 © Copyright Pearson Prentice Hall > The Arithmetic of Equations Using Everyday Equations A balanced chemical equation provides the same kind of quantitative information that a recipe does. 12.1

Slide 2 of 30 © Copyright Pearson Prentice Hall > The Arithmetic of Equations Using Everyday Equations An equation can represent the manufacturing of a single tricycle. 12.1

Slide 3 of 30 © Copyright Pearson Prentice Hall > The Arithmetic of Equations Using Balanced Chemical Equations Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or product is formed in a reaction. The calculation of quantities in chemical reactions is a subject of chemistry called stoichiometry. 12.1
