Page 1: Introduction to Stoichiometry and Balanced Equations

The first page introduces fundamental concepts of stoichiometry and balanced chemical equations. The law of conservation of matter forms the basis for understanding chemical reactions mathematically.

Definition: Stoichiometry is the mathematics of chemistry used to determine the amount of reactants consumed or products produced from balanced chemical equations.

Example: In the reaction 2H₂ + O₂ → 2H₂O, the coefficients show that 2 moles of H₂ react with 1 mole of O₂ to produce 2 moles of H₂O.

Highlight: Coefficients in balanced equations represent the number of moles of each substance.

Vocabulary: Mole ratio - the relationship between the amounts of reactants and products in a balanced equation.

The page demonstrates how to solve basic stoichiometry problems using mole ratios and balanced equations, including a practice problem involving nitrogen and hydrogen to produce ammonia.
