Chemical reactions surround us. Types of reactions, reaction rates, catalysts, acids and bases — and what happens at the particle level.
Classify reactions by what's happening at the particle level.
Building up and breaking down — two fundamental reaction types.
Fire, rusting and breathing — all involve oxygen.
The pH scale — from stomach acid to baking soda.
Acid plus base — they cancel each other out.
When two clear solutions make a solid.
Four ways to make a reaction go faster or slower.
More collisions and more energetic — double the rate increase.
More exposed surface means more places for reactions to start.
Speed up the reaction without being used up.
Exothermic reactions release energy — endothermic ones absorb it.
Apply reaction chemistry to a real-world problem.
