Chemical Reactions and Equations — Key Formulas
| Formula | Expression |
|---|---|
| Chemical equation balance | Same atoms on both sides; use coefficients, NOT subscripts |
| Types of reactions | Combustion (O₂), decomposition, combination, displacement, redox |
| Exothermic reaction | Releases heat/energy to surroundings (ΔH < 0) |
| Endothermic reaction | Absorbs heat/energy from surroundings (ΔH > 0) |
| Redox definition | Oxidation = loss of e⁻; reduction = gain of e⁻ |
| Oxidation state rules | Element = 0; monoatomic ion = charge; O usually -2; H usually +1 |
