Decomposition Reaction: A single reactant breaks down into two or more simpler products. This can happen through heat (thermal), light (photolysis), or electricity (electrolysis).Example: 2Pb(NO3)2 → 2PbO + 4NO2 + O2

Combination Reaction: Two or more reactants combine to form a single product.Example: CaO(s) + H2O(l) → Ca(OH)2(aq) (Slaking of lime)

Understanding the different ways substances interact is key to this chapter. The main types include: Decomposition Reaction: A single reactant breaks down into

Rancidty: The oxidation of fats and oils in food, leading to an unpleasant smell and taste. This can be prevented by using antioxidants or flushing food containers with nitrogen gas. Download PDF Notes

To balance an equation, we use the hit-and-trial method to adjust coefficients until the number of atoms matches on both sides. For example:Unbalanced: Fe + H2O → Fe3O4 + H2Balanced: 3Fe + 4H2O → Fe3O4 + 4H2 Types of Chemical Reactions This can be prevented by using antioxidants or

Oxidation isn't just a laboratory concept; it affects us every day:
