Senior 2 Chemistry: Chemical Equations by Katenta Joseph

These notes introduce chemical equations by distinguishing reactants from products and word equations from symbolic representations. They explain how to select correct formulae, represent diatomic elements, balance atoms using coefficients, and add physical state symbols. Worked examples cover reactions forming magnesium oxide, iron(III) chloride, water and potassium fluoride. Further examples explore decomposition, displacement and reactions involving acids. Three exercises ask learners to convert word equations into chemical equations and balance supplied equations.
