Chemical reactions and equations become easier when an equation is treated as a representation of what is happening rather than a string of symbols to memorise. Start by identifying the reactants and products. Then balance the equation by changing coefficients, not chemical formulas. Learn to recognise common reaction patterns such as combination, decomposition, displacement, and double displacement. Pay attention to observations such as colour change, gas formation, temperature change, or precipitate formation when relevant. During revision, practise writing and balancing equations without looking at your notes, then explain the reaction type in your own words.
