The symbol equation shows the atoms on both sides:
A chemical reaction can be described by the process: REACTANT à PRODUCTS
E.g. Magnesium + Oxygen à Magnesium Oxide
Balancing the equation – Match them up one by one:
1. There must always be the same number of atoms on both sides – they can’t just disappear.
2. Balance the equation by putting numbers in front of the formulas where needed.
Equation for reacting sulphuric acid with sodium hydroxide:
