Balancing Equations

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:

H2SO4
