WebWrite it out on a piece of paper and underneath each side of the equation write out how many of each atom there are. N2 + H2 -> NH3 On the left there is 2 N and 2 H On the right there is 1 N and 3 H If we tried to balance starting with H you'd need to use a fraction or decimal and would get messy, so let's start with N. WebGizmo Warm-up Burning is an example of a chemical reaction.The law of conservation of matter states that no atoms are created or destroyed in a chemical reaction.
