When balancing chemical equations the number of atoms of each element must be the same for both sides (reactants and products) of the chemical equation.
Complete reaction: H2 + N2 → NH3
In the following diagram, the white spheres represent hydrogen atoms and the blue spheres represent nitrogen atoms.
The two reactants combine to form a single product, ammonia, NH3, which is not shown. Write a balanced chemical equation for the reaction. Based on the equation and the contents of the left (reactants) box how many molecules should be shown in the right (products) box?
