Consider the reaction between ammonia (NH3) and oxygen (O2) to produce nitrogen gas (N2) and water vapour (H2O):
4NH3(g) + 3O2(g) → 2N2(g) + 6H2O(g)
Complete the following statement. The above equation may be best read as:
a 4 atoms of ammonia react with 6 atoms of oxygen to produce 4 atoms of nitrogen and 6 atoms of water.
b 4 atoms of ammonia react with 3 atoms of oxygen to produce 2 atoms of nitrogen and 6 atoms of water
c 4 molecules of ammonia react with 3 molecules of oxygen to produce 2 molecules of nitrogen and 6 molecules of water.
