Oxides, and water (and water is an oxide of hydrogen).

Explanation:

Typically we combust hydrocarbons; certainly, we do so in order to make our goggomobiles go.

If we represent petrol or diesel as hexanes:

$C_{6} H_{14} (l) + \frac{19}{2} O_{2} (g) \to 6 C O_{2} (g) + 7 H_{2} O (l)$ $C_6H_14(l) + 19/2O_2(g) rarr 6CO_2(g) + 7H_2O(l)$

Of course combustion is never complete in an internal combustion engine; some products of incomplete combustion result, i.e. $C O$ $CO$ and particulate $C$ $C$ .

$C_{6} H_{14} (l) + 8 O_{2} (g) \to 4 C O_{2} (g) + C (s) + C O (g) + 7 H_{2} O (l)$ $C_6H_14(l) + 8O_2(g) rarr 4CO_2(g) + C(s) + CO(g) + 7H_2O(l)$

Are mass and charge conserved in these reactions? If not, they should be!
