Balance each equation by writing the correct coefficient (put a space in the box if no coefficient is needed). Then, identify the type of reaction taking place.

1. CaCO3 → CaO+CO2
_CaCO3 → _CaO+_CO2 is a decomposition reaction.
2. O2+ N2 → NO2
_O2+_N2 → _NO2 is a synthesis reaction.
3. FeS+ HCl → FeCl2+ H2S
_FeS+_HCl → _FeCl2+_H2S is a replacement reaction.
