Answer 1

Al + + GaP ➡️ Ga + AIP

This is a single replacement reaction.

2 Mg + O2 ➡️ MgO

This is a combination (synthesis) reaction.

CH4 + 2O2 ➡️ CO2 + 2H2O

This is a combustion reaction.

2 NaCl ➡️ Na + Cl2

This is a decomposition reaction.

Overall, the types of chemical reactions involved in the given reactions are:

1 single replacement reaction
1 combination (synthesis) reaction
1 combustion reaction
1 decomposition reaction
