All this are good<3

Answer 2

Combustion is a reaction with oxygen with high energy (heat)
synthesis is the formation of a single bigger compound from combining several smaller compounds.
Decomposition means a bigger compound gets split into several smaller compounds

Single displacement is generally observed in metal-metal solution reactions. Consider two metals A and B with A in salt form as AX and B as a pure metal. If B is more reactive than A, B swaps with A out of solution: Notice A and B have swapped - this is also more broadly a redox reaction.

AX(aq) + B(s) --> BX(aq) + A (s)

Double displacement means more than two ion pairs have swapped. This often occurs in precipitation reactions.

For eg. AX + BY --> AY + BX eg.

Ba(OH)2 (aq) + CuSO4 (aq) --> BaSO4 (S) + Cu(OH)2 (aq)

Acid-base neutralisation reaction: Acid + Base --> Salt + water
