Answer 1

what you think ?

Answer 2

First of all you have to know what all those reactions mean

Answer 3

decomposition is basically breaking of the compound to 2 or more different stuff
single replacement is when 2 things react and one of them replaces a part of the other compound
double replacement is when a part of a compound replaces the part of the other compound (and opposite way round)
combustion is burning of the compound using O2

Answer 4

now look at the reaction carefully and decide what is happening
