what you think ?

somy · Answer

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

somy · Answer

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

now look at the reaction carefully and decide what is happening
