Is the following reaction synthesis or decomposition?

#N_2 (g)# + #O_2 (g)# #-># #2NO (g)#

Answer 1

Synthesis.

In simple terms, a synthesis reaction is the name given to a reaction that consumes two or more reactants and produces a single product.

In this case, nitrogen gas, #"N"_2#, and oxygen gas, #"O"_2#, react to form nitric oxide, #"NO"#. Notice that two reactants are used up and a single product is formed #-># a synthesis reaction took place.
