Classify each chemical reaction as a synthesis, decomposition, single-displacement, or double-displacement reaction.
(a) K2S(aq) + Co(NO3)2(aq) → 2 KNO3(aq) + CoS(s)
(b) 3 H2(g) + N2(g) →2 NH3(g)
(c) Zn(s) + CoCl2(aq) → ZnCl2(aq) + Co(s)
Here, we have to find out the type of each reaction.
Synthesis: When two or more molecules combine together to form a new compound is called synthesis.
Decomposition :It is a chemical reaction where a single compound splits into two or more simple substances under suitable conditions.
Single displacement reaction: It is a chemical reaction where an element reacts with a compound and takes the place of another element in that compound.
Double displacement reaction: It is a chemical reaction where two compounds react, and the positive ions (cation) and the...
