Explanation:

1.(a)

DIRECT COMBINATION:

A synthesis reaction or direct combination reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. The reactants may be elements or compounds, while the product is always a compound.

DECOMPOSITION REACTION:

A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is: AB→A+B. Most decomposition reactions require an input of energy in the form of heat, light, or electricity.

(b)

DISPLACEMENT REACTION:

A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when iron is added to a copper sulphate solution, it displaces the copper metal. A + B-C → A-C + B. The above equation exists when A is more reactive than B.

NEUTRALIZATION REACTION:

neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
