Correctly identify the generic formula for a double replacement reaction.

a. ab + cd + ad + cb
d. cxhy + o2 → co2 + h2o
b. ab + a+b
e. ab + c → ac + b
c. a + b → ab

AB + CD → AC +BD

Explanation:

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

Example:

The following reaction is double replacement reaction.

CaCO₃ + 2HCl  → CaCl₂ + H₂CO₃

While,

A + B → AB

Synthesis reaction:

It is synthesis reaction. The reaction in which two or more simple substance react to give one or more complex product.

AB → A + B

Decomposition:

It is the decomposition reaction. The reaction in which one reactant is break down into two or more product.

AB + C → AC + B

Single replacement:

It is the reaction in which one elements replace the other element in compound.
