Answer:
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.
