Answer the following questions.

Explain the difference between a combination and dissociation reaction.

A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).

Such reactions may be represented by equations of the following form: X + Y → XY.

Here X and Y are the reactants and XY is the product.

Eg:

A dissociation reaction is a chemical reaction where a compound breaks apart into two or more parts.

The general formula for a dissociation reaction follows the form: AB → A + B.

Dissociation reactions are usually reversible chemical reactions.

Eg:
