Front

Define a synthesis reaction.

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product.

Front

What is the general formula for a synthesis reaction?

Back

A + B → AB.

Front

What is the difference between a synthesis and a decomposition reaction?

Back

A synthesis reaction combines reactants to form a product, while a decomposition reaction breaks down a compound into simpler products.

Front

Provide an example of a decomposition reaction.

Back

2H₂O → 2H₂ + O₂.

Front

What is the role of heat in decomposition reactions?

Back

Heat can provide the energy needed to break chemical bonds in a compound, facilitating its decomposition.
