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

Back

A decomposition reaction breaks down a compound into simpler substances, while a synthesis reaction combines two or more substances to form a more complex compound.

Front

What is a subscript in a chemical formula?

Back

A subscript is a number written below and to the right of a chemical symbol that indicates the number of atoms of that element in a molecule.

Front

What does the term 'reactants' refer to in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change in a reaction.

Front

What does the term 'products' refer to in a chemical reaction?

Back

Products are the substances formed as a result of a chemical reaction.

Front

What is a synthesis reaction?

Back

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