A _______ reaction occurs when two or more substances combine to form a new substance.

Understand the Problem

The question is asking for the correct term to describe a specific type of chemical reaction where multiple substances combine to create a new substance. This pertains to chemistry concepts.

More Information

Combination reactions are also known as synthesis reactions. They involve the merging of two or more reactants to create a single product. This type of reaction is fundamental in chemical synthesis and can occur between different states of matter (solids, liquids, gases).

Tips

A common mistake is confusing combination reactions with decomposition reactions, which involve breaking down compounds into simpler substances.
