Front

Define Synthesis Reaction.

Back

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

Front

Define Decomposition Reaction.

Back

A reaction where a single compound breaks down into two or more simpler products.

Front

Define Single Displacement Reaction.

Back

A reaction where one element replaces another in a compound.

Front

Define Double Displacement Reaction.

Back

A reaction where two compounds exchange ions to form two new compounds.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it remains constant.

Front

How do you balance a chemical equation?

Back

By ensuring the number of atoms of each element is the same on both sides of the equation.
