What is a chemical reaction?

Back

A process in which substances (reactants) undergo a chemical change to form new substances (products).

Front

Define Synthesis (Composition) Reaction.

Back

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

Front

Define Decomposition Reaction.

Back

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

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound.

Front

What is a Double Replacement Reaction?

Back

A reaction where the anions and cations of two different compounds switch places, forming two new compounds.

Front

What is a Combustion Reaction?

Back

A reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat.

Front

What is a catalyst?

Back

A substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the role of heat in chemical reactions?

Back

Heat can provide the energy needed to break bonds in reactants, facilitating the reaction.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.
