Chemical Reactions

Front

What is a chemical reaction?

Back

A process where reactants transform into products, involving the breaking and forming of chemical bonds.

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.

Front

What is an exothermic reaction?

Back

A chemical reaction that releases energy, usually in the form of heat.

Front

What is an endothermic reaction?

Back

A chemical reaction that absorbs energy from its surroundings.

Front

What is a reactant?

Back

A substance that undergoes change during a chemical reaction.

Front

What is a product?

Back

A substance that is formed as a result of a chemical reaction.

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 activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What is equilibrium in a chemical reaction?

Back

A state where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.

Front

What is a balanced chemical equation?

Back

An equation that shows the same number of each type of atom on both sides, reflecting the law of conservation of mass.
