Law of Conservation of Matter

Front

What is the Law of Conservation of Matter?

Back

The Law of Conservation of Matter states that matter cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What are reactants in a chemical equation?

Back

Reactants are the substances that undergo a chemical change in a reaction, found on the left side of a chemical equation.

Front

What are products in a chemical equation?

Back

Products are the substances that are formed as a result of a chemical reaction, found on the right side of a chemical equation.

Front

What do coefficients represent in a chemical equation?

Back

Coefficients are the numbers placed before the compounds in a chemical equation that indicate the number of molecules or moles of that substance.

Front

What do subscripts represent in a chemical formula?

Back

Subscripts are the small numbers in a chemical formula that indicate the number of atoms of an element in a molecule.

Front

How can you tell if a chemical equation follows the Law of Conservation of Matter?

Back

A chemical equation follows the Law of Conservation of Matter if the number of atoms of each element is the same on both sides of the equation.

Front

What is the significance of balancing a chemical equation?

Back

Balancing a chemical equation ensures that the same number of each type of atom is present on both sides, reflecting the Law of Conservation of Matter.

Front

What is an example of a balanced chemical equation?

Back

An example of a balanced chemical equation is: 2H2 + O2 → 2H2O.

Front

What happens to the mass of reactants and products in a chemical reaction?

Back

The total mass of the reactants is equal to the total mass of the products in a chemical reaction.

Front

What is a chemical reaction?

Back

A chemical reaction is a process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of bonds.
