Conservation of Mass

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

How do you determine the number of atoms in a molecular formula?

Back

To determine the number of atoms in a molecular formula, count the subscripts for each element in the formula. If no subscript is present, it is assumed to be 1.

In the molecular formula C6H12O6, how many Carbon atoms are present?

Back

There are 6 Carbon atoms in the molecular formula C6H12O6.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical reaction, typically found on the left side of a chemical equation.

Front

What is a product in a chemical reaction?

Back

A product is a substance that is formed as a result of a chemical reaction, typically found on the right side of a chemical equation.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms of each element is the same on both sides of the equation.

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of molecules or moles of a substance involved in a chemical reaction and are used to balance the equation.

How many Oxygen atoms are in the reactants of the equation 2H2 + O2 -> 2H2O?

Back

There are 2 Oxygen atoms in the reactants of the equation 2H2 + O2 -> 2H2O.

Front

What is the total number of atoms in the reactants of the equation 2H2 + O2?

Back

The total number of atoms in the reactants 2H2 + O2 is 6 (4 Hydrogen atoms and 2 Oxygen atoms).

Front

What is the relationship between the number of atoms in reactants and products according to the Conservation of Mass?

Back

According to the Conservation of Mass, the number of atoms in reactants must equal the number of atoms in products.
