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; it is conserved.

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

Back

To determine the number of atoms in a chemical formula, count the coefficients and subscripts. For example, in 4NH3, there are 4 nitrogen atoms and 12 hydrogen atoms.

What does it mean for a chemical equation to be balanced?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved.

Front

How can you tell if a chemical equation is unbalanced?

Back

A chemical equation is unbalanced if the number of atoms of any element differs between the reactants and products.

What is the total mass of products in a chemical reaction if 24 g of magnesium reacts with 38 g of fluorine?

Back

The total mass of products is 62 g, which is the sum of the masses of the reactants.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical reaction.

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.

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 the reaction.

Front

What does the arrow in a chemical equation represent?

Back

The arrow in a chemical equation represents the direction of the reaction, indicating that reactants are transformed into products.

Front

What is the purpose of balancing a chemical equation?

Back

The purpose of balancing a chemical equation is to ensure that the Law of Conservation of Mass is upheld, meaning the same number of each type of atom is present on both sides.
