What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that in a closed system, the mass of the reactants must equal the mass of the products. This means that matter cannot be created or destroyed in a chemical reaction.

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 subscripts next to each element. If there is no subscript, it means there is one atom of that element.

Front

What does the coefficient in a chemical formula represent?

Back

The coefficient in a chemical formula indicates the number of molecules or moles of that substance involved in the reaction.

Front

How many atoms are in the formula C₆H₁₂O₆?

Back

There are 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms in the formula C6H12O6.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes a change during a chemical reaction, typically found on the left side of the 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 the 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 subscripts in a chemical formula?

Back

Subscripts indicate the number of atoms of each element in a molecule. For example, in H2O, the '2' indicates there are two hydrogen atoms.

Front

What is the total mass of reactants in a reaction if the products have a mass of 10g?

Back

According to the Law of Conservation of Mass, the total mass of the reactants must also be 10g.

Front

If a reaction has 3H₂O, how many total hydrogen atoms are present?

Back

There are 6 hydrogen atoms present because 3H2O means 3 molecules of water, and each water molecule has 2 hydrogen atoms (3 x 2 = 6).
