Law of Conservation of Mass Flashcard

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.

Front

What is a balanced chemical equation?

Back

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

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change in a reaction.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

How do you determine the number of atoms in a compound?

Back

The number of atoms in a compound can be determined by looking at the coefficients and subscripts in the chemical formula.

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 reaction, affecting the total mass.

Front

How do you solve for an unknown mass in a chemical equation?

Back

To solve for an unknown mass, you can use the equation of mass conservation: total mass of reactants = total mass of products.

Front

What is the formula for calculating the total mass of products?

Back

Total mass of products = mass of reactants - mass of any lost substances (if applicable).

Front

What is the role of zinc in a chemical reaction involving zinc carbonate?

Back

Zinc is a reactant that contributes to the total mass and is conserved during the reaction.

Front

How do you identify a balanced equation from a list of equations?

Back

To identify a balanced equation, count the number of atoms of each element on both sides of the equation and ensure they are equal.
