Balancing Chemical Equations

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products along with their quantities.

Front

What does it mean to balance a chemical equation?

Back

Balancing a chemical equation means ensuring that the number of atoms of each element is the same on both sides of the equation.

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction.

Front

How do you identify reactants and products in a chemical equation?

Back

Reactants are the substances that undergo a chemical change, found on the left side of the equation, while products are the substances formed, found on the right side.

Front

What is the purpose of coefficients in a chemical equation?

Back

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

Balance the equation: __C + __O₂ → __CO₂.

Back

1, 1, 1

Front

What is a skeleton equation?

Back

A skeleton equation is a chemical equation that shows the reactants and products but not their coefficients.

Front

What is the difference between a balanced equation and a skeleton equation?

Back

A balanced equation has equal numbers of each type of atom on both sides, while a skeleton equation does not.

Front

How do you balance the equation: __Fe + __O₂ → __Fe₂O₃?

Back

4, 3, 2

Front

What is the significance of the states of matter in a chemical equation?

Back

The states of matter (solid, liquid, gas, aqueous) indicate the physical form of the reactants and products.
