Balancing Chemical Equations

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, indicating that mass is conserved during the reaction.

Front

What are reactants in a chemical equation?

Back

Reactants are the substances that undergo a chemical change in a reaction, found on the left side of the equation.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What does the arrow (→) in a chemical equation represent?

Back

The arrow indicates the direction of the reaction, showing that reactants are transformed into products.

Front

How do you determine the coefficients in a balanced equation?

Back

Coefficients are determined by adjusting the numbers in front of the compounds to ensure the same number of each type of atom on both sides.

Front

What is the law of conservation of mass?

Back

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

Balance the equation: _Al + _HCl → _H₂ + _AlCl₃

Back

2Al + 6HCl → 3H₂ + 2AlCl₃

Front

Balance the equation: _CF₄ + _Br₂ → _CBr₄ + _F₂

Back

1CF₄ + 2Br₂ → 1CBr₄ + 2F₂

Front

Balance the equation: _CH₄ + _O₂ → _CO₂ + _H₂O

Back

1CH₄ + 2O₂ → 1CO₂ + 2H₂O

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula to indicate how many molecules or moles of that substance are involved in the reaction.
