Reaction Balancing

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 equal numbers of each type of atom on both sides of the equation, ensuring that mass is conserved.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure the same number of each type of atom appears on both sides.

Front

What is a coefficient in a chemical equation?

Back

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

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical reaction, found on the left side of a chemical 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, found on the right side of a chemical equation.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations is crucial because it reflects the conservation of mass and allows for the accurate calculation of reactants and products.
