The correct answer is option C: Law of conservation of mass.
Explanation:
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. In other words, the total mass of the reactants must be equal to the total mass of the products.
A balanced chemical equation is an equation that represents a chemical reaction with an equal number of atoms of each element on both sides of the equation. It follows the law of conservation of mass by ensuring that the total mass of the reactants equals the total mass of the products.
Let's take an example to understand this concept better:
Consider the combustion of methane (CH4) in oxygen (O2) to form carbon dioxide (CO2) and water (H2O):
CH4 + 2O2 → CO2 + 2H2O
In this equation, we have one carbon atom on the left side (reactants) and one carbon atom on the right side (products). We also have four hydrogen atoms on the left side and four hydrogen atoms on the right side. Similarly, we have four oxygen atoms on the left side and four oxygen atoms on the right side. The equation is balanced because the number of atoms of each element is the same on both sides.
If the equation was not balanced, it would violate the law of conservation of mass. For example, if we had two carbon atoms on the left side and only one carbon atom on the right side, mass would be lost or gained in the reaction, which is not possible.
Therefore, a balanced chemical equation is in accordance with the law of conservation of mass. It ensures that the total mass of the reactants is equal to the total mass of the products, maintaining the principle that matter cannot be created or destroyed in a chemical reaction.

- The Law of conservation of mass states that mass can neither be created nor destroyed but can be transformed from one form to another.
- A balanced chemical equation is in accordance with the law of conservation of mass i.e the atoms of the reactants are just rearranged to form products but the total amount of mass in chemical reaction remains constant.
- Avogadro's Law states that at the constant temperature and pressure, the volumes of gas is directly proportional to the number of molecules.
- Law of multiple proportion states that when two elements combine to form two or more compounds, then the ratio of the mass of one element that combines with the fixed mass of the other element will always be simple whole numbers.
- Gay-Lussac's Law of gaseous volumes states that at constant volume, the pressure of the given mass of a gas is directly proportional to the temperature in Kelvin.
