Question

Balancing chemical equations

Answer 1

Explanation:

A balanced chemical equation is one in which the law of conservation of matter is obeyed. The law states that "matter is neither created nor destroyed in the course of a chemical reaction".

This implies that the total mass of the products of a reaction is exactly the same as the total mass of the reacting substances.

In balancing a chemical equation, there is conservation of all kinds of atoms involved in the reaction being represented by the equation.

• Appropriate numbers called coefficients are put in front  of the formula to balance an equation.
• Subscripts should not be altered in an attempt to balance equation.

Some methods can be used in balancing chemical equations;

A trial and error method is useful for balancing simple equations and it involves putting appropriate coefficients in front of the formula of the reactants or products as to achieve a conservation of all atoms.

In a mathematical approach, simple algebraic equations are set up for equations that cannot be simply balanced by inspection. This involves using simple algebraic equations for each kind of atoms or groups taking part in a reaction so as to achieve the conservation of all atoms or groups.
