Balance the following equations: Ag 2 CO 3 → Ag + O 2 + CO 2

An equation is considered to be balanced only when it has the atoms involved in the reaction in both the reactant part and the product part are the same. As both sides are equal the balanced chemical equation for the reaction given is 2 Ag 2 CO 3 → 4 Ag + O 2 + 2 CO 2

Balance the following equations: NH 4 Cl ↔ NH 3 + HCl

An equation is considered to be balanced only when it has the atoms involved in the reaction in both the reactant part and the product part are the same. The chemical equation involved in this reaction is as follows: NH 4 Cl ↔ NH 3 + HCl The given equation is already balanced.

Balance the following equations: KNO 3 → KNO 2 + O 2

The representation of a chemical reaction in the form of substances is known as a chemical equation. While balancing the given chemical equation, count the number of atoms of each element on both sides and then try to make them equal on both sides. 2 KNO 3 → 2 KNO 2 + O 2

Balance the following equations: CuO + HCl → CuCl 2 + H 2 O

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation. CuO + 2 HCl → CuCl 2 + H 2 O

Balance the following equations: Zn + HNO 3 → Zn NO 3 2 + H 2

When the number of atoms of reactants is equal to the number of atoms of the products, the reaction is called a balanced chemical equation. Zinc reacts with nitric acid to form zinc nitrate and hydrogen gas. Zn + 2 HNO 3 → Zn NO 3 2 + H 2

Balance the following equations: Fe + H 2 O → Fe 3 O 4 + H 2

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation. 3 Fe + 4 H 2 O → Fe 3 O 4 + 4 H 2

Balance the following equations: Pb 3 O 4 → ∆ PbO + O 2

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation. 2 Pb 3 O 4 → ∆ 6 PbO + O 2

Balance the following equations: NH 4 NO 3 → N 2 O + H 2 O

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation. NH 4 NO 3 → N 2 O + 2 H 2 O
