Translate the following statements into chemical equations and then balance them. Hydrogen gas combines with nitrogen to form ammonia.

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charges are the same for both the reactants and the products. The balanced chemical equation for the reaction of hydrogen with nitrogen to form ammonia is: 3 H 2 g + N 2 g → 2 NH 3 g

Translate the following statements into chemical equations and then balance them. Hydrogen sulphide gas burns in the air to give water and sulphur dioxide.

Hydrogen sulphide gas burns in the air to give water and sulphur dioxide. A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charges are the same for both the reactants and the products. The balanced chemical equation for the reaction of hydrogen sulphide gas in air is: 2 H 2 S g Hydrogen sulphide + 3 O 2 g Oxygen → 2 H 2 O l Water + 2 SO 2 g sulphur dioxide

Translate the following statements into chemical equations and then balance them. Potassium metal reacts with water to give potassium hydroxide and hydrogen gas.

Potassium metal reacts with water to give potassium hydroxide and hydrogen gas. The balanced chemical equation is: 2 K ( s ) + 2 H 2 O ( l ) → 2 K O H ( a q ) + H 2 ( g ) A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charges are the same for both the reactants and the products. The equation is balanced by the hit and trial method. It always follows the Law of Conservation of mass .

Balance the following chemical equation: HNO 3 + Ca ( OH ) 2 → Ca ( NO 3 ) 2 + H 2 O

Total mass on the reactant side and product side will be equal in a balanced equation. Balanced chemical equation for the reaction is: 2 HNO 3 + Ca ( OH ) 2 → Ca ( NO 3 ) 2 + 2 H 2 O

Balance the following chemical equation: NaOH + H 2 SO 4 → Na 2 SO 4 + H 2 O

A balanced chemical equation should contain equal number of atoms on both the sides of the equation. The given reaction represents the neutralisation reaction of sodium hydroxide with sulphuric acid to produce sodium sulphate and water. Therefore, the given equation can be balanced as, 2 NaOH + H 2 SO 4 → Na 2 SO 4 + 2 H 2 O

Balance the following chemical equation: N a C l + A g N O 3 → A g C l + N a N O 3

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charges are the same for both the reactants and the products. This is a double displacement reaction. The balanced chemical equation for the given reaction is: N a C l + A g N O 3 → A g C l + N a N O 3

Balance the following chemical equation: B a C l 2 + H 2 S O 4 → B a S O 4 + H C l

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charges are the same for both the reactants and the products. The balanced chemical equation for the given reaction is: B a C l 2 + H 2 S O 4 → B a S O 4 + 2 H C l

Identify the substance that is oxidised and reduced in the following reaction- MnO 2 + 4 HCl → MnCl 2 + 2 H 2 O + Cl 2

In the given reaction, MnO 2 is losing oxygen to form MnCl 2 and HCl is losing hydrogen to form Cl 2 . MnO 2 Manganese dioxide + 4 HCl Hydrochloric acid → MnCl 2 Manganese dichloride + 2 H 2 O Water + Cl 2 Chlorine Therefore, we can conclude- Substance that is oxidised and which is acting as a reducing agent is HCl . Substance that is reduced and which is acting as an oxidising agent is MnO 2 .
