Question

(E) Give the balanced chemical equations:

i. Silver nitrate reacts with sodium chloride, forms silver chloride and sodium nitrate.

ii. Steam is formed on passing an electric spark through a mixture of hydrogen and oxygen.

iii. A piece of magnesium, when burnt in nitrogen, forms solid magnesium nitride.

iv. A piece of potassium violently reacts with water to form an aqueous solution of potassium hydroxide.

v. Magnesium will react with dilute sulphuric acid to form magnesium sulphate and hydrogen gas is evolved.​

Answer 1

Explanation:

1.Silver nitrate reacts with sodium chloride, forms silver chloride and sodium nitrate.

AgNO3+NaCL--->AgCL+NaNO3

2.Steam is formed on passing an electric spark through a mixture of hydrogen and oxygen.

3.A piece of potassium violently reacts with water to form an aqueous solution of potassium hydroxide.

2 K +2H2O ---------> 2KOH +H2

4.A piece of potassium violently reacts with water to form an aqueous solution of potassium hydroxide.

2 K +2H2O ---------> 2KOH +H2

5. Magnesium will react with dilute sulphuric acid to form magnesium sulphate and hydrogen gas is evolved.

2MgSO4+ H2SO4 -------->2Mg(HSO4)2
