Question

1. Write the balanced equation for the following chemical reactions.
(i) Hydrogen + Chlorine → Hydrogen chloride
(ii) Barium chloride + Aluminium sulphate → Barium sulphate +
Aluminium chloride
(iii) Sodium + Water Sodium hydroxide + Hydrogen
2. Write a balanced chemical equation with state symbols for the
following reactions.
(i) Solutions of barium chloride and sodium sulphate in water react
to give insoluble barium sulphate and the solution of sodium
chloride.
(ii) Sodium hydroxide solution in water) reacts with hydrochloric
acid solution (in water) to produce sodium chloride solution and
water.​

Answer 1

Answer:

Explanation:

1. (i) H2 +Cl2 = 2HCL

(ii) Al2(SO4)3 + 3BaCl2 =  2AlCl3 + 3BaSO4

(iii) 2Na+2H2O= 2NaOH+H2

2.

(i)  BaCl2 +Na2SO4 = BaSO4 + 2NaCl

(ii) NaOH + HCl = NaCl + H2O

Answer 2

Solution:

1. The balanced equation for the following chemical reactions are:

(i) Hydrogen + Chlorine $\rightarrow$ Hydrogen chloride

$H_{2 (g)}+Cl_{2 (g)} \rightarrow 2HCl _{(g)}$

(ii) Barium chloride + Aluminium sulphate $\rightarrow$ Barium sulphate +

Aluminium chloride

$3BaCl_2 + Al_2(SO_4)_3 \rightarrow 3BaSO_4 + 2AlCl_3$

(iii) Sodium + Water $\rightarrow$ Sodium hydroxide + Hydrogen

$2Na + 2H_2O \rightarrow 2NaOH + H_2$

2. The balanced chemical equation with state symbols for the

following reactions are:

(i) Solutions of barium chloride and sodium sulphate in water react

to give insoluble barium sulphate and the solution of sodium

chloride.

$BaCl_2 (aq) + Na_2SO_4 (aq) \rightarrow BaSO_4 (s) + 2NaCl (aq)$

(ii) Sodium hydroxide solution in water reacts with hydrochloric

acid solution (in water) to produce sodium chloride solution and

water.​

$NaOH (aq) + HCl (aq) \rightarrow NaCl (aq) + H_2O (l)$
