Question

Complete the following reactions :

Ba(N3)2 ---heat------>

HgCl2 + PH3------->

PCl3 + 3H2O------->

S + H2SO4 (conc.)------>

Al2O3(s) + NaOH (aq) + H2O(l) ----->

Answer 1

Ba(N3)2 → Ba + 3 N2

3 HgCl2 + 2 PH3 → Hg3P2 + 6 HCl

3H2O + PCl3 → H3PO3 + 3 HCl

S + H2SO4 → SO2 + H2O

Al2O3(s) + 2 NaOH(aq) → 2 NaAlO2 + H2O

NaAlO2 + 2 H2O → Al(OH)3 + NaOH

Answer 2

For a:  $Ba(N_3)_2\xrightarrow[]{\Delta } Ba+3N_2$

For b:  $3HgCl_2+2PH_3\rightarrow Hg_3P_2+6HCl$

For c:  $PCl_3+3H_2O\rightarrow H_3PO_3+3HCl$

For d:  $S+2H_2SO_4\text{( conc.)}\rightarrow 3SO_2+2H_2O$

For e:  $Al_2O_3+2NaOH+3H_2O\rightarrow 2NaAl(OH)_4$

Explanation:

Every balanced chemical equation follows law of conservation of mass.

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

For the given options:

• For a:

The balanced chemical equation is:

$Ba(N_3)_2\xrightarrow[]{\Delta } Ba+3N_2$

• For b:

The balanced chemical equation is:

$3HgCl_2+2PH_3\rightarrow Hg_3P_2+6HCl$

• For c:

The balanced chemical equation is:

$PCl_3+3H_2O\rightarrow H_3PO_3+3HCl$

• For d:

The balanced chemical equation is:

$S+2H_2SO_4\text{( conc.)}\rightarrow 3SO_2+2H_2O$

• For e:

The balanced chemical equation is:

$Al_2O_3+2NaOH+3H_2O\rightarrow 2NaAl(OH)_4$
