Question

Q2. Balance the following chemical equations:

$\mathrm{NaCl}+\mathrm{AgNO}{}_3\to \mathrm{AgCl}+\mathrm{NaNO}{}_3$

Answer 1

Balancing of chemical equation:

Step 1: Write unbalanced equation.

$\mathrm{NaCl}+\mathrm{AgNO}{}_3\to \mathrm{AgCl}+\mathrm{NaNO}{}_3$

Step 2: Write down the number of atoms of each elements present on both reactant as well as product side.

Element Reactant side Product side

$\mathrm{Na}$ $1$ $1$

$\mathrm{Cl}$ $1$ $1$

$\mathrm{Ag}$ $1$ $1$

$\mathrm{N}$ $1$ $1$

$\mathrm{O}$ $3$ $3$

Step 3: It is already a balanced equation

Balanced equation:

$\mathrm{NaCl}\left(\mathrm{aq}\right)+\mathrm{AgNO}{}_3(\mathrm{aq})\to \mathrm{AgCl}(\mathrm{aq})+\mathrm{NaNO}{}_3(\mathrm{aq})$
