Sodium carbonate reacts with HCl acid to liberate $\mathrm{CO}_{2}$. Find the number of moles of $\mathrm{CO}_{2}$. Also find the volume obtained at STP when 1 mole of sodium bicarbonate is used.

Answer:

$\mathrm{Na}_{2}\mathrm{CO}_{3} + 2\mathrm{HCl} = \mathrm{H}_{2}\mathrm{O} + \mathrm{CO}_{2} + 2\mathrm{NaCl}$

According to the equation, the number of moles of $\mathrm{CO}_{2}$ formed is 1.

$\mathrm{n(Na_2CO_3) = n(CO_2) = 1\ mole}$

$\mathrm{n(CO_2) = V / 22.4}$

$\mathrm{V(CO_2) = 1\cdot 22.4 = 22.4\ l}$
