Question

Write the balanced chemical equation for the following:
1} Dilute hydrochloric acid reacts with sodium carbonate.

Answer 1

Dilute Hydrochloric$\left(HCl\right)$ acid reacts with sodium carbonate$\left(N{a}_{2}C{O}_3\right)$ to produce sodium chloride ($NaCl)$, carbon dioxide($C{O}_2$), and water($H_{2}O$). Brisk effervescence is seen due to the formation of carbon dioxide gas.

The balanced chemical reaction is as follows:
$2HCl\left(aq\right)+N{a}_{2}C{O}_3\left(aq\right)⟶2NaCl\left(aq\right)+C{O}_2\left(g\right)+H_{2}O\left(l\right)$
