Question

Write the balanced equation for the The action of water on Calcium carbide

Answer 1

• A balanced chemical equation has equal numbers of atoms for each element involved in the reaction and is represented on the reactant and product sides.
• The action of water on calcium carbide $\left({\mathrm{CaC}}_2\right)$produces Calcium hydroxide $\left(\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\right)$ and Ethyne $\left({\mathrm{C}}_2{\mathrm{H}}_2\right)$ as products.
• Ethyne is a colorless gas with an ether-like odor (acetylene gas) and the reaction is exothermic in nature.
• Balanced equation is as follows.

$\underset{\mathrm{Calcium}\mathrm{hydroxide}}{{\mathrm{CaC}}_2\left(\mathrm{s}\right)}+\underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\to \underset{\mathrm{Calcium}\mathrm{hyroxide}}{\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\left(\mathrm{s}\right)}+\underset{\mathrm{Ethyne}}{{\mathrm{C}}_2{\mathrm{H}}_{2\left(\mathrm{g}\right)}}$
