Write the balanced chemical equation for the preparation of Ethyne using Calcium carbide

About Ethyne ($C_2{H}_2$):

1. The first member of the alkyne is Ethyne (Acetylene) $C_2{H}_2$ with two carbon atoms bonded by a triple bond.
2. The molecular formula of Ethyne is $C_2{H}_2$
3. The structural formula of Ethyne: $H-C\equiv C-H$
   

Formation of Ethyne using Calcium carbide

1. Calcium carbide ($Ca{C}_{\mathit{2}}$) reacts with water to give Ethyne $\left(C_2{H}_2\right)$ or Acetylene gas and Calcium hydroxide ($Ca{\left(OH\right)}_2$).
2. Acetylene $\left(C_2{H}_2\right)$ is basically a colorless gas.
3. The balanced chemical equation for the preparation of Ethyne using Calcium carbide is as follows:

$\underset{\mathrm{Calcium}\mathrm{carbide}}{{\mathrm{CaC}}_2\left(\mathrm{s}\right)}+\underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}}\left(\mathrm{l}\right)\to \underset{\mathrm{Acetylene}\mathrm{gas}}{{\mathrm{C}}_2{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{calcium}\mathrm{hydroxide}}{\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\left(\mathrm{aq}\right)}$
