The chemical reaction between calcium carbide (CaC₂) and water (H₂O) produces calcium hydroxide (Ca(OH)₂) and acetylene gas (C₂H₂). The balanced chemical equation for this reaction is:
\[ \text{CaC}_2 + 2 , \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 + \text{C}_2\text{H}_2 \]
In this reaction, one mole of calcium carbide reacts with two moles of water to produce one mole of calcium hydroxide and one mole of acetylene gas.
