Step 1: Identify calcium carbide and its primary reaction. Calcium carbide is an ionic compound with the chemical formula CaC_2. It is primarily known for its reaction with water to produce acetylene gas. Step 2: Write the balanced chemical equation for the reaction of calcium carbide with water. When calcium carbide reacts with water, it produces acetylene gas (C_2H_2) and calcium hydroxide (Ca(OH)_2). CaC_2(s) + 2H_2O(l) C_2H_2(g) + Ca(OH)_2(aq) Step 3: Explain the significance of the product and its storage. The acetylene gas produced is highly flammable and unstable when pure, especially under pressure. For safe storage and transport, it is usually dissolved in a solvent like propanone (acetone) and kept in steel cylinders at high pressure, typically around 17 atmospheres. This method prevents the gas from decomposing explosively. The key objective, calcium carbide, is therefore crucial for the industrial production of acetylene, which is then stored as described in the preceding text. Send me the next one 📸
