At high temperature, nitrogen combines with CaC2 to give : — s Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: When calcium carbide (CaC2) is heated with nitrogen gas (N2) at high temperatures (around 1000-1100°C), a reaction occurs. Step 2: The reaction is: CaC2 + N2 -> CaCN2 + C. The product CaCN2 is known as calcium cyanamide, and the mixture of CaCN2 and Carbon is called nitrolim. Step 3: Therefore, the nitrogen combines with calcium carbide to produce calcium cyanamide, which corresponds to option (b).
