Calcium carbide, CaC2, is manufactured by reducing lime with carbon at high temperature. (The carbide is used in turn to make ac

The energy of the carbide released is 7262.5MJ.

<h3>What is the energy?</h3>

We know that the reaction between calcium oxide and carbon occurs in accordance with the reaction; $CaO(s)+3C(s)----- > CaC_{2} (s)+CO(g)$ . The reaction is seen to produce 464.8kJ of energy per mole of carbide produced.

Number of moles of $CaC_{2}$ produced = 1000 * 10^3 g/64 g/mol

= 15625 moles of calcium carbide

If 1 mole of $CaC_{2}$ transfers 464.8 * 10^3 J

15625 moles of calcium carbide transfers 15625 moles * 464.8 * 10^3 J/ 1 mol

= 7262.5MJ
