Calculate the standard enthalpy change, in kJ mol–1, for the reaction between carbon disulfide, CS2, and oxygen shown in the following equation.

Calculate the standard enthalpy change, in kJ mol–1, for the reaction between carbon disulfide, CS2, and oxygen shown in the following equation. The Correct Answer and Explanation is: Sure! First, we need the balanced chemical equation for the combustion of carbon disulfide (CS₂) in oxygen: CS2(l)+3O2(g)→CO2(g)+2SO2(g)\text{CS}_2(l) + 3\text{O}_2(g) \rightarrow \text{CO}_2(g) + 2\text{SO}_2(g) Step 1: Use
