How much heat is absorbed when 20.00 g of C(s)reacts in the presence of excess SO₂(g)to produce CS₂(l)and CO(g)according to the following chemical equation? 5 C(s)+ 2 SO₂(g)→ CS₂(l)+ 4 CO(g)ΔH° = +239.9 kJ

Question

The reaction shows that 5 moles of C(s) react to absorb 239.9 kJ of heat. For 20.00 g of C(s), which is 20.00 g / 12.01 g/mol (molar mass of carbon) = 1.666 moles of C, the heat absorbed is (239.9 kJ / 5 moles) * 1.666 moles = 79.97 kJ.
