When carbon disulfide is formed from its elements, heat is absorbed. calculate the amount of heat in (kj) absorbed when 5.66g of carbon disulfide is formed

6.64 KJ.

Explanation:

For the reaction:

C + 2S → CS₂,

The amount of heat absorbed when 1.0 mol of CS₂ is formed = 89.3 kJ.The no. of moles of 5.66 g that formed of CS₂ = mass / molar mass = (5.66 g) / (76.143 g/mol) = 0.0743 mol.The amount of heat in (kJ) absorbed when 5.66g of carbon disulfide is formed = n x The amount of heat absorbed when 1.0 mol of CS₂ is formed = (0.0743 mol) (89.3 kJ/mol) = 6.64 KJ.
