Answer to Question #313306 in General Chemistry for Tans

Question

Consider the information above on the combustion of acetone. Solve

the following problem involving the Enthalpy of Chemical Reactions. Show your

solutions. You may refer to the lecture notes for sample problems.

Calculate the amount of heat released during the combustion of

a. 0.75 mole of C3H6O

b. 120g of C3H6O

Answer 1

Complete combustion of 1.00 mol of acetone (C3H6O) liberates 1790 kJ of heat:

C3H6O(l) + 4 O2(g) → 3 CO2(g) + 3 H2O(l); ΔH = -1790 kJ.
