Question

If 4.82 x 10^22 molecules of C4H10 were converted to CO2 and water as shown below, what is the enthaply chage for this process?

5. If 4.82 x 10” molecules of CHjo were converted to CO2 and water as shown below, what is the enthalpy change for the process? Show all work with the factor label method, including cancellation of units for each step. This problem must be correct to pass, but one minor rounding or sig fig error is allowed. C4H10(g) + 13/2 02(g) → 4 CO2(g) + 5 H2O(g) AH° = -1895 kJ

Answer 1
