Question 1

Find ΔH° for the reaction C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(l).

ΔH° = -2046 kJ for the reaction: C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(g)

The heat of vaporization of water is 44.0 kJ/mol. Note that H2O is a liquid in the first reaction and a gas in the second.
◦ -2090 kJ
◦ -1870 kJ
◦ -2002 kJ
◦ -2222 kJ

Question 2

Coal gasification can be represented by the equation:
2 C(s) + 2 H2O(g) → CH4(g) + CO2(g)ΔH = ?

Use the following information to find ΔH for the reaction above.
CO(g) + H2(g) → C(s) + H2O(g)ΔH = -131 kJ
CO(g) + H2O(g) → CO2(g) + H2(g)ΔH = -41 kJ
CO(g) + 3 H2(g) → CH4(g) + H2O(g)ΔH = -206 kJ

◦ 116 kJ
◦ 15 kJ
◦ -372 kJ
◦ -116 kJ

Many people have small pouches in their colons that bulge outward through weak spots. Each pouch is called a diverticulum. About 10% of Americans older than age 40 years have diverticulosis, which, when the pouches become infected or inflamed, is called diverticulitis. The main cause of diverticular disease is a low-fiber diet.
