Chapter 8, Problem 8.57UTC
A balloon is filled with helium gas with a partial pressure of 1.00 atm and neon gas with a partial pressure of 0.50 atm. For each of the following changes (ato e) of the initial balloon, select the diagram (A, B, or C) that shows the final volume of the balloon: (8.2, 8.3, 8.6)
- The balloon is put in a cold storage unit (P and n do not change).
- The balloon floats to a higher altitude where the pressure is less (n and T do not change).
- All of the neon gas is removed (T and P do not change).
- The Kelvin temperature doubles and half of the gas atoms leak out (P does not change).

Consider these reactions:
Reaction 1: H 2 (g)+Cl 2 (g) longrightarrow 2HCl(g) Delta*H = - 184.6kJ
Reaction 2: 2OF 2 (g) longrightarrow O_{2}(g) + 2F_{2}(g) Delta*H = - 49.4kJ
Reaction 3: N 2 (g)+2O 2 (g) longrightarrow 2N*O_{2}(g) Delta*H = 66.4kJ
Use Reaction 3.

Holiday cookies rise (get bigger) when baked in the oven at 350oF because:
a. sodium aluminum phosphate (Na Al PO4) releases an acid that forms CO2 gas from sodium bicarbonate (Na+ HCO3-)
b. the Maillard reaction hydrolyzes wheat gluten in the batter
c. yeast ferment sugar (sucrose) in the batter to form CO2 at temperatures above 72oC
d. oxygen (O2) is needed to support the growth of lactic acid bacteria added to the batter
e. the amount of sucrose sugar added to Holiday cookies could make reindeer fly
