1. Consider the incomplete combustion reaction that you observed with the butane lighter: 

C4H10(g) + 5 O2(g) → 2 CO2(g) + 5 H2O(g) + CO(g) + C(s)

Assume that the butane is a gas at the time of combustion (it is, by the way). Assume that, at SATP, a mass of 0.01 g of butane is burned.

a. What mass of solid carbon is produced?

b. How many atoms is this?

2. During a collision, the aribag in a car will deploy and fill up with nitrogen gas. In order for this to occur, solid sodium azide (NaNa3) is ignited and decomposes to produce solid sodium (Na) and nitrogen (N2) gas.

1. Write the balanced equation for the decomposition of sodium azide.
2. If the airbag has a volume of 70.0 L, then what mass of soidum azide would be required to completely fill the airbag at a temperature of 295 K and atmospheric pressure of 101.2 kPa?

3. In a brief statement, describe a situation where knowledge of the ideal gas law and stoichiometric calculations are, or may be, used in a technological application.
