Chapter 2, Problem 47Q

One mechanism that helps break down ozone in the Antarctic region involves the BrO• free radical. Once formed, it reacts with ClO• to form BrCl and O2. BrCl, in turn, reacts with sunlight to break into Cl• and Br•, both of which react with O3 and form O2.

  1. a. Represent this information with a set of equations.
  2. b. What is the net equation for this cycle?

4. Carbon Monoxide is the most common air pollutant. a. How is it formed? b. What are its health impacts?
Warming of the atmosphere is due to the greenhouse effect. What is responsible for this phenomenon? a. The CO2 level in the atmosphere is increased b. The global temperature is decreased tremendously c. There is a widespread destruction on the green color of plants. d. The amount of oxygen in the atmosphere is greatly affected.
6. How do airbags work? a. The rapid decomposition of sodium azide, NaN3 (MW = 65.0099 g/mol), to its elements is the first of several reactions used to inflate airbags. How many moles of gas are produced from 60.0 g of NaN3? Note: You will need a balanced chemical equation. b. As you know solid sodium is highly reactive (and we probably don't want it on our face in a car accident), the following reaction removes the solid sodium. How many moles of N₂ are produced in this reaction? Hint: You will need the number of moles of Na formed in the first reaction (part a). Na(s) + KNO3(s) → K₂O(s) + Na₂O(s) + N₂(g) c. If the overall process (both reactions) is 84.5 % efficient, how many moles of nitrogen gas are actually produced? d. What pressure must a 60.0 L air bag be at for the actual amount of nitrogen gas produced (answer in 6c) to inflate it at 25°C? e. What would the volume of the airbag be if an accident were to occur at a much lower temperature (the average winter temperature in…
