Suppose a weather forecast reports that the probability of snow this week is 0.18. The forecast states that if it snows this week, the probability that it snows next week is 0.29. If it does not snow this week, the probability that it snows next week is 0.12. The tree diagram depicts the possible weather event outcomes with the associated probabilities.

6) A student late to class runs at a constant 4.30 m/s to catch a bus. She reaches the bus stop 2.00 s after the bus starts from rest with an acceleration of 0.950 m/s2. Where and when does the student catch the bus?

Certain 16e metal hydrides catalytically convert free 1-butene to free 2-butene 

Use Henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.2 L of water upon warming from 25 "C to 50 C. Assume that the water is initially saturated with nitrogen and oxygen gas at 25 C and a total pressure of 1.0 atm. Assume that the gas bubbles out at a temperature of 50 ° C. The solubility of oxygen gas at 50 ° C' is 27.8 mg /L at an oxygen pressure of 1.00 atm. The solubility of nitrogen gas at 50 * C is 14.6 mg /L at a nitrogen pressure of 1.00 atm. Assume that the air above the water contains an oxygen partial pressure of 0.21 atm and a nitrogen partial pressure of 0.78 atm.
