A challenge gaining prominence throughout the planet is the increased need for "green" or sustainable energy. In certain parts of the country, wind farms are a viable alternative to conventional energy sources. An average wind turbine (the device which converts rotational motion to electricity) has a maximum capacity of 1.60 MW. However, realistically the wind turbine never runs at full power. If a wind turbine runs at 30.8% capacity for 1.00 year, how much energy does the wind turbine generate? An average American household consumes 1.10 times 10^4 kWh in 1.00 year. How many houses can the one wind turbine power?

The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (c3h8) to burn it completely. for every gram of propane that flows through the burner, what volume of air is needed to burn it completely? assume that the temperature of the burner is 195.0°c, the pressure is 1.05 atm, and the mole fraction of o2 in air is 0.210.
