There will be more...here's some...

1. Print and complete the following Ch 11 Review. The bolded questions on the back are topics we haven't discussed yet so you'll need to refer to your book. The rest you should be able to complete using mostly your brain (initially) and partly your notes (after you exhaust your brain). 2. The two FRQs we started in class - try the math, parts a & b for each. I've attached the answsers to part d for the large coal fired electric power plant... Try to answer it well first, then refer to the answer possibilities. Sorry period 2, we didn't start them in class. Here they are: ........................ A large, coal-fired electric power plant produces 12 million kilowatt-hours of electricity each day. Assume that an input of 10,000 BTU’s of heat is required to produce an output of 1 kilowatt-hour of electricity. a. Showing all steps in your calculations, determine the number of i. BTU’s of heat needed to generate the electricity produced by the power plant each day, ii. pounds of coal consumed by the power plant each day, assuming that one pound of coal yields 5,000 BTU’s of heat, iii. pounds of sulfur released by the power plant each day, assuming that the coal contains one percent sulfur by weight. b. The Environmental Protection Agency (EPA) standard for power plants such as this one is that no more than 1.2 pounds of sulfur be emitted per million BTU’s of heat generated. Using the results in part (a), determine whether the power plant meets the EPA standard. c. Describe two ways by which a fuel-burning electric power plant can reduce its sulfur emissions. d. Discuss why sulfur emissions from coal-fired power plants are considered an environmental problem and describe one negative effect on an ecosystem that has been associated with sulfur emissions. .......................... The Cobb family of Fremont is looking at ways to decrease their home water and energy usage. Their current electric hot-water heater raises the water temperature to 140°F, which requires 0.20 kWh/gallon at a cost of $0.10/kWh. Each person in the family of four showers once a day for an average of 10 minutes per shower. The shower has a flow rate of 5.0 gallons per minute. a. Calculate the following. Be sure to show all your work and include units with your answers. i. The total amount of water that the family uses per year for taking showers ii. The annual cost of the electricity for the family showers, assuming that 2.5 gallons per minute of the water used is from the hot-water heater b. The family is considering replacing their current hot-water heater with a new energy-efficient hot-water heater that costs $1,000 and uses half the energy that their current hot-water heater uses. How many days would it take for the new hot-water heater to recover the $1,000 initial cost? c. Describe TWO practical measures that the family could take that would reduce their overall water use at home. d. Describe TWO conservation measures (other than reducing hot water use) that the family could take to reduce the total amount of energy that they use at home. ............................ 3. Answer the questions below.
