   2. __________ _____ Given that P = iV, calculate the power P for the dryer.
   3. __________ Power is now forty cents per kiloWatt hour, or $0.40 for 1000 Watts for one hour. How much does it cost to run the dryer for one hour?
9. 1. __________ What is the atomic number of Zn?
   2. __________ What is the atomic mass of Zn?
   3. __________ How many protons does Zn have?
   4. __________ How many neutrons does Zn have?
   5. __________ How many electrons does Zn have?
10. [Note that in an atom the number of neutrons is equal to or greater than the number of protons. Thus the more numerous nucleons are the neutrons.]
