I have a physics question. This is for extra credit which I really need to earn- If I made a solar cell how would I know which material is best to use if given choices like aluminum with a work function of 4.1eV at a cost of 2.40Kg or platinum with a work...

If you produce 3.63 moles of Na2, how many moles of H2 was needed?

A sample of a gas (5.0 mol)at 1.0 atm is expanded at constant temperature from 10.0 L to 15 L. The final pressure is _______ atm.

A 5.00 liter sample of gas measured at 27 degrees Celcius and 1.25 atm of pressure has a mass of 10.13 grams. What is the molecular weight of the gas in u?

What is the landform of the Grand Teton?

Please explain how to solve this: (ã5 + 4)(ã5 - 1)

All the information is there but have to assume that he starts working at the beginning of the month…does not get his first check held back and all his bills are currently caught up. Also have to assume we are at the beginning of the month now and have al...

Thank you for directing me to that site-that one I didn't find while I was looking for info-I did confuse work force for work function- I appreciate you following up
