Two standard scuba tanks are filled to 200 atm—the first with a volume of 14.2 L and the second with 11.4 L. Assume that the tank regulator delivers 1.5 L of air at 1 atm for each breath. How many breaths could each different tank supply if one used the contents of each tank completely? Hint: P1V1 = P2V2*Breaths Tank 1=? Tank 2=? 2. Methane CH is a simple organic molecule that is used as a fuel—it is the major component of natural gas. The bottom of the ocean contains large amounts of methane hydrate (also called methane ice or methane clathrate), enough that it has been suggested as a major source of fuel. The methane hydrate contains 6 moles water for each mole of methane. What percentage of methane hydrate is methane? What percentage is water? 3. ______________ solids are made up of large numbers of independent, constituent units, some of which attract and others repel. 4. ______________ solids have large numbers of covalent bonds, but not necessarily many component units. 5. What is the respiration rate for a breath every 2.5 seconds?
