3. My car's hydrogen tank has a volume of 141 L. If the pressure in the tank when full is 5.25x105 torr at 25 °C, how many kg of hydrogen dose the tank hold?

i dont know

explanation:

it is stable as it is in group 0 which have full outer shells of electrons

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
