A balloon filled with helium gas is found to take 4.7 hours to deflate to 55% of its original volume. How long (in hr) will it take for an identical balloon filled with the same volume of hydrogen gas (instead of helium) to decrease its volume by 55%?

_______hr

A explanation would be helpful

A) What pressure would it take to compress 150. L of helium gas initially at 1.00 atm into a 2.00 L tank at constant temperature?

Express your answer with the appropriate units.

B)A balloon filled with 2.00 L of helium initially at 1.55 atm of pressure rises into the atmosphere. When the surrounding pressure reaches 490. mmHg, the balloon will burst. If 1 atm = 760. mmHg, what volume will the balloon occupy in the instant before it bursts?
Express your answer with the appropriate units.


A balloon is filled with hydrogen gas and produces the followingchemical reaction between iron and sulfuric acid: Fe(s) + H2SO4(aq)--> FeSO4 (aq) + H2(g). If the balloon had a volume of 4800cubic meters and was filled to a pressure of 1 atm at a temperatureof 0 degrees C, a) what mass of iron (in kg) and how many moles ofsulfuric acid were required to fill it? b) If the total mass thatcan be lifted by a balloon is equal to the difference between themass of gas in the balloon and the mass of air displaced by theballoon, how much mass could by lifted by this balloon and how muchmass could the same balloon lift if it was filled with helium atthe same pressure and temperature. c) using the barometric formulaP= P(initial)e^(-mgh/kt) to estimate the height to which theballoon with a payload of 1000kg can rise when filled withhydrogen. (The balloon will rise until its density equals that ofthe surrounding air) Assume the the temperature of the air does notchange with the altitude. Use an average molar mass for the airbased on 80% N2, 20% O2.
