Given that the ΔH°combustion for hydrogen is -286 kJ/mol, how much heat is released when Ben blows up a balloon containing 56.5 g of hydrogen gas, H2?

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
