Calculate the volume in m3 of a balloon filled with 0.400 mol of hydrogen and gas temperature of 22.90 c and a pressure of 1.20pa

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?

What was bohr’s contribution to the planetary model

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
