You have a balloon containing 1 L of air at 1 atm and 273 K in a vacuum chamber. What will the volume of the balloon be when you reduce the pressure to 0.5 atm and
increase the temperature to 373 K? (Use the combined gas law P1V /T1 = P2V2/T2.)

Can anyone (a-level) a student was analysing a carbonate compound, mco3, containing an unknown group 2 metal, m. the student carried out thermal decomposition on 0.730g of the carbonate and measured the volume of gas produced. mco3 (s) mo (s) + co2 (g) the student collected and measured 120cm3 of carbon dioxide. 1 mol of carbon dioxide occupies 24 000 cm3 under these conditions. calculate the molar mass of the group 2 carbonate and hence deduce the identity of the group 2 metal, m.
