What size container is needed to hold 7.00 mol of a gas at 421 k and 153 kpa?

If a molecule with a molecular formula of c13h18 is treated with an excess of h2 in the presence of finally divided pt metal under conditions required for maximum hydrogenation of the molecule to give a molecule with a formula c13h24, how many rings are in the molecule?

Under which circumstances are kp and kc equal for the reaction aa(g)+bb(g)⇌cc(g)+dd(g)?

Draw the aromatic compound toluene (methylbenzene). show all hydrogen atoms, including those on the ring.
