Three closed vessels A,B and C are at the same temperature T and contain gases which obey the Maxwellian distribution of velocities. The vessel A contains only O2, B only N2 and C a mixture of equal quantities of O2 and N2. If the average speed of the N2 molecules in vessel B is V2 and that of oxygen molecules in A is V1, the average speed of N2 molecules in C is? A

Gold reacts with chlorine at 150oC as per balanced chemical equation, 2Au+3Cl2→2AuCl3. 10g of each gold and chlorine are sealed in a container and heated at 150oC till the reaction is complete. Name the limiting and excess reactants. Also calculate the amount of AuCl3 formed and mass of excess reactant left behind. (Atomic masses Au=196.97u and Cl=35.5u).
