Consider the following reactions. I. 2PbO + 4HCl to 2PbC l_2 + 2 H_2 O ll. PbO2 + 4HCl to PbC l_2 + + C l_2 +2 H_2 O Choose the correct statement.

Two planes P_1 and P_2 pass through origin. Two lines L_1 and L_2 also passingthrough origin are such that L_1 lies on P_1 but not on P_2, L_2 lies on P_2 but not on P_1 A,B, C are there points other than origin, then prove that the permutation [A', B', C'] of [A, B, C] exists. Such that: (a) A lies on L1, B lies on P1 not on L1, C does not lie on P1 . (b) A lies on L2, B lies on P2 not on L2, C' does not lies on P2.
