Ans: (C) 2022 Numerical Type JEE Advanced 2022 Paper 2 Online Q1. The reaction of ???? and ?? ?? ?? ?? gives a Xe compound ?? . The number of moles of ???? produced by the complete hydrolysis of ?? ?????? of ?? is Ans: 4 Xe + 2O 2 F 2 ? XeF 4 + 2O 2 (P) 6XeF 4 + 12H 2 O ? 4Xe + 2XeO 3 + 24HF + 3O 2 (P) So, from the above reaction, it is clear that 6 moles of XeF 4 produces 24 moles of HF. So, 1 mole of XeF 4 will produce 24 6 moles of HF, i.e., 4 moles of HF. Multiple Correct Type JEE Advanced 2022 Paper 1 Online Q2. The treatment of galena with ?????? ?? produces a gas that is A. paramagnetic B. bent in geometry C. an acidic oxide D. colorless Ans: (A,D) PbS + dil. HNO 3 ? Pb(NO 3 ) 2 + S + NO + H 2 ONO is paramagnetic due to the presence of unpaired electron. It is a neutral oxide. It is colourless. Hence, (A) and (D) are correct statements.Read More
