Due to a significant difference between the 5th and 6th IEs, it can be deduced that X is in Group V of the periodic table with charge -3. It will mst probably form a covalent chloride XCl3.
28. B
Dissolving occurs due to hydrogen bonding between hydrogens or its isotopes that are directly bonded to oxygen, nitrogen or flourine, with water molecules. In this case, hydrogens directly bonded to oxygen are to be replaced, so apparently there would be 3 replacements.
3. C
At room temperature, post reaction gases are unreacted O2, CO2 and SO2. No need to take molar ratios, gaseus ratios are taken. 30 cm3 of O2 is left after reacton (30 cm3 reacts with 10cm3 of the thiol), 10 cm3 each of SO2 and CO2 are produced. Total is 50 cm3.
