To keep with the law of conservation of matter, determine the correct product for the following reaction: pbcl2 (aq) + 2 ki (aq) → + a) pbi2 + kcl2 b) pbi2 + 2 kcl c) 2 pbi + kcl2 d) 2 pbi + 2 kcl

Both 1,2−dihydronaphthalene and 1,4−dihydronaphthalene may be selectively hydrogenated to 1,2,3,4−tetrahydronaphthalene. one of these isomers has a heat of hydrogenation of 101 kj/mol (24.1 kcal/mol), and the heat of hydrogenation of the other is 113 kj/mol (27.1 kcal/mol). match the heat of hydrogenation with the appropriate dihydronaphthalene.
