What is the pH and poH of a solution made by adding water to 25 grams
of hydroiodic acid (HI) until the volume of the solution is 1500 mL?

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.

What volume would 2.25 moles of ne has occupy at stp?
