The three types of intermolecular forces have different strengths. Rank them from weakest to strongest.

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.

Joan writes four numbers on the board in standard form, and then she writes their scientific notation

How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?
