you have equal numbers of molecules of sodium chloride (NaCi), calcium choloride (CaCI2), potassium bicarbonated (KHCO3), and sucrose (C12H22)11). Which substance has an atom ratio of 1 to 2?

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 are the 4 phases of matter in order of increasing engery content?

Identify the correct mole ratio for each substance. sodium chloride (nacl) na: cl = 1: ammonium nitrate (nhno) h: o = 4:
