At STP, one mole of oxygen and one mole of neon contain equal numbers of A) atoms but the neon has a greater mass. B) atoms but the oxygen has a greater mass. C) particles but the neon has a greater mass. D) particles but the oxygen has a greater mass.

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.

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

Which of the following would have less momentum than a 52 kg cheetah running at 10 m/s?
