  1. AEvery substance dissolves in water
  2. BOnly substances with identical formulas can ever dissolve in each other
  3. CSolids dissolve only in other solids
  4. DPolar solvents dissolve polar substances, and nonpolar solvents dissolve nonpolar ones

  1. AStrong bonds formed by transferring electrons
  2. BAttractions between a hydrogen atom and a metal ion
  3. CWeak, temporary attractions caused by shifting electrons in molecules

  1. A600 mmHg
  2. B760 mmHg
  3. C253 mmHg
  4. D750 mmHg
6.ふつう

貴ガスがほとんど反応しないのはなぜか。

  1. A電子がまったくないから
  2. Bすべて放射性だから
  3. C最外殻がすでに電子で満たされているから
  4. D原子が他の原子よりずっと大きいから
7.むずかしい

Why is it easier to remove the outer electron from a potassium atom than from a lithium atom?

  1. ALithium has more electron shells than potassium
  2. BPotassium has fewer protons, so its nucleus pulls much more weakly on every electron
  3. CPotassium's outer electron is in a full shell
  4. DPotassium's outer electron is farther from the nucleus and more shielded by inner electrons
8.むずかしい

A salt is dissolved in water in an insulated cup, and the water temperature falls from 25 °C to 20 °C. Which statement is correct?

  1. ADissolving is endothermic; the water took heat from the salt
  2. BDissolving is endothermic; the dissolving salt took heat from the water
  3. CNo energy change occurred, because the temperature fell
  4. DDissolving is exothermic; the dissolving salt released heat into the water
