  2. BAn electron pair donor
  3. CA hydroxide ion donor
  4. DA proton (H⁺) donor
6.ふつう

How does evaporation differ from boiling?

  1. AEvaporation produces a solid, while boiling produces a gas
  2. BEvaporation happens only at the surface and at any temperature; boiling happens throughout the liquid at a set temperature
  3. CEvaporation happens throughout the liquid at a set temperature; boiling happens only at the surface
  4. DEvaporation needs a higher temperature than boiling
7.むずかしい

Raising the temperature by 10 °C can roughly double the rate of many reactions. What is the main reason?

  1. AMany more collisions have at least the activation energy
  2. BThe activation energy itself is lowered by the extra heat
  3. CThe particles become larger and easier to hit
  4. DThe reaction becomes more exothermic
8.むずかしい

An unknown element is shiny, conducts electricity, and reacts vigorously with water to form a basic solution and hydrogen gas. In which group is it most likely?

  1. AGroup 1 (alkali metals)
  2. BGroup 18 (noble gases)
  3. CGroup 14 (carbon group)
  4. DGroup 17 (halogens)
