Why does water boil at a lower temperature at the top of a high mountain?

  1. AThe air pressure is lower, so less vapour pressure is needed to boil
  2. BGravity is weaker, so the molecules escape more easily
  3. CThe air is colder, so the water loses heat and boils sooner
  4. DThere is less oxygen dissolved in the water up there
6.ふつう

  1. AIt has no effect on the boiling point
  2. BIt lowers the boiling point slightly
  3. CIt raises the boiling point slightly
  4. DIt makes the water boil at room temperature
7.むずかしい

A catalyst is added to an exothermic reaction. How does the energy diagram change?

  1. AThe reaction becomes endothermic
  2. BThe products end up at a lower energy, so more heat is released
  3. CThe reactants start at a higher energy
  4. DThe peak is lower, but the energy of reactants and products stays the same
8.むずかしい

Zinc reacts as Zn + 2HCl → ZnCl₂ + H₂. What mass of zinc (65 g/mol) reacts completely with 50 mL of 2 M HCl?
