Write down the equations of chemical reactions according to the descriptions, indicate the type of reactions: 1. Chlorine interacts with sodium to form sodium chloride 2. When water and potassium interact, hydrogen and potassium hydroxide are formed 3. Barium chloride reacts with silver nitrate, thus forming silver chloride and barium nitrate.
1) 2Na + Cl2 = 2NaCl (compound reaction)
2) 2K + 2H2O = 2KOH + H2 (substitution reaction)
3) BaCl2 + 2AgNO3 = 2AgCl + Ba (NO3) 2 (exchange reaction)
