Question:

Translate the following statements into chemical equations and then balance them.

(a) Hydrogen gas combines with nitrogen to form ammonia.
(b) Hydrogen sulphide gas burns in air to give water and sulpur dioxide.
(c) Barium chloride reacts with aluminium sulphate to give aluminium chloride and a precipitate of barium sulphate.
(d) Potassium metal reacts with water to give potassium hydroxide and hydrogen gas.

Answer:

(a) Hydrogen gas combines with nitrogen to form ammonia

         H2                   +      N2               ---------→              NH3

Hydrogen gas          nitrogen gas                          Ammonia

       3H2                    +       N2              -----------→              3NH3
   Hydrogen  gas            NItrogen gas                                Ammonia
        

(b)   Hydrogen sulphide gas burns in air to give water and sulpur dioxide

        H2S(g)                                +           O2(g)                    ----------------→        H2O(l)     +     SO2(g)
      Hydrogen sulphide gas           Oxygen (from air)                                      water          Sulpur dioxide

       2H2S(g)                               +          3O2(g)                    --------------→         2H2O(l)     +     2SO2(g)


(c)    Barium chloride reacts with aluminium sulphate to give aluminium chloride and a precipitate of barium sulphate

        BaCl2(aq)               +            Al2(SO4)3(aq)                --------→         AlCl3(aq)                        +                  BaSO4(s)

      Barium chloride                Aluminium sulphate                       Aluminium chloride                      Barium sulphate

        3BaCl2(aq)               +            Al2(SO4)3(aq)                -------→          2AlCl3(aq)                     +                   3BaSO4(s)

     
(d)  Potassium metal reacts with water to give potassium hydroxide and hydrogen gas

       K(s)           +     H2O(l)       -----→              KOH(aq)                   +             H2(g)

     Potassium         Water              potassium hydroxide                 hydrogen gas

       2K(s)           +  2H2O(l)   ------- →       2KOH(q)                         +               H2(g)
