Change the following in to chemical equations and balance them.
a) Hydrogen gas combines with nitrogen to form ammonia.
b) Potassium reacts with water to give potassium hydroxide and hydrogen gas.
c) Aluminium metal reacts with ferric oxide giving aluminium oxide and iron.
d) Ferric oxide reacts with aluminum metal to form aluminum oxide and iron.
e) Barium hydroxide reacts with hydrogen bromide to give barium bromide and water.
f) Calcium carbonate on heating gives calcium oxide and carbon dioxide.

The answer to your question is below

Explanation:

I just write the formulas of the reactants and products and balanced the reactions.

a)

          3H₂(g)  +  N₂(g)   ⇒   2NH₃

b)

          2K  +  2H₂O  ⇒   2KOH  +  H₂ (g)

c)

         2Al(s)   +  Fe₂O₃  ⇒   Al₂O₃  +  2Fe

d)

         Fe₂O₃  +  2Al   ⇒  Al₂O₃  +  2Fe

e)

         Ba(OH)₂  +  2HBr   ⇒   BaBr₂  +  2H₂O

f)

         CaCO₃  + Δ ⇒  CaO  + CO₂

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
