Answer:
wait i send you answers
Explanation:
a.) Hydrogen gas combines with nitrogen gas to form ammonia gas.
When hydrogen gas combines with nitrogen to form Ammonia the following chemical reaction will take place. Our equilibrium reaction will be N2(g) + 3H2(g) ⇔ 2NH3(g) + Heat. In this case, Hydrogen and nitrogen react together to form ammonia.
b.) Hydrogen sulphide gas burns in air to give water and sulphur dioxide gas.
answer is in the picture
c.) Barium chloride reacts with aluminium sulphate to give aluminium
) Barium chloride reacts with aluminium sulphate to give aluminiumchloride and a precipitate of barium sulphate
The question given to us is Barium chloride when reacting with aluminium sulphate produces aluminium chloride and a barium sulphate precipitate. Al2(SO4)3 + 3BaCl2 ------> 2AlCl3 + 3BaSO4.
