Reaction of Aluminium metal with Water: Reaction of aluminium metal with cold water is too slow to come into notice. But when steam is passed over aluminium metal, aluminium oxide and hydrogen gas are produced. 2Al + 3H 2 O → Al 2 O 3 + 2H 2. Reaction of Zinc metal with Water: Zinc metal produces zinc oxide and hydrogen gas when steam is passed over it. Zinc does not react with cold water.

Sulfur trioxide (SO3) dissolves in and reacts with water …

Sulfur trioxide (SO 3) dissolves in and reacts with water to form an aqueous solution of sulfuric acid (H 2 SO 4).The vapor in equilibrium with the solution contains both SO and H 2 O. If enough SO 3 is added, all of the water reacts and the solution becomes pure H2S04. If still more SO 3 is added, it dissolves to form a solution of SO 3 in H2SO 4, called oleum or fuming sulfuric acid.
