Question

What happens when
a. Zinc reacts with copper sulphate solution
b. Aluminum reacts with steam
c. Sodium reacts with water
Give balanced equations for each.

Answer 1

Answer:

1. When a zinc strip is dipped into a copper sulphate solution ; Zinc displaces Copper from its Sulphate Solution Zn(s) + CuSO4(aq) -> Cu(s) + ZnSO4 (aq)....
2. aluminium reacts with steam , it forms aluminium hydroxide and hydrogen gas is liberated . Aluminium forms a very strong oxide when reacted with normal water , but when steam is passed over aluminium , it forms aluminium hydroxide due to more energy being supplied to energy
3. whenSodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2) .
