Question

1. Show the formation of magnesium chloride with the help of electron dot structure
2. What happens when
a. Zinc reacts with copper sulphate solution
b. Aluminium reacts with steam
c. Sodium reacts with water
Give balanced equations for each.​

Answer 1

when zinc reacts with copper sulphate zinc displaces copper as zinc is more reactive than copper

Answer 2

Answer:

(1) Zinc reacts with copper sulphate to give Zinc Sulphate

and copper metal.

CuSO4(aq) + Zn(s) - ZnSO4(aq) + Cu(s)

(ii) Magnesium reacts with HCI to give Magnesium

Chloride and hydrogen gas.

Mg(s) + 2HCI(aq) MgCl2 + H2(9)

(i) Sodium reacts with water to give Sodium Hydroxide

and hydrogen gas.

2Na(s) + 2H2001) - 2NaOH(aq) + H2(g)
