<span>1 mole = 6.022 X 10^23
0.5 mole = 0.5 x 6.022 x 10^23 = 3.011 x 10^23

Answer:
A violent reaction will occur and zinc sulphide is formed as a product
Answer:
The given statement is true.
Explanation:
Strong acids and bases act as strong electrolytes.They undergo complete dissociation in an aqueous medium to generate cations and anions.
For example HCl ⇄ H+ + Cl-
Hydrochloric acid is a strong electrolyte,it undergo complete dissociation in an aqueous solution to generate H+ ion and Cl- ion.
On the other hand acetic acid is a weak acid and act as weak electrolyte.In aqueous solution acetic acid under partial dissociation to form acetate anion and proton.
CH3COOH ⇄ CH3COO- + H+
