Question

One mole of BaCf ionises completely, total moles of barium and chloride ions will be:
(A) 1 mole
(B) 2 moles
(C) 3 moles
(D) 02 x 1023 moles

Answer 1

Answer:

2 moles

Explanation:

BaCl ---> Ba+. + Cl -

for 1 mole of BaCl 1mole of Ba+ and 1mole of Cl- will be produced.

Answer 2

Answer:

(C) 3 moles

Explanation:

Since we have given that the reactant is barium chloride is $BaCl_{2}$ which is a ionic compound.

When ionic compound decomposed then it gives cation and anion.

$BaCl_{2}$ is a ionic compound and it gives barium and chloride ions on decomposition.

Decomposition reaction of Barium chloride is,

$BaCl_{2} \rightarrow Ba^{2+}  + 2Cl^{-1}$

So, 3 moles is correct answer and option (C) is correct.
