barxatty [35]2 years ago
5 0

Explanation:

CaCl2 ⇄ Ca-²+2Cl-¹

1mole⇄1mole+2moles

So from above ..

1mole CaCl2 produce 1mole Ca-² & 2 moles of Cl-².

For 2.5 moles we multiply the above chemical eq. With 2.5

2.5CaCl2⇄2.5Ca-²+5Cl-¹

So from 2.5 moles of CaCl2 we get 2.5 mole calcium ion and 5 moles chloride ion…
