Answer 1

Answer #1

Co+3 and SO4-2 are forming compound here.

While writing formula of ionic compounds:

Charge of cation becomes subscript of anion

Charge of anion becomes subscript of cation

So, Co+3 and SO4-2 will form

Co2(SO4)3

Here are 2 Co+3 and 3 SO4-2

Answer: 2

Answer 2

To determine the salt formed during a neutralization reaction, combine the anion formed by the dissociation of the acid and the cation formed by the dissociation of the base in a ratio that results in a neutral, ionic compound. For example, if you have a cation with a 1+ charge and an anion with a 2- charge, you will need two cations to balance the charge. [(1+ charge on cation)(2)]+[2 - charge on anion)(1)] = (+2) + (-2) = 0...
