2.)
ClF3
3.)
ZnO
4.)
Au2S

#4 is the correct answer

Explanation:

For #1, Cobalt has an ionic charge of +2

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
