3. MnO4- + 5e- + 8H+ ⇒ Mn2+ + 4H2O

4. F2 ⇒ 2F- + 2e-

ans A

hi,

the answer is d.indefinite shape but definite volume, let go oogle u out

hope this !

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.
