The net charge on a sulfide ion (S2–) is –2. Explain how this ion obtains its charge. Your answer should include a discussion of subatomic particles (HINT: electrons).

if you're asking what comes out, it's steam.

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.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
