GIVING BRAINLISTED The image represents the reaction between a certain number of molecules of H2 and O2.

Two squares are shown. Inside the left square two units of two joint circles if shown. The molecular formula of hydrogen gas is shown on top of this square. The square on the right has three units of two joint circles. The molecular formula for oxygen gas is shown on top of this square

If the maximum amount of H2O is formed during the reaction, what is the leftover reactant?

One molecule of H2
Two molecules of H2
One molecule of O2
Two molecules of O2

one molecule of O2.

Explanation: sweet i just took a guess but I believe that if 3 o2 molecules - 2 h2 molecules I think that its just basic maths and it is C because 3-2 = 1 and its o2 remaining, sorry if I’m wrong.

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.
