Hq5.49 use standard enthalpies of formation to calculate the standard enthalpy of reaction for the following reaction: 2 h 2 s(g) + 3 o 2 (g) → 2 h 2 o(l) + 2 so 2 (g) δh ∘ rxn

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.
