Are the physical and chemical properties of the components of a mixture changed when mixed together?

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.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

answer carbon and three oxygen atoms;
