Carbon monoxide (co) is toxic because it binds more strongly to the iron in hemoglobin (hb) than does oxygen (o2), as indicated by these approximate standard free-energy changes in blood:
reaction a: reaction b: hb+o2hb+co⟶⟶hbo2,hbco, δg∘=−70 kj/mol δg∘=−80 kj/mol
estimate the equilibrium constant k at 298 k for the equilibrium

hbo2+co⇌hbco+o2

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.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
