Use the table below of enthalpies of formation to determine the heat of the following reaction.
Fe2O3(s) + 13CO(g)
-
2Fe(CO)5(g) + 3CO2(g)

FeO3(s)=-824.2
CO(g)=-110.52
Fe(CO)5(g)
CO2(g)=-393.51

the answer for sodium is 0.186

the answer for rubidium is 0.251

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.
