If the reaction to form water were written h2(g)+12o2(g)→h2o(g), would you expect the same value of δh as in equation 2h2(g)+o2(g)⟶2h2o(g)δh=−483.6kj?

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.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
