How many grams of ammonia, NH3, are produced in the reaction with 50.0 g of N2, nitrogen, in Problem 2?

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

thats a little if u want the answer just look it up on google thats what i do haha : )
