Chemistry Homework help? If some of the product contained magnesium nitrate rather than magnesium oxide, would the expermiental percentage Mg be higher or lower than that expected for pure magnesium oxide. Suppose there is three 1.000 g samples of magnesium. Suppose you heat one sample of magnesium in pure oxygen so that it is completely converted to magnesium oxide (with no worries about magnesium nitride being present. What is the % Mg in this product? Suppose you heat another sample of magnesium in pure nitrogen to completely convert it to magnesium nitride. What would be the % Mg in this product? Suppose you heat the third sample in air which is a mixture of magnesium and oxygen, and find that the product is mostly magnesium oxide, but
