In today’s experiment, a combination reaction of magnesium and oxygen is used to determine the empirical formula ofmagnesium oxide. After the experiment, I need to answer the fellow two questions: #1; There is one major competitive side reaction that may reduce the accuracy of your results in this experiment. Consult the Internet to research, describe and write a balanced equation for this side reaction. (HINT: What component of air other than oxygen could be responsible?) #2; My Professor asked me match are empirical formula of magnesium oxide from my experiment with the actually one by searching it on the internet. My empirical formula of magnesium oxide from my experiment is Mg4O3 and I look up on the internet is MgO. So, I have to find out why they are different Please help me question #1,2 thank you very much
