hi thanks for helping i was suppose to do this in class but didnt write the question down however started the answer I think that the question was '' why does carbon dioxide turns from a solid to a gas at -78.5 but magnesium oxide doesn't or magnesium oxide melts/turns into gas at a certain tempreture'' the question was similar to this but not exactly this. for the answer i need to include type of bond properties wheather it conducts electricity or not and similar things like that.
