This might be a stupid question... but can anyone tell me the difference between Pure Substances and Mixtures?
I read the definition both in the book but when I look at my hwk problems they don't come to my head what's what. For example A metal that melts not fully at 300 degrees and fully melts at 440 degrees. I thought that it would be Pure substance because a compound is a pure substance. But its actually Homogeneous mixture.
Any help to help me understand the difference is appreciated
