Can you recommend an easily accessed site for chemistry topics for engineers. (Preferrably with topics of crystallization and inorganic chemistry)
Ny experience is that a number of universities have sites run by professors there but generally those sites are accessed by specific topic and not by a full course. You can Google "Chem Team" and get good information. Or you can post your question on Jiskha. Often we can find a good site as a reference for you.
Here is the chemteam URL for the main menu.
