Last time we discussed oxygen as an element, including why we do not burst into flame in our 21% oxygen atmosphere. Quantum mechanics can really be interesting.
This time we shall discuss some of the compounds of oxygen with other elements, and I emphasize SOME because oxygen forms hundreds of thousands if not millions of compounds.
Some of these compounds are essential industrial materials, some are essential for biological processes, and some of them can cause real problems when released into the atmosphere. A few of them are quite toxic. Let us look into them!
