This is a new study guide for chemistry. It's from 2019, and while the chapter on thermochemical equations (enthalpy, etc.) may differ from the current curriculum, the rest should be usable. The page in the third photo is a bit warped from water damage, but the other pages are clean. Please keep the above in mind, but otherwise, it should be perfectly usable as a reference book for exams. It will be placed in a plastic bag and shipped in an envelope.
