4 for chlorine that the molecular mass is 102 but with 35 isotope and 37 isotope i think t sums to 100 instead. Any questions that appear on them are from topics like group 7 , redox or equilibria. MgO is better than using NaOH to treat acid in rivers and the stomach as it is only sparing soluble and weakly alkaline. Thanks a lot for all these notes, they are fantastic, especially when dealing with some of the tougher questions which are appearing on this new specification. It is possible i have missed something already in your notes, however i did not come across it. But I completely lost with year2 inorganic and transition metals, specially the new spec, I don’t even know the compounds that I need to know about? Please Sir I really hope you will read my comment and do the summary before May.
I think you should know everything on the guides. I would suggest going through the guides with a copy of the syllabus to hand so you can be sure why you the things are there. They often combine heats of combustion and formation in the same question to confuse people and see if they really understand what they are doing. I suggest you look again and try to undo your confusion. Definitions for other exam boards are slightly different and definitely exclude Scandium. I’m a bit confused on the question on page 5 of the equilibria pack. I was able to follow untill you wrote 0.
I’ve no clue how you got it since it should just be a simple rearrangement? I think this is a brilliant resource and thank-you so much for taking the time to create it. I was wondering if there are similar compact revision notes for Physics or Biology? Pingback: So you want to get into medical school? You are commenting using your Twitter account.

They did this through mixing, grinding, filtering, percolating, heating, and distilling, which led to preparations of vinegars, extracts, infusions, elixirs, syrups, tinctures, ointments, and pills. Today’s compounding pharmacy practice includes sterile preparations and nonsterile preparations. Sterile preparations typically include injections, infusions, and some irrigation, ophthalmic, and inhalation preparations. Nonsterile preparations typically include oral suspensions, topical solutions, topical suspensions, topical gels, powders, ointments, creams, emulsions, suppositories, and others. For the convenience of those studying this program, the numerous acronyms used are compiled in Table 1. BRIEF HISTORY OF STERILE COMPOUNDING Sterile compounding evolved primarily in hospitals in the 1960s and 1970s. IV compounding rooms, and work practices to support aseptic compounding.
States have jurisdiction over the practices of medicine and pharmacy. The practice of compounding has traditionally been regulated by individual state pharmacy and other health professional practice laws, and enforced by state boards of pharmacy. 64 people and illnesses in more than 800 people.
