<p>If you're having trouble with chemistry i highly recommend Chemistry: the central science</p>
<p>there's alot of people who says it's basic, but trust me you will be able to grasp the concept and how to work out the problems quickly if you read that book. Pick up a cheap copy from half or amazon.</p>
<p>The widely used zumhadl (sp?) and chang is also good. </p>
<p>Petrucci is horrible. The diction is horrible. You literally need a phd in english to understand it. I mean so horrible that an old chemistry book published in 1970 was more helpful.</p>
<p>My gen chem class required petrucci, but i just couldn't understand it. I brought Chemistry: a molecular science by Moore. It's a really good book. The diction is student friendly. Plus he gives alot of example problems; in addition, he gives a strategy and explanation after ever example.</p>
<p>there's my suggestion. I think you're going thru what i'm going thru. The professor is of no help, and the book isn't the clearest. Just browse around in your local library or on amazon.</p>
