Chemistry can be one of the more difficult subjects in school, mainly because memorization is crucial. It can be hard to memorize tons of facts and equations. A chemistry equations and answers guide does help students; some more than others. You can refer to the study guide to determine which formula is suitable to use for the question at hand. The more savvy student might consider one or more ways to creatively benefit from the guide. For example, creating useful "tricks" to aid you during a challenging test or quiz. Chemistry may seem difficult, but there are useful study methods.
