Summary

Homework Helpers: Chemistryis a user-friendly review book that will make every student--or parent trying to help their child feel like he or she has a private Chemistry tutor. Concepts are explained in clear, easy-to-understand language, and problems are worked out with step-by-step methods that are easy to follow. Each lesson comes with numerous review questions and answer keynotes that explain each correct answer and why it's correct. This book covers all of the topics in a typical one-year Chemistry curriculum, including: '¢ A systematic approach to problem solving, conversions, and the use of units. '¢ Naming compounds, writing formulas, and balancing chemical equations. '¢ Gas laws, chemical kinetics, acids and bases, electrochemistry, and more. WhileHomework Helpers: Chemistryis an excellent review for any standardized Chemistry test, including the SAT-II, its real value is in providing support and guidance during the year's entire course of study.
