Chemical formulae and equations are part of the language of chemistry. In this book you will see how chemical compounds are represented as chemical formulae and how these formulae can be used to write balanced equations to describe chemical reactions. It includes an interactive activity with more than 150 equations for you to balance – this is an area where practice really does make perfect. You will then see how balanced chemical equations can be used in calculations such as working out the quantities of reactants and products in a reaction – a key skill for any experimental chemist. A student at A-level, International Baccalaureate, or K-12 level will be stretched by this content and teaching. If in doubt, download the free sample.
