This updated edition of the established bestselling title for standard grade chemistry is now in full colour throughout. It remains the only text specifically written to match the requirements of standard grade, and provides clear coverage of General and Credit level material. The authors have revised each chapter taking account of new developments, such as in the field of fossil fuels. Other chapters have been updated where relevant, for instance to reflect changes to the Relative Atomic Mass data. The chemical dictionary chapter has been enlarged to include more key words. New and up to date exam questions have been included, together with homework and whole course questions at the end of the book. This edition includes answers to all the questions in the text; a without answers version is also available.
