High School Chemistry Worksheets and Answer Keys, Study Guides and Vocabulary Sets.
CHEMISTRY is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy. The five main branches of chemistry include analytical chemistry, physical chemistry, organic chemistry, inorganic chemistry and biochemistry.
Atoms
Worksheets: 3Vocabulary: 2 Chemical Equations, Rates and Reactions
Chemical reaction is a process in which one or more substances, are converted to one or more different products. Synthesis - a chemical reaction where two or more elements or compounds combine to form a single product. Single Replacement Reaction - a chemical reaction where a more active element replaces a less active element in a compound. Decomposition - a chemical reaction in which a compound is broken down into simpler compounds or elements. Read more...iWorksheets: 6Vocabulary: 3 Chemical Formulas, Mixtures and Compounds

Matter in the solid state has a fixed volume and shape, with component particles (atoms, molecules or ions) close together and fixed into place. Matter in the liquid state has a fixed volume, but has a variable shape that adapts to fit its container. Its particles are close together but move freely. Matter in the gaseous state has both variable volume and shape, adapting both to fit its container. Its particles are neither close together nor fixed in place. Matter in the plasma state has variable volume and shape. Read more...iWorksheets: 3 The Periodic Law
