BLM 5.1a, 5.1b. Chemicals and chemical Change. CHEMISTRY. – is the study of matter, its changes and its properties. MATTER. – is anything that has mass and takes up space. ATOM. – the smallest particle of matter. Solution Preparation. How do we create chemical solutions in a laboratory setting with a certain concentration/molarity? . Obtain the mass of the chemical compound serving as solute. Dissolve the solute in a small amount of the solvent. http://www.youtube.com/watch?v=F54rqDh2mWA. Chemical Change v. Physical Change. Chemical Change . Break or form chemical bonds. Molecular formulas of the products are NOT exactly the same as the reactants. . The taste of lemons and lime, the bite of sourdough bread, and the tang of a tomato are all caused by acids. Acids may be defined as substances that produce H. +. ions in solution.
