State Standards. CLE.3203.1.9 – Apply the Laws of Conservation of Mass/Energy to balance chemical equations. I can identify the products and reactants in a chemical reaction.. I can state the law of conservation of matter.. I can determine the number of each atom in a compound based on subscripts and coefficients.. Parts of a chemical equation:. Reactants. : a substance present at the beginning of a chemical reaction. (Left side). Products. : a substance that is produced during a chemical reaction (Right Side). By: Abby . Marstiller. , Paulina . Pullin. , Emily . Henline. What is a chemical reaction?. A chemical reaction involves the making or breaking of bonds between atoms. . The total number of atoms remains the same but the combinations are different. . Ionic compounds can form from transition metals. Transition metals do not always follow the patterns that we discussed. Can have more than one oxidation number (charge. ). To identify the charges of transition metals, roman numerals are placed in their name, directly after the transition metal. THINK ABOUT IT . Living things are made up of chemical compounds, but chemistry isn’t just what life is made . of—chemistry is also what life does. . . Everything that happens in an organism. —its growth, its interaction with the environment, its reproduction, and even its movement. Charniauskaya. 2016-2017. Plan for the Unit. Writing . chemical . equations. Reactants vs. products, writing equations from word problems, . diatomics. , states of reactants/products (s, l, g, . aq. Chapter Objectives. Describe the chemical processes used in biomass production and conversion to biofuels.. Explain balancing a chemical reaction as an application of the . law of conservation of mass. CONTENTS.
