PPT-Sample Exercise 3.1 Interpreting and Balancing Chemical Equations

Solution a The left box which represents the reactants contains two kinds of molecules those composed of two oxygen atoms O 2 and those composed of one nitrogen atom and one oxygen atom NO The right box which represents the products contains only molecules composed of one nitrogen atom and two oxygen atoms NO.

Load Sharing. 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.. EQ: How are changes in matter related to changes . in energy?. Changes in Matter. You are at the beach. You built a sandcastle!. You notice storm clouds gathering in the distance.. You are sad : (. You know your sandcastle is about to go bye-bye.. 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). Can’t Create or Lose Atoms. A.

Balancing equations and reacting masses. Objective:. To know how to balance equations and how they can be used to calculate masses of reactants needed and products made. Outcomes:. Write full balanced symbol equations. Aran Bergman. (Technion, VMware). Naga Katta, Aditi . Ghag. , . Mukesh. Hira, . Changhoon. Kim, Isaac . Keslassy. , Jennifer Rexford. CLOVE. 1.

The Law of Constant Composition. However you make a compound, it always contains the same elements in the same proportions by mass.. This tutoring session is designed to help anyone who is struggling balancing equations. Remember!. Matter can never be created nor can it be destroyed (Theory of conservation of matter). This means that whatever elements go into a chemical equation (Reactants) must also come out of the chemical equation (Products). 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. Sig Freund. Outline. Introduction.
