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. Chemical change. . Reactions with acid. . Reactions with oxygen . 7F. 7F Simple chemical reactions. Chemical change. . 7F Simple chemical reactions. 7F Chemical change – Changing materials. How many different materials can you see in this bedroom?. 1 – Nature of Chemical Reactions. 2 – Chemical Equations. 3 - Reaction Types. 4 – Reaction Rates and Equilibrium. State Standards. CLE.3203.1.9 – Apply the Laws of Conservation of Mass/Energy to balance chemical equations. 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). Synthesis reactions. Decomposition reactions. Single replacement reactions. Double replacement reactions. (Precipitate reaction). Chemical Reactions can be written as:. Word equation. Chemical equation. Chemical Reactions. :. A . chemical reaction . is a process that changes one set of chemicals into another by rearranging chemical bonds. The elements you start with are . reactants. The elements you end with are . Chemical Reactions. A . chemical reaction . is a process that changes, or transforms, one set of chemicals into another by changing the chemical bonds that join atoms in compounds. . @Mass and energy are conserved during chemical transformations.@. Chemical reactions. A . chemical reaction . is when one or more substances change into different substances. . Example . iron + sulfur .  iron (ii) sulfide + energy. Go to textbook Page 225. Read page 225 and write definitions for the following into your notes.. Changes or transforms chemicals into . other. chemicals. Ex: Iron + Oxygen . . Iron Oxide (rust). Physical Science Review. What is the product?. What are the reactants?. Chemical formula. . shows the kind and proportion of atoms of each element that occurs in a particular compound. Net ionic equations are useful in that they show only those chemical species directly . participating in . a chemical . reaction. The keys to being . able to . write net ionic equations are the ability to recognize monatomic and polyatomic ions, . Chemistry 1-2. Mr. . Chumbley. Section 1: Describing Chemical Reactions. Chemical Reactions. A . chemical reaction . is a process by which one or more substances change to produce one or more different substances. 4.2: Classifying chemical reactions. Define three common chemical reaction types: . (1) precipitation; (2) neutralization; (3) redox. Classify reactions given a balanced chemical equation. Identify common acids & bases. All. chemical reactions either release or absorb energy. . The energy can take many forms: . HEAT. , . LIGHT. , . SOUND. , and . ELECTRICITY. . Chemical . bonds. are the source of this energy. . Write your answer in your. . science journal.. Quiz. 1. How . many molecules of oxygen gas in the reactant (O. 2. ) are needed to balance this equation?. CH. 4. + O. 2. → 2CO. 2. + 4H. 2. O.
