Quick Review Atoms Elements Molecules Compounds What is a Chemical Reaction For a chemical reaction to take place we have to have two things Reactants Products Chemical Reactions cont This forms a chemical equation similar to equations you see in your math class. DEFINITIONS AND TYPES. Revision:. DO NOT WRITE- FOR YOUR INFO ONLY. We have looked at the period table, what atoms are, elements and compounds. You have learnt that atoms can join to make compounds or molecules and that we can mix compounds to make new compounds…..these are chemical reactions. It’s Logical. What is Logic?. Logic. – The science of correct reasoning.. Reasoning. . – The drawing of inferences or conclusions from known or assumed facts. .. There are two main types of reasoning:. Physical Science Notes. Physical Properties. PHYSICAL PROPERTY . - A feature or characteristic of matter which can be observed without changing the identity of the matter . Examples. :. . . Color. 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. Part . 1: Decomposition and Synthesis Reactions. . Objectives. -To identify decomposition and synthesis chemical reactions. -To predict the products of these two types of reactions. 2. Symbols in . Objective:. . Freezing/Melting;. . I will be able to . explain on the molecular level why a low enough temperature can cause the water vapor in air to condense to liquid water and then freeze to form ice. Because . entropy is a state function, . the property is what it is regardless of pathway, the . entropy change for a given reaction can be calculated by taking the difference between the . standard entropy. Add the new notes to your . table of contents. , and then turn to the next clean page and set up your title and date. Tape the two slides into your INB flat down, directly under your title - they do not need to flip up. 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. . 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.@.

Bowling Green Junior High. What are chemical reactions?. Chemical Reaction. . – . a change that takes place when two or more substances (reactants) interact to form new substances (products) with new properties..
