PPT-Chemical reactions tutorial

Lets get started Goals In this tutorial you will learn How to recognize 3 of the 5 types of reactions Predict the products of reactions when only given the reactants What are the 5 types of reactions. 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. 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. Chemical Reactions. Investigation One. Chemical compounds are formed when two or more elements combine.. H. ₂ + O .  H₂O (water). Na + . Cl.  . NaCl. ( Sodium Chloride – Salt). Chemical Compounds. Chemical Equations. This equation means:. 4 Al(. s. ) + 3 O. 2. (. g. ) 2 Al. 2. O. 3. (. s. ). 4 Al atoms + 3 O. 2. molecules yield 2 molecules of Al. 2. O. 3. 4 Al . moles. Theme: . Changes and Reactions . LecturePLUS Timberlake. 2. color. melting point. boiling point. electrical conductivity. specific heat. density . state (solid, liquid, or gas). . 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 . 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. 10.1 . Reactions and . Equations. Evidence of Chemical Reactions. ..  . The process of which the atoms of one or more substances are rearranged to form different substances is called a . Chemical Reaction. Chemical Reactions. A chemical reaction . is the process by which one or more substances change into one or more new substances.. Reactants . are the original substances in a chemical reaction.. Products . 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. What is a chemical reaction?. A . chemical reaction. is a process that converts one or more substances into another substance.. Chemical Reactions. The starting substances are the . reactants. .. The resulting substances are the . 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. 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. 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.
