PPT-Ch 4: Types of Chemical Reactions and Solutions

Stoichiometry Do Now True or false Most ionic substances need an aqueous medium in order to react Reactions occur at the level of atoms and molecules therefore count of each reactant atomsmoleculesions needs to be known in order to determine how much product can be produced . 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. 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. Synthesis reactions. Decomposition reactions. Single replacement reactions. Double replacement reactions. (Precipitate reaction). Chemical Reactions can be written as:. Word equation. Chemical equation. 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. 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. CONTENTS. CHEMICAL REACTION. CHARACTERISTICS OF 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. The key words are emphasized in bold . and there is a list of them at the end of the presentation. . Chemical Reactions. When a chemical reaction occurs, new substances (called . products. ) form from the substances taking part in the reaction (called . Objectives. Compare chemical reactions to physical changes. Compare parts of an atom. Calculate the mass of one mole of an element or compound. Explain how ionic and covalent bonds are formed. Identify the parts of chemical equations. What is a Chemical Reaction?. A Chemical reaction occurs when ever a chemical bond is formed, broken or rearranged.. A chemical reaction will always create a new substance..
