With your phone take a . close-up picture of BOTH sides of a coin. Examine the picture CLOSELY and determine how . many TOTAL atoms . of silver make up Mr. Lawson’s net worth!. Displacement Reactions. Lets look at the reaction between chlorine and potassium bromide. When chlorine is bubbled through potassium bromide solution (colourless), the liquid turns red-brown, because bromine forms.. and. ATOM . ECONOMY. Reactants . (raw materials). Products. Most of the substances we use every day are made from RAW MATERIALS, often through complex chemical reactions.. . Chemical reactions. Pottington. Yes…it’s still stoichiometry…. Think about making grilled cheese…. To make a . decent . grilled cheese sandwich, you need two pieces of bread, 2 pieces of cheese, and 1 pat of butter. Write an equation that describes making a grilled cheese sandwich. . Aka REDOX reactions. Electrochemistry. The study of chemical reactions involving the transfer of electrons between reactants. . Oxidation. Loss of electrons. happens at the anode. Reduction. gain of electrons. What is a limiting . r. eagent?. Steps for . determining the limiting reagent . Percent Yield. TeachWithFergy . Preview File. Please enjoy this preview of your Student Version of the lesson. . Some slides appear blank because they have been removed.. Percent Yield. What is percent yield?. Theoretical Yield. – the maximum amount of product that can be produced from a given amount of reactant. This is determined . mathematically. using stoichiometry calculations. Can you spot three (3) differences?. Can you spot the differences in the reactions?. (1) 2Mg. (s. ) . O. 2(g) . → . 2MgO. (s. ) . (2). CaCO. 3(s) . →. . CaO. (s) . CO. 2(g). (3) . NaOH. (. All . sodium, potassium and ammonium . compounds are . soluble.. All . nitrates. are . soluble. All common . ethanoates. (also called acetates) are . soluble. Most common . chlorides . are . soluble. 9-3. 9-3 Learning Targets. Identify the limiting reactant in a chemical equation. Identify the excess reactant and calculate the amount remaining after the reaction is complete. Calculate the mass of a product when the amount of more than one reactant is given. 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.. 1. Metal . carbonates such as calcium carbonate break down when heated strongly. This is called . thermal decomposition. . Here are the equations for the thermal decomposition of calcium carbonate. :. III.. . Limiting Reactants. . A. Why do reactions stop? Are all reactions 100% efficient?. Reactions might . stop. for a number of reasons including: . consumption. of one or multiple reactants; occurrence of side reactions; . DO NOW – . Using last lessons knowledge fill in the blanks. Potassium + Hydrochloric acid .  Potassium Chloride + Hydrogen. Lithium + Water  Lithium Hydroxide + Hydrogen. Copper + Oxygen  Copper Oxide .
