If a chemical reaction occurred‚ write a balanced equation for it. Then using the A‚ B symbols‚ write a general equation for a single-displacement reaction. Here are the chemical formulas of the reactants for each reaction: • zinc – Zn copper sulfate – CuSO4 • aluminum – Al copper

There are many types of chemical reactions‚ five general ones of which I will be describing. Chemical changes are a result of chemical reactions. All chemical reactions involve a change in substances and a change in energy. Neither matter nor energy is created or destroyed in a chemical reaction‚ only changed. There are so many chemical reactions that it is helpful to classify them into 5 general types‚ which include the following: synthesis‚ combustion‚ decomposition‚ single-replacement‚ and double-replacement

Determination of Rate and Order of a Reaction Results This experiment used a spectrometer to find the wavelength with maximum absorbance in a green food coloring solution. For this particular solution the wavelength was 629.7 nm. The system was then calibrated to that and was set to measure the food coloring and bleach solution. The measured visible light absorbance of the mixed solution was collected over a time of 200 seconds and eight points were then selected and placed into the Absorbance

Introduction The purpose of this lab is to be able to observe the reaction rates of different chemical substances‚ by looking at which substance is the fastest reactant. This is what chemical kinetics is. Reaction rate is the change in the concentration of a reactant or product in a chemical reaction per unit time. In this lab the requirement was to be able to calculate each Average reaction rate which is the change in reactant or product concentration at a given time interval. Some equations that

Replacement Reactions (Data and Calculations) Objective: Classify the chemical reaction through observation‚ which each reagent produce when mixed with another reagent. After careful observation‚ be able to prove each observation using the net ionic equation. Background: First‚ a double-replacement reaction is when two cations in different compound switch anions‚ AX + BZ → BY. If either compounds are insoluble a precipitate occurs‚ and if there is no precipitate formed there is no reaction. Also‚

Megan Wierzbowski Organic II Laboratory Wed. 11-1:50 Title: Grignard Reaction with a Ketone: Triphenylmethanol Part 1 Objective: The goal of this experiment is to learn to make Grignard reagents. The reactions of the Grignard reagents with ketones form tertiary alcohols. These reagents are highly air- and moisture-sensitive materials. We will observe the formation of the Grignard reagents‚ which magnesium metal is transformed into organometallic salts. Experimental Procedure:

Title: Effect of a Catalyst on Reaction Rate II. Introduction: The basis of the experiment is the enzyme; an enzyme is a biological molecule that acts as a highly selective catalyst. By combining with a substrate‚ an enzyme is able to create a new product that helps the body function. (Ex. Lactose/Lactase) A substrate is a molecule an enzyme acts upon‚ the two combine at an area called an active site. This active site allows induced fit which allows the reaction to occur and a new product to be
