In the chapter “Chemical reactions” from the book Saying yes in defense of drug use. It compares Muslim and Mormon Religion restrictions of substances that are acceptable for use outside of these religions. The chapter focuses on alcohol and caffeine‚ but there are other substances that are mentioned as forbidden. Alcohol and caffeine highly addictive yet they are widely available for purchase in stores however the substances are viewed as illicit substances. In the Muslim tradition‚any intoxicant

group of four reactions‚ Iron phosphate and calcium phosphate are the two products that are insoluble in water. In the three of the four reactions a cloudy white or yellow formed. This indicated the formation of a precipitate‚ caused by the generally insoluble phosphate anion. Potassium chloride‚ Iron nitrate‚ and potassium sulfate where the products which were soluble in water. With these products there was no evidence of a precipitate forming. 2. Based on the results from reactions A and B for

The progress of the reaction was monitored in my case using two TLC plate. It first started off with the spotting of Standard benzoin and benzil which were provided in the lab and followed by the addition of the reaction mixture at once it starts changing colour/boiling‚ then at 10 and 20 mins into the reflux. Once all the necessary steps were spotted‚ the TLC plate was placed in in a beaker containing CH₂Cl₂(methylene chloride)‚ which was used as the developing solvent in this experiment. To check

Purpose: The purpose of this experiment is to: determine the limiting reactant of a chemical reaction that involves iron filings and a copper sulfate solution. Second‚ to determine the mole ratios between iron and copper and to show that a single replacement reaction occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method used

Single Displacement Reaction The objective of this experiment was to observe evidence of a reaction and to determine the chemical equation‚ if there is a reaction. In order for a reaction to occur‚ a metal strip must have evidence of black or grey deposits on the surface of the metal once dipped into the solution. The reactivity of an element is related to its tendency to lose or gain electrons. Three metal strips that were used are copper‚ lead and zinc as well as the solutions of silver nitrate

2.MATERIALS and METHODS 2.1. Nature of Reactants 2.1.1 We placed 3mL of 3 M HCl into each of 3 seperate test tubes. Next we added mossy zinc to the first test tubes‚ Sn granules to the second and Cu filings to the third and compared the rates of evolution of hydrogen gas in each test tube. 2.1.2. We mixed 3mL of 0.02 M KMnO4 and 2mL of 3 M H2SO4 in a test tube and stirred using a glass rod. Next‚ we divided the solution into two. We added 2mL of 0.03 M Na2C2O4 solution to the first half and

The color change proved it was a chemical change. #2 The reaction turned yellow and it separated and created a fog. The solid formed precipitation and had a color change during the reaction proving it to be a chemical change. #3 There was green smoke and the crystals turned black. The green liquid turned dark green and continued to sizzle with

Study of Chemical Changes: Types of Chemical Reaction INTRODUCTION Chemical changes are results of chemical reactions. All chemical reactions involve a change in substance and a change in energy. They are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. There are different types of chemical reaction classified into 4 general types‚ namely‚ Synthesis‚ Decomposition‚ Single Replacement

THE CLASSIFICATION OF CHEMICAL REACTIONS Danny Bhatt SCH3U0-G Mr. Gandhi Wednesday‚ April 1st‚ 2014 INTRODUCTION The purpose of this lab is to determine the different types of chemical reactions and differentiate between them based on similar characteristics of each set category. In this lab it is hypothesized that every chemical reaction which was observed would fall under already set categories (that are: synthesis‚ decomposition‚ single displacement‚ double displacement‚ combustion and

Chapter 13‚ “Chemical Reactions”‚ was also of great interest to me. “A change that alters the chemical composition of a substance and hence forms one or more new substances is called a chemical change‚ or more often‚ a chemical reaction (James T. Shipman 342).” In this summary paper‚ I will discuss some of the highlights of the chapter. An awesome example of a chemical reaction is that of photosynthesis‚ found in green plants. In photosynthesis‚ plants absorb carbon dioxide gas from the air
