9.1 Sulphuric Acid Sulphuric Acid is Manufactured in Industry 1. Sulphuric acid‚ H2SO4 is manufactured in industry through Contact Process. 2. The raw materials used are sulphur‚ air and water 3. The Contact process consists of three stages. Stage 1: The production of sulphur dioxide This can be obtained by two methods: 1. Burning of sulphur in dry air in the furnace S + O SO2 2. Burning of metal sulphide such as zinc sulphide or iron(III) sulphide in dry air. 2ZnS

Antacid tablets are used to relieve heartburn and neutralise stomach acid. Planning Aim To determine how the surface area of the tablets affects the rate of the reaction. To determine which form of tablets gives the biggest surface area resulting in the fastest reaction rate. Investigation question: What is the relationship between the total surface area of the tablets and the rate of the reaction? Hypothesis: The rate of reaction will be the fastest when the tablets crushed into powder as there

percentage errors. OBJECTIVE The objective of this experiment is to determine the order with respect to permanganate ion and to oxalic acid concentration for the reaction of potassium permanganate and oxalic acid solutions. Other goals include‚ writing a rate equation and determining the effect of increased temperature on the rate of this reaction. MATERIALS AND EQUIPMENT The materials required for this experiment include the following: • 2-50ml Burets • 60 mL of 0.755M H2C2O4 • 60

Erin Bolton Chemistry Lab Report April 29‚ 2015 Lab: Reaction Rates Introduction: In this experiment we studied the reaction of potassium persulfate‚ K2S2O8‚ with potassium iodide‚ KI. All chemical reactions have an energy barrier to overcome before the reaction will proceed. We will record data based on the concentration‚ temperature and catalyst for each experiment. Once this has been completed it will be graphed. Procedure: Due to the chemicals being used having hazard gloves are used

Once Upon a Time by Gabriel OkaraOnce upon a time‚ son‚they used to laugh with their heartsand laugh with their eyes:but now they only laugh with their teeth‚while their ice-block-cold eyessearch behind my shadow.There was a time indeedthey used to shake hands with their hearts:but that’s gone‚ son.Now they shake hands without heartswhile their left hands searchmy empty pockets.‘Feel at home!’ ‘Come again’:they say‚ and when I comeagain and feelat home‚ once‚ twice‚there will be no thrice-for then

Purpose: The purpose of the ‘Rates of Reactions’ lab is to learn how to plan an investigative lab without outside help and to learn about the ‘Rates of Reactions’. This lab will require students to take responsibility for their own learning and use their prior knowledge to aid in the completion of this lab. In the lab prepared below‚ students will be learning about Rates of Reaction with varying concentrations of Alka-Seltzer with water. Hypothesis: I believe that the more water added to the canister

of Marble chips and Hydrochloric acid Aim: We will measure the loss in mass of the marble chips (CaCO 3 ) as it reacts with Hydrochloric acid (HCl). This one method of measuring the rate of reaction. We will use a balance to measure this mass loss as the reactants are used up to form product. Safety: * As Hydrochloric acid is corrosive wear a lab coat‚ gloves and safety goggles. * Take care when using the glassware not to cut yourself. * When the reaction is taking place Carbon

PurposeIn this experiment‚ sodium hypochlorite (NaOCl) in acetic acid mixture was used to oxidize emdo-borneol (an alcohol) to camphor (a ketone). The product would then be purified by sublimation and then be analyzed by Infrared spectroscopy and melting point test. Procedure and ObservationsPlease refer to the lab manual and the carbon copy attached. Data and CalculationsWeight of endo-borneol = 0.2013gNo of moles of endo-borneol = 0.2013g/154.25g mol-1 = 1. 305mmolSince one mole of endo-borneol
