the reaction of butanols with hydrobromic acid. Before the lab began we discussed and proposed mechanisms. (see “Mechanisms”) To begin this experiment we calculated how much of each material we were going to be using‚ and the numbers we chose to use differed from our reference text slightly. We used 6.5 mL of our assigned butanol and only 4 mL of sulfuric acid. Going back to our reaction mechanisms‚ we were looking at SN1 and SN2 reactions‚ so we of course used the hydrobromic acid as our acid catalyst

Cowley Paper #1 During the sixteenth‚ seventeenth‚ and eighteenth century the primary driving force for all cultures can be summed up by one simple word‚ and that word is greed. Many of the countries that had power at the time were greedy savages and all they wanted was more land and power. Countries that were powerful at the time were Spain‚ Portugal‚ Japan‚ and others. Also in the countries the governing body of them had their way or the highway they did not care what had to be done or who

description on acid rain as well as a focus on acid rain in eastern Canada. This report contains a very helpful basic background on acid rain as well as a questionnaire. It involves an annual report on the Federal-Provincial Agreements‚ sulphur dioxide emissions in the seven most eastern provinces‚ trends in acid deposition in the Atlantic provinces from 1980-1994‚ as well as acid precipitation in Kejimkujik‚ Nova Scotia. It also includes data tables‚ graphs and interesting facts concerning acid rain.

Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will

Atausch July 28‚ 2014 Bio 102 Lab Final Exam: Acids and Enzymatic Reaction Purpose: To examine how an acidic fluid will modify the outcome of an enzymatic reaction. Introduction: Enzymes are “specialized proteins made by living cells that serve as biological catalysts.” (eScience Labs‚ LLC‚ 2013) These enzymes “allow certain industrial processes to be carried out at normal temperatures and pressures‚ thereby reducing the amount of energy and expensive equipment needed.”(BBC‚ 2012) Enzymatic

the effect of concentration on the rate of a reaction Research question: To what extent does the concentration of hydrochloric acid affect the rate of the following reaction: 2 HCl(aq) + CaCO3(s) → CaCl2(aq) + H2O(l) + CO2(g) Data Collection and Processing: Table1: Different volumes of Co2 gas produced by Different concentrations of HCL acid. Volume of CO2gas formed from 5 different concentrations of HCL acid ±0.5ml 5 different concentrations of HCL acid (Mol) ±0.5ml Time (sec) ±0.1 0.25mol 0.50mol

then I will see the temperature slope increase in the reaction with an increased concentration because with an increase of moles‚ the particles will be colliding more often‚ therefore increasing the probability that the proper energy and alignment will occur to create more collisions in the same amount of time. Methods: List of Materials: • 110 mL of NaOH at 1 M (10 mL per run) • 110 mL of NaOH at 0.5 M (10 mL per run) • 220 mL of Acetic Acid at 50% (10 mL per run). • Vernier Temperature Probe.
