Observations of Chemical Changes Purpose: The purpose of this experiment is to predict and examine chemical changes/reactions among common chemicals found in consumer products at a macroscopic level. Procedure: The procedure of this experiment was to carefully mix different chemicals together using the chemical filled pipettes and the 96-well plate and determining what chemical reactions occurred.

Determining the value of molar mass of chosen compound Marta Dürrigl 1mmA Chemical reaction: b.) CaCO3 (s) + 2HCl (aq) ----------- CaCl2 (aq) + CO2 (g) + H2O(l) AIM: The aim of this investigation is to experimentally determine the molar mass of carbon dioxide (CO2) by measuring its volume and calculating its mass. CO2 which we will measure will arise as a product of a chemical reaction between Calcium Carbonate (CaCO3) and Hydrochloric acid (HCl) as it is shown in the chemical

Experiment 1: Mechanism of Nitrile Oxide and Alkene Cycloaddition 1. Purpose: to clarify the mechanism for the cycloaddition reaction between benzonitrile oxide and an alkene‚ and to test the regiochemistry of the reaction between benzonitrile oxide and styrene. 2. Plan: Each student in a group of three will work to create a reaction with the Benzonitrile Oxide with‚ cis-stilbene‚ trans-stilbene‚ or styrene in an Erlenmyer flask. With this Reaction solution thin layer chromatography will be

Q_1 From the Exhibit 4‚ U.S. Frasch Sulphur Industry Prices and Profitability‚ 1940-1967‚ we can get the information about the variations in the return on invested capital earned by the industry over the several decades. In sulphur industry‚ the return on invested capital was around 15% from 1940 to 1945. From 1946‚ rate of return began to increase dramatically‚ starting from 16.2 %( 1945)‚ and reached 33.8% in 1950. This high rate of return kept for couples of years (1951-1955)‚ ranging from 29%
