of Gases PURPOSE This experiment has two parts. The purpose of part A of the experiment is to determine the atomic mass of a metallic element whereas the purpose of part B of the experiment is to determine the rate of diffusion of both gases hydrogen chloride and ammonia by measuring the distances travelled by the two gases in the same time period. For part A the reaction of the metal with the aqueous acid is as follows: M(s) + n H3O+ -----> M+n(aq) + n/2 H2(g) + n H2O

purpose? Cannizzaro reaction is a reaction that uses a strong base‚ such as sodium hydroxide‚ which results to the formation of a carboxylic acid (or its corresponding salt) and an alcohol. It is only observed in aldehydes that do not contain alpha hydrogen atoms. Aldol condensation is a reaction in which an enolate ion reacts with a carbonyl compound to form an α-hydroxyaldehyde or β-hydroxyketone‚ followed by a dehydration to give a conjugated enone. c) Provide the type equations used in the test

Haloalkanes and Haloarenes Haloarenes Halogenated compounds persist in the environment due to their resistance to breakdown by soil bacteria. 10 Unit The replacement of hydrogen atom(s) in a hydrocarbon‚ aliphatic or aromatic‚ by halogen atom(s) results in the formation of alkyl halide (haloalkane) and aryl halide (haloarene)‚ respectively. Haloalkanes contain halogen atom(s) attached to the sp3 hybridised carbon atom of

Experiment #3 Mark A. Bruder 07. T.A. Michael Hall Alkanes: Chlorination Introduction: The purpose of this experiment is to determine the reactivity of hydrogen atoms on a carbon chain using free radical chlorination. In this experiment 1-chlorobutane will be chlorinated with the combination of sulfuryl chloride and ABCN as an initiator to produce the chlorine radicals. The combination of 1-chlorobutane and sulfur chloride will produce four dichlorobutane

1.0 Abstract This paper is done to study one particular catalyst which is zeolite supported iron catalyst. Zeolite supported iron catalyst is prepared using a method where it is based on the reaction of a metal exchanged zeolite with a metal containing coordination compound which produces an insoluble compound distributed throughout the zeolite. The metal used will be a specifically a water soluble metal cyanide complex where in this case it is iron. The catalyst is being used in various industries

Methods To determine the principals of osmoregulation‚ we sampled two lobsters from each tank and there were three different tanks which the water ranged in salinity. The experiment is to determine whether the six lobsters tested are osmoregulators or osmoconformers‚ this is done by obtaining a sample of hemolymph. The first step of the lab is to prepare the needle and syringe that will be taking the hemolymph. The syringe size was 1 ml‚ and the intention is to collect between 0.5 and 1.0 ml

This will be done by reacting the zinc with hydrochloric acid to form zinc ions in a single replacement reaction. The acid reacts with the zinc but not copper. The reaction of zinc metal with the hydrochloric acid (HCl) produces zinc chloride and hydrogen gas.

make them bond with each other easily. Thus organic compounds are classified according to their carbon chains that vary in length and shape. Hydrogen‚ nitrogen‚ and oxygen are the most common atoms that are generally attached to the carbon atoms. Organic compounds can be classified as hydrocarbons and hydrocarbon derivatives on the basis of their hydrogen replacements by other elements or by other group of elements (functional group).All hydrocarbons are insoluble in water because of their relatively
