Homework 3 4. Discuss the benefits and drawbacks of a binary tree versus a bushier tree. The structure of binary is simple than a bushier tree. Each parent node only has two child. It save the storage space. Besides‚ binary tree may deeper than bushier tree. The result record of binary may not very refine. 5.

EXPERIMENTAL PROCEDURE: 1. 2.07 g of the mixture of naphthalene and benzoic acid was weighed accurately on a balance. The mixture was then dissolved in 40 ml dichloromethane and the solution was poured into a separatory funnel. 2. 20 ml of aqueous sodium bicarbonate solution was added to the dichloromethane. A stopper was placed on the separatory funnel and was shaken and pressure was frequently released. The 2 liquids separated into clear layers and the lower layer (dichloromethane layer) was

Alkenes from Alcohols: Analysis of a Mixture by Gas Chromatography Aim: To analyze a mixture of alkenes by gas chromatography. Introduction: In this lab‚ we specifically used elimination reaction; however we only used the E1 reaction. In the presence of strong acids‚ alcohols protonate to form a good leaving group‚ namely water. Upon loss of a proton to a good leaving group‚ an introduction of unsaturation (a double bond) can be preformed. According to Wikipedia‚ an E2 reaction is typically

water came from outer space to Earth. The water was brought to the planet for the comets. The water has a different structure for each state (gas‚ liquid‚ ice). Liquid water has random molecules. On the other hand‚ the ice has a more stable structure. The different structure between ice and liquid water can explain why the ice has less density than liquid water. Temperature is responsible for increasing the dissolution of components‚ and electrical conductivity. Pure water is not a good conductor‚

5.05 Mixtures and solutions Lab report Ink Chromatography Chromatography is also used to compare and describe chemical substances. The chromatographic sequence of sorbed substances is related to their atomic and molecular structures. A change in a chemical substance produced by a chemical or biological reaction often alters the solubility and migration rate. With this knowledge‚ alterations or changes can be detected in the substance. Chromatography serves mainly as a tool for the examination and
