This paper is a full determination for certain chemicals and their boiling points. It lists some already but given the atomic numbers of any material this project includes a conversion and calculation chart to find the freezing point of most any material. GOOD LUCK! Abstract: In this lab we determined the freezing point‚ and Kf‚ of pure 2‚4‚dichloralbenzne as well as a 2‚4‚dichloralbenzne/biphenyl solution. We used this information to determine the molar mass of an unknown (#24) by the 3rd step

In the case of gram-positive bacteria‚ the cell wall is comprised of 60-90% peptidoglycan and is very thick. There are numerous layers of teichoic acid bound with peptidoglycan

------------------------------------------------- ABSTRACT ------------------------------------------------- The copper reaction experiment was demonstrated by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagents were being added. It was also demonstrated to practice the common laboratory techniques such as methods

The traditional TOK diagram indicates four ways of knowing. Propose the inclusion of a fifth way of knowing selected from intuition‚ memory or imagination‚ and explore the knowledge issues it may raise in two areas of knowledge. The study of Theory of Knowledge (TOK) indicates four distinct ways of knowing: sense perception‚ emotion‚ reason and language; however‚ in this essay I will argue

Chemistry II lab Why do liquids evaporate at different rates? Section1: Have you ever left a container with some type of liquid in it and wondered how it could it evaporate so quickly? The evaporation of an unpredictable liquid is an endothermic process that results in a temperature decrease. The amount of temperature decrease is related to the strength of intermolecular forces of attraction. The rate of evaporation can be described as the change of temperature divided by the time it takes to

Experiment #8 – properties of Alcohols and Phenols Introduction As has been mentioned before‚ over 20 million organic compounds have been identified. If each substance had to be studied as an entity completely separate from all the other substances‚ the study of organic chemistry as a whole would be impossible; that is to say‚ even more impossible than you currently believe it to be. Fortunately‚ the subject can be organized and it is often organized around the concept of the functional group
