Mixture Melting Points Abstraction Determining the melting point is very significant in order to identify an unknown. In this experiment‚ measuring the melting point was done by using melting point apparatus. The melting point of the unknown sample #10 was 111.5˚C. There were two possible compounds which were dibenzoyl ethylene and o-Toluic acid because their melting points were 111.2˚C and 109.8˚C when each compound was mixed with the unknown. Therefore‚ the unknown #10 was dibenzoyl ethylene

The Importance of Point of View “Robert and the Dog” Point of view in a story is something I find extremely interesting‚ simply because of the obvious fact that every single one of us have our own way of seeing things. Every one of us has a different point of view. For instance‚ when it is raining outside‚ my first thought would probably express some sort of happiness. The majority of people in Norway‚ would‚ on the other hand‚ probably complain. It’s all about perception. Analyzing literature

BOILING POINTS AND MELTING POINTS PART 2 Name: Grethel Zegarra Date of Lab: October 26‚ 2010 Date lab is due: November 2‚ 2010 HYPOTHESIS The boiling point in degrees Celsius will increase as the number of carbon atoms increase. The melting point of the unknown will indicate its mixed substances. The boiling point will increase as a result of the different branching of the OH‚ the melting point will be affected by the different positioning of the OH on the benzene ring. PURPOSE To introduce

Introduction The melting point is defined as the temperature at which the solid is in equilibrium with its liquid‚ and this characteristic is very unique‚ so a substance can be determined by the melting point. Determination of the melting point is very important technique in many areas of chemistry especially‚ in organic chemistry area because the melting point is really significant in order to identify the purity and the identity of a substance. Measuring the melting point is a fast and cost-effective

there are two kinds of points of view: the first-person point of view‚ and the third-person point of view. In the first-person point of view a fictitious observer tells us what he or she saw‚ heard‚ concluded‚ and thought and is usually characterized by the use of the pronoun “I”. The speaker or narrator may sometimes seem to be the author speaking directly using an authorial voice. For example‚ Nick Carraway in “The Great Gatsby” tells the story in a first-person point of view‚ sharing with the

the high waves that are menacing their existence (paragraph 9). At about paragraph 49‚ however‚ the speaker shifts his concentration primarily to the correspondent‚ while he describes the other men more dramatically. Might we assume that at this point‚ Crane is merging the speaker of the story with his own voice‚ as nearly as we can determine it? Throughout‚ the speaker introduces some of his own ideas‚ and also‚ at times‚ speaks ironically. This accounts for some of the more humorous expressions
