State University Chemistry 302 7/31/12 Abstract This paper looks to delve into the chemistry behind ketones and aldehydes as well as related compounds. The endeavor involved looking into the way their bonding influences how they react. It also considers the simple physical properties of these compounds including their reaction with other compounds‚ chemical structures and formulas. The paper also looked to establish the relationship and differences between natural butter and synthetic butter

Balinese architecture has be divided into 6 parts which are the family compound‚ the pavilions‚ the temple courtyard and gates‚ the kul-kul and shrines‚ the palaces and also the water palaces (Wijaya & Granquist‚ 2005‚ p97) . Balinese residential architecture is based on ancient traditional Javanese style combined with Hindu religion and culture. The concept behind this architecture is the openness of space within its compound and also the Hindu religion. Researches have come a few conclusions about

extraction. Extraction is a systematic process of separating mixtures of compounds‚ taking advantage of the affinity differences of compounds to separate them (Padias 128-37). This technique recognizes the principle that “like dissolves in like‚” that is‚ polar solutes dissolve in polar solvents and non-polar solutes dissolve in non-polar solvents. Through extension of this principle‚ one can use extraction to separate compounds of a mixture. There are three different methods of extraction; solid-liquid

reactions occur when two elements or compounds combine to create one single compound. The general equation of synthesis reactions is: A+B→AB. The following are the complete balanced equations for the five synthesis reactions performed in the lab. Reaction 1: Reaction 2: Reaction 3: Reaction 4: Reaction 5: The reaction of CO2 and water is a prime example of a synthesis reaction. This is a synthesis reaction because it follows the general equation and the two compounds of H2O and CO2 combine to make

Thin Layer Chromatography (TLC) is a solid-liquid technique in which the two different phases are a solid stationary phase and a liquid mobile phase. TLC can be used to detect a given compound in a mixture‚ follow the course of the reaction‚ follow the purification of a compound‚ or evaluate the purity of the compound. Objectives: Certain objectives needed to be met in order for the Thin Layer Chromatography (TLC) experiment to be understood and completed. The identification of an unknown‚ and

the atomic masses of all the atoms present in one molecule of that compound. Example: the molecular mass of sodium bromide‚ NaBr‚ is 103‚ which represents the sum of the atomic mass of sodium (23) plus that of bromide (80). * Calculating the Molecular Mass (Formula Mass) of a Compound * To find the molecular mass of a compound‚ add the atomic masses of all the atoms that are present in that compound. * In the compound H2O‚ the molecular mass can be calculated by adding the mass of two

MATHEMATICS OF INVESTMENT Simple Interest If you borrow a car from a car rental company or if you live in someone else’s house or apartment‚ you have to pay rent. Like paying rent for the use of a car or a house‚ you also have to pay rent for the money you borrowed. This is called interest. People like Marco earn by charging interest on loans. Banks earn most of their income from the interest that people pay for the amounts they borrow. How much interest one has to pay depends on three factors:

insertion reactions involve the insertion of a carbene‚ a neutral carbon atom or molecule with two unpaired valence electrons‚ into an unactivated carbon-hydrogen bond. This reaction produces many commercially valuable compounds. The reaction itself involves the use of diazocarbonyl compounds which contain an N2 ligand on a carbon alpha to a carbonyl. The reaction is thermodynamically favourable as it involves the release of nitrogen gas. The carbon hydrogen bond is extremely strong and is difficult to
