1) Demonstrate understanding of the terms atom and molecule. Atom= Smallest Unit of Matter Molecule= 2 or more atoms chemically bonded. 2) Describe paper chromatography. 3) Interpret simple chromatograms. A method used to separate a Solution‚ using a Paper and a beaker of water. The Substances in the Paper go up depending on their Mass. We can say that a Solution has the same substance as another solution because they form a line of the same height. 4) Describe methods of separation

The eerie lifeless doll‚ stripped of its features with each dramatic cut made by a creature composed of needles‚ as well the dark composition and sharp ominous score‚ made the opening scene of Coraline highly recognizable in the film industry and introduced the audience to a gothic animated world like no other. Coraline‚ released in 2009‚ focuses on an eleven year old girl and her journey through an alternate dimension that leaves her appreciating her own reality. The film is based on the book by

More than anything else‚ imaginative journeys are about the process of speculation. Do you agree? Argue your point of view. Imaginative journeys take us from the reality now and transfer us into unreal existences or different worlds that not only entertain us‚ but help us to learn more about the world we inhabit and ourselves. This journey requires the process of speculation and contemplation. In texts‚ the imaginative journey involves speculation from the composer as well as the responder

experiment is to establish the stoichiometry of the reaction between titrate oxalate (C2O42-) and permanganate (MnO4-). The purpose of the second part of today’s experiment is to learn about the concepts of the rate of chemical reactions and homogenous catalysis. Broad Overview of the Experimental Method: The purpose of the first part of today’s experiment will be accomplished by performing titrations. A solution with C2O4- of known concentration will be titrated with MnO4-. The second purpose will be

One evening in 1950 a Houston couple entered a Chinese restaurant. The woman‚ a radio writer‚ wanted the proprietor’s help in producing a program on recent Chinese history. Overhearing their conversation‚ a nearby man rushed out‚ phoned the police‚ and informed them that people were "talking Communism." The couple was immediately arrested and jailed for 14 hours before the police concluded they had no case. At about the same time a policeman in Wheeling‚ West Virginia‚ discovered some penny-candy

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the

Aims The aims of this investigation are: 1. To find the rate equation of the reaction of hydrogen peroxide and iodide ions. This will be achieved by using an iodine clock method and colorimetric analysis. 2. Draw a graph of rate against concentration for each reactant (Hydrogen peroxide‚ potassium iodide and H+ ions). 3. Finding the order for each reactant 4. Finding the rate-determining step. 5. Proposing a mechanism for the reaction. 6. Using Arrhenius’ equation to find the activation

FEMINITY IN CONTEMPORARY HORROR FILM One might say that horror film- genre has been invented by feminists. Horror films seem to be one of the only genres that have women as heroines instead of dominated side characters. In horror genre women are the ones fighting against evil and men are the ones dying trying to help these heroines. Or perhaps the horror genre uses heroines to differ it self from hero dominant action genre. Or maybe horror films were created to represent the ultimate horror of

SYNTHETIC EXPLOITATION OF ENZYMES: BIOCATALYSIS IN ORGANIC SOLVENTS: FUNDAMENTALS ENZYMES IN ORGANIC SYNTHESIS 1. Enzymes catalyze a broad spectrum of reactions with high turnover numbers. Rate enhancements approach 1012 fold. 2. Enzymes may accept a wide range of substrates. 3. Enzymes are highly regio and stereoselective. 4. Enzyme reactions take place under mild conditions; this minimizes problems of isomerization and racemization. 5. Enzymatic processes are less hazardous and polluting
