CHAPTER I OVERVIEW OF THE PRODUCT STUDY A. OVERVIEW OF THE PRODUCT Combitido is primarily engaged in the business of selling affordable Embutido with vegetables on it. Our Embutido‚ offered different kinds of combinations: Chicken‚ Pork‚ Beef‚ Fish. For more testing‚ we situate it with potatoes‚ carrots and monggo. B. LOGO “Combi” means combination and “Tido” comes from the word Embutido. We use an animated picture to show liveliness of the company. The 4 animals which is

to extract and crystallize compounds in a mixture using acids and bases. 1 gram of the unknown was dissolved into 30 mL of ethyl acetate. The mixture was then transferred to a separatory funnel. Using aqueous solutions of different pH we were able to separate organic acids‚ bases and neutral compounds from each other. Using three 10 mL portions of HCl‚ we reacted the HCl with the base in solution. This made it possible to extract the base from the mixture. Organic acids are highly soluble in aqueous

called a CHROMATOGRAPHY. This simple experiment illustrates all of the essential steps of a process which is in constant use in laboratories to effect separate mixtures of compounds‚ both organic and inorganic. It should be not inferred from the experiment that just mixtures with color can be separated; also the uncolored mixtures can be separated by this technique‚ but as might be expected‚ the details of the operation need to be modified‚ depending on nature of the substances being handled

Discussion: Continuous distillation‚ a form of distillation‚ is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams. A distillation is the separation or partial separation of a liquid feed mixture into components or fractions by selective boiling (or evaporation) and condensation. A distillation produces at least two output fractions. These fractions include at least one volatile

SUMMARY FOR GRADE 7 FIRST SEMESTER Importance of Chemistry Chemistry is an important branch of science. Chemistry deals with the matter that form our environment and the transformation that the matter undergoes. Chemistry is therefore‚ useful in understanding the changes taking place in the constituents of the environment and the resulting advantages. Chemistry is connected with composition‚ structure and properties of the matter. In fact it is a science of atoms and molecules. Organic chemistry

from a mixture (50:50) of hexane and toluene. Hexane was separated from toluene and was observed from the gas chromatography‚ it showed that hexane increased from 0.0.873 to 0.886 moles. Once the mixture of toluene and hexane hit 70 degrees in the experiment‚ the distillate was used for the gas chromatography. Hexane was higher in the distillate stage. The first drop of condensation appeared at 79°C. The volume of the distillate was 0.88ml and 0.98ml for the residue volume. The initial mixture had

This reaction is characterized by the combining of an alcohol and an acid (with an acid catalyst) to yield and ester plus water. In order to accomplish this reaction‚ the reactants were refluxed for 30 minutes at 80 degrees Celsius ‚to yield a mixture‚ the mixture was then mixed with sodium hydrogen carbonate and dried with anhydrous sodium sulfate. The product obtained from this reaction was then weighed and yielded 3.5753g‚ the total percent yield of isopentyl acetate obtained was 60 %. The advantages

Estimation of the Activation Energy for the Iodination of Acetone Through the Effect of Temperature on the Rate Constant Joel Costa‚ Alex Fuentes‚ Michael Chea‚ Rex Nwerem Dr. Morgan Ferguson July 9‚ 2013 ABSTRACT | It is often important to determine the rate at which a chemical reaction takes place‚ i.e.‚ how fast it yields the desired products. Temperature is one of the factors that influence the rate of reactions and it does so by providing energy to reactant particles so that a larger

electrons. Molecules can be multiple atoms of the same element combined or the elements can be different. When the atoms are combined they become a compound and are given a new name which can sometimes relate to the original atoms used to create it. A mixture is the term given to two or more compounds combined.
