Chemical Equation Chemical Reaction: C10H8+ 12 O2 → CO2 + 4H2 O (Naphthalene) Combustion Introduction of the Product: Naphthalene is an organic compound with formula C10H8. It is the simplest polycyclic aromatic hydrocarbon‚ and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. As an aromatic hydrocarbon‚ naphthalene’s structure consists of a fused pair of benzene rings. It is best known as the

Chemical Reactions & Equations CHEMICAL REACTION : In a reaction when the original state of the particle changes and it cannot be reversed by simple physical means‚ this type of reaction is known as chemical reaction. Example :- Fermentation of grapes‚ burning of wood etc. In this reaction we have seen that after burning of wood‚ coal is formed and we cannot make wood from coal. PHYSICAL REACTION : In a reaction when original state of the particle can be recovered by any means then this type of

A federal law was passed barring entry to all convicts and prostitutes. Before then‚ immigration was scarcely controlled. Over centuries different laws were passed in attempt to get the situation under control. Once the Immigration Law passed‚ legal immigration

Reaction Paper A company in a few short years becomes a well-known domestic enterprise. Since attracted international market‚ have not explored aware of the pros and cons of foreign markets‚ it has to enter the markets of other countries. I agree with the authors‚ it’s better to think more carefully and use of analytical tools to make accurate judgments and make the most important decision-making. The distance between the two countries can be revealed‚ along four basic dimensions: cultural distance

Each and every one of us has their own reaction about the third State of the Nation Address of President Benigno “NoyNoy” Aquino III. There’s always a negative and positive reaction. We always have comments in every part of the SONA especially the topics and issues that the president have mentioned‚ even the language that the president used. Most of the issues in our country were mentioned by PNoy like the billions wasted by PAGCOR for coffee. I agreed with what PNoy said‚ wondering if the people

on top of the shorter cup to prevent any heat loss to the air. Then the shorter cup was secured on a base with tape and a hole was drilled with a stir stick on the top of the taller cup to allow the stir stick and a thermometer reach the chemical reaction. With the calorimeter set up and ready‚ the experiment was ready to be conducted. The calorimeter was placed on a metric scale and tared. Then 2.5g of a substrate was measured out using a small scoop and placed in the calorimeter. A scale was used

precipitation reaction is‚ describe ways which one can predict whether a precipitation reaction would form or not‚ describe the uses of precipitation reactions in everyday activities and industries BACKGROUND INFORMATION: Precipitation is the formation of a solid in a solution during a chemical reaction‚ such as evaporation. A substance that causes precipitation when it is added to a solution is called a precipitant. This can occur when an insoluble substance is formed in the solution due to a reaction or

Experiment 3: Wittig Reaction Introduction This experiment performs a modified Wittig reaction using a phosphorus-containing Hornes-Emmons-Wittig reagent to generate an enolate anion of trimethyl phosphonoacetate instead of a phosphorus ylide. The methyl trans-4-methoxy cinnamate produced is then analyzed using melting point and 1H NMR spectroscopy. Theory The Wittig reaction prepares alkenes from carbonyl compounds by attacking a phosphorus ylide with a nucleophilic carbon atom stabilized by
