Citric acid cycle

Draw resonance structures showing all the positions at which the positive charge is delocalized on the aromatic ring in the phenonium ion. If a methoxy group (-OCH3) or a nitro group (–NO2) were substituted in the 4-position on the aromatic ring, how would the stability of the phenonium ion change? Compare methoxy substituted, nitro substituted and unsubstituted, and order them by increasing stability. Explain your answer thoroughly. 2) Benzopinacol and benzopinacolone have nearly…

essential component of a neutralization reaction. When this compound along with an acidic compound (HCl) dissociates, it react and form neutralized components such as water and a salt. This is an ideal mechanism of action for individuals who suffer from acid reflux or heartburn conditions because the excessive HCl that is found in the stomach can be alleviated by ingesting antacid tablets. This experiment explored the effectiveness of different antacids base on the number of HCl moles…

Acid rain results in many ecological effects, with the most severe of these affects being its impact on lakes, streams, and aquatic environments in general. It negatively affects marine life, because acid rain makes waters acidic, causing the absorption of Aluminum; which is a combination that threatens some aquatic animals. As the acidity of water increases, the number of fish and marine animals in general decline. Although, there are some species that are able to survive in acidic water,…

Concentration of Acetic Acid in Vinegar Nalebra Barnett, AAHCA, BSHA University of Central Oklahoma General Chemistry II Lab March 28, 2017 Dr. Lane Whitesell Lab 12. Concentration of Acetic Acid in Vinegar. This laboratory is to determine the concentration of acetic acid in vinegar using molarity and percent by mass of acetic acid in vinegar. This means, vinegar is a crucial solution of acetic acid (HC2H302) in water. Molarity (in mole/L), or mass percent expressed the…

proteins work because they are essential to our health. Without proteins our bodies would not be able to form vital bodily components such as enzymes, and antibodies. A protein is defined as “large molecules consisting of one or more chains of amino acids in a certain order, determined by the base sequence of nucleotides in the base sequence of nucleotides in the DNA coding for the protein” (Medicine net). Insulins formula is C254H377N65O75S6 and its molecular mass is 5808 Da. When the protein…

bottle rocket to go farther. Chemical Reaction Vinegar is an acetic acid. When an acetic acid and baking soda (sodium bicarbonate) are mixed together, three new chemicals are formed, Water (H2O), carbon dioxide (co2), and sodium acetate (C2H3Na02). When one of the three chemical atoms breaks off, it creates the chemical reaction. Vinegar Vinegar is an acetic acid, which is produced by the fermentation of ethanol by acetic acid bacteria (Google.com/vinegar). For the purpose of the experiment,…

Effect of Acid Rain on Wisconsin Fast Plants Introduction Acid rain has become a large environmental problem around the world. This chemically potent precipitation is incredibly common in large metropolitan cities where pollution and smog are prevalent. Acid rain has been known to diminish plant growth or completely kill off populations within the contracted areas of these large cities. In addition to effecting plants, it has also been determined that the pollutants in acid rain, such as heavy…

What is acid rain? Acid rain is a form of deposition in which chemicals with an acidic pH level are taken out of the atmosphere through precipitation. When we pollute the air by burning fossil fuels, we create different chemicals that end up in our atmosphere. A few of these have chemical reactions with the water in clouds, and form (depending on the chemical) sulfurous and nitrous acids. When it rains, this acid is taken back to the ground. While pure water has a neutral pH level of 7,…

nature, it was possible to utilize it as an acid catalyst for the dehydration reaction.4 The use of Montmorillonite K10 is an excellent example of green chemistry as it not only shows the use of catalysts to increase efficiency but also displays a less hazardous form of chemical synthesis. The cyclohexene collected from the first experiment served as the starting material for the next reaction of the cycle in which, hydrogen peroxide (H2O2) and hydrobromic acid (HBr) were combined to generate…
