Carbonic acid

Martha Garcia November 10, 2017 Chemical Weathering Background Chemical Weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. It occurs in almost all types of rocks, smaller rocks are susceptible, because they have greater surface area, more common where water is, because water is important to many of the chemical reactions, when water is slightly acidic, which is called ocean acidification. Ocean acidification is…

Dianne Termine Honors Chemistry Period 5 Group: 22 Topic: Dissolving Alka-Seltzer in Different Liquids Due Date: September 30, 2016 (2) Background Research The topic of this experiment is investigating and researching whether different properties in different types of liquids affect the amount of time it takes for an Alka-Seltzer to dissolve. The independent variable would be the amount of liquid being used to dissolve the Alka-Seltzer pill. The dependent variable would be the amount of…

worked out how it did due to additional carbonic acid being created by the reaction. With more baking soda, there is more to be mixed with vinegar, which means more CO2. When explained more in-depth, the double displacement reaction of baking soda(sodium bicarbonate) and vinegar is larger when there is more of the two. When adding more baking soda there is more for it to be mixed with the vinegar. This makes for a greater amount of sodium acetate and carbonic acid. The data teaches that when…

common cause of acidity in water. Photosynthesis, respiration and decomposition all contribute to pH fluctuations due to their influences on CO2 levels. While carbon dioxide exists in water in a dissolved state, it can also react with water to form carbonic acid H2C0. It is mostly inferred that the area is surrounded by lots of eco systemic processes with lots of plant…

Noor Diabi 11AA The life of hydrochloric acid in our stomach Chapter 14 section 1 25/04/2016 Ms. Sara Kassem Sharjah American International School Topic one: Discuss the role of hydrochloric acid in the digestion of foods. Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produced.  Hydrochloric acid (HCl) is a clear, liquid. Which is produced in…

The general aim of the study was to use Pymol to analyse molecular graphics of the isoenzymes carbonic anhydrase (CA) I and II, CA substrates (e.g. bicarbonate), and CA selective inhibitors (e.g., sulfonamides) to determine the relationship between CA structure and function. The specific aim of the study, described in part (ii), was to use Pymol to analyse molecular graphics of CA-I, and II, to determine relationship between structure and function and then use the results to analyse how one of…

Titration is used to determine the equivalence point of a reaction, or the point when the moles of acid are equal to the moles of base in a mixture. Titration is used to determine the concentration of an unknown solution by using an already known solution. This process is important because it is commonly in the medical field. For example, pharmacists use titration in the creation of drugs. In addition, doctors also titration when determining the concentration necessary to give their patients of…

Is Perrier Bad for You? Perrier is carbonated bottled mineral water sourced from the Les Bouillens spring in Southern France. Although the water from the spring is already naturally carbonized, carbonic gas is added to it again as it is bottled. Because of the many health benefits this water promises, it became very popular among Americans who wanted to lead a healthy and active lifestyle. Perrier soon became a widely-used substitute for soft drinks or cocktails and has gained a reputation for…

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,…

hetero-pairs in BLOCK (Plot A) follows similar pattern as Shannon Entropy Method (Plot C). Second, diversity profile for substitution by a given residue follows a characteristic pattern (plot B and D). Positional diversity changes when BLOCK undergoes amino acid substitutions. It is maximum when a position in BLOCK, has maximum and fixed occurrence of a residue (here V, first residue) followed by multiple copies of a second one (here I, second residue) with or without others. When other residues…
