1. Are any of the lab values in Table 1 out of normal range? Are they too high or too low? Her serum creatinine is high. Creatinine is completely filtered from the blood (not as well of a marker for kidney function as inulin because some is secreted‚ but still a good marker of kidney function) and excreted in urine so for her to have more than 0.6-1.2mg/dL in her blood is not normal. Her blood urea nitrogen (BUN) levels are also very high. They should only be around 7-18 mg/dL. Her serum calcium

a gain in kinetic energy. The equation PE = m x g x h supports the fact that as height increases (keeping the mass constant) the energy stored‚ that is‚ the potential energy increases. So when the ball is released the energy stored inside the ball would get converted to kinetic energy of motion which collides with the clay slab resulting in a crater. Thus increasing the height increases the energy stored in the ball and so when dropped‚ more of the energy would be converted to kinetic energy as a

Post-Lab Questions 1. Using the information provided in the Introduction and your observations from Part 1‚ hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint. a. Aqueous Sodium Hydroxide—NaOH (aq) is a very strong base‚ which will completely disassociate into Na+ and OH- ions‚ which would make it a very strong electrolyte. Chemical reaction of the disassociation of Sodium Hydroxide: NaOH (aq)Na+ (aq)+ OH-(aq)

making lab Purpose: To better understand saturated solutions‚ solubility . Analysis: 2. Why was it necessary to heat the water? Be specific. Heating the water allows it to hold much more borax in solution than it could at room temperature. So after the water cooled‚ the ability of the solution to hold the solute inside decreases‚this causes the excess borax in the solution to precipitate in crystal form on the string.When the water at a high temperature‚ water molecules have more kinetic energy

Urea is produced in the liver from excess amino acids. Where are the substances excreted? Carbon dioxide is passed from the cells of respiring tissues into the blood stream. It is transported in the blood (mostly in the form of hydrogen carbonate ions) to the lung. In the lungs the carbon dioxide diffuses into the alveoli to be excreted as we breathe out. Urea is produced by breaking down excess amino acids in the liver. This process is known as deamination. The urea is then passed through the

right to assemble. The women’s suffrage movement of the 1910’s in the United States is a classic example of how sociological change occurs. Portrayed in Iron Jawed Angels‚ the Suffragette Movement was a complex movement within the United States that underwent the five necessary stages needed for sociological change to occur. At the beginning of Iron Jawed Angels‚ a British suffragette Alice Paul along with Lucy Paul were talking with Carrie Chapman Catt in order to receive a permit to hold a parade

Conclusion: The purpose of this lab was to synthesize and purify aspirin. The theoretical yield was calculated to 3.766g. The actual yield of pure aspirin was 2.863g with a yield of 76%. The percent yield indicates that our synthesis was a success but the yield is low and indicates that some of the aspirin was lost during synthesis. Some reasons for loss can result from human error such as loosing product from sticking on the spatula and the Buchner funnel and several weighings. Also‚ when transferring

Digestion Lab Abstract – The purpose of this lab was to understand how different solutions played a role in the digestion protein. By looking at different variables‚ such as temperature‚ and pH we’re capable of understanding just how certain substances functioned and when they didn’t. The data for all labs are clear and concise and give a clear understanding of what solutions work best. All three labs were placed in a warm water bath set at 37’C to stimulate the reaction as if it were taking place
