Concentration of acid and reaction time Aim In this experiment, I’m going to find out the relationship between concentration (mole) of acid and carbonate’s reaction. Hypothesis If the concentration of acid is stronger, then the film canister will pop (react) faster. Because the concentration of Sodium carbonate is always same in my experiment, so the factor that changes the volume of carbon dioxide is concentration of Hydrochloric acid. If the concentration gets bigger, the proportion of acid gets bigger, which means there are more particles (molecule) that will bond with other particles (molecule). For this experiment, the proportion to get a CO2 is 2HCl+Na2CO3 = CO2.., which is 2+ Na2CO3 : 1.
The supernatant was assayed for SOD activity by following the inhibition of epinephrine auto-oxidation. 0.5ml of sample was diluted with 0.5 ml of distilled water, to this 0.25 ml ethanol, 0.5 ml of chloroform (all reagents chilled) was added. The mixture was shaken for 1 min and centrifuged at 2000 rpm for 20 min. The enzymatic activity in supernatant was determined. To 0.05 ml of carbonate buffer (0.05 M, pH 10.2) and 0.5 ml of EDTA (0.49 M) was added.
It is important to note that, the higher the blood sugar, the more sugar comes out in the urine. If an individual's kidneys are normal, this usually isn't a problem, but if an individual has diabetes, too much sugar can cause kidney damage. Uncontrolled diabetes can damage the blood vessels of the kidney and destroy the kidneys filters. During Anna Garcia’s autopsy report, the ketones found in her urine, was sign of kidney failure. There was additional signs that Anna Garcia had that supported symptoms of kidney failure, such as necrosis and vomiting.
Synthesis of 3-[5-(4-substituted) phenyl-1,3,4-oxadiazole-2yl]-2-styrylquinazoline-4(3H)-ones was carried out by following steps: Step 1: Synthesis of 4- substituted benzaldehyde semicarbazon51(2) Semicarbazide Hydrochloride (0.1M) and sodium acetate (0.2M) was added and dissolved in 15-20ml of distilled water placed in flat-bottomed flask. In a separate beaker containing required aromatic aldehyde (1) (0.1M) was dissolved in aldehyde free alcohol. This ethanolic aromatic aldehyde solution was added slowly to the solution of semicarbazide hydrochloride. The precipitate, which gets separated, was filtered, dried and recrystallised from 95% hot ethanol. Table 1: Quantity of aldehydes taken S. No.
This happens because enzymes lower the activation energy, as they provide an alternative reaction pathway. The decrease in the energy level aids in making the process happen faster (Jae In Lee, 2011) A catalase is an enzyme, which is found in all living organisms. This enzyme helps to convert hydrogen peroxide into oxygen and water. Chemical actions that happen within the cell produces hydrogen peroxide, which is poisonous and therefore can kill the organism. As a result the presence of the enzyme catalase in the cell helps to quickly convert this toxic substrate into safer products of water and oxygen (All Science Fair Projects, 2004).
. Energy drinks are important for the athletics because they should increase their energy level, and for the ones who don’t get enough sleep at night , they should drink something to active them and rise their alertness. B vitamins group play a good role in energy drinks because vitamin B improves your mood , kill cancer and heart diseases and B12 keeps your red erythrocyte and nerves good and healthy. B6 helps the body in with cardiovascular and protect nerve system function . In addition niacin can heal arthritis
The extended model of Traüble –Haines-Liebowitz. Cholesterol inhibits the water permeability of phospholipid membranes reducing it in nearly one order of magnitude at 1:4 cholesterol:phospholipid ratio. This is concomitant with a reduction in the lateral mobility of the lipids. According to the Haines-Liebowitz-Traüble model, permeability is connected to lateral diffusion . In FTIR spectroscopy, there is a reduction of the value indicating that the connected populations of CH2 increases with the cholesterol ratio, which is totally compatible with the water permeability decrease via the reduction of kinks .
It helps to prevent strokes, heart attacks and blood clot formation. It can be produced from salicylic acid and acetic anhydride, with acetic acid as its by-product. However, salicylic acid consists of the phenolic and carboxylic acid groups which are way too acidic for the stomach lining. Thus, acetylsalicylic acid (aspirin) was refined to become a more effective substitute. Theories In this experiment set-up, acetic anhydride is added to salicylic acid in the presence of a catalyst, concentrated sulphuric acid.
The most critical pH is that of the blood and in order to maintain blood pH, homeostatic control takes place. In homeostasis the organs and fluids will fluctuate to keep the pH of the blood firmly between 7.35 -7.45. This is a very narrow pH range in the blood. If the pH becomes too acidic in the blood : The bones will start to leach calcium and there would be reduced absorption levels of supplementary substances as well as mineral ions. The levels of insulin in the body will upsurge and instead of fat being broken down or metabolized, they will be stored.
An error that occurred was the concentration of the solvent. Since there were two different dilution of the solution, the amount of water used was different, causing a different concentration and producing a different result. The amount of water used should be measured beforehand to reduce the random error and increase the precision of the results. A systematic error may have been the Bunsen burner being on safety flame instead of a blue flame. The long exposure to the low heat evaporated the water, thus increasing the concentration of Sodium Thiosulfate.
If this does occur remove any contaminated clothing and rinse the skin and clothing thoroughly. • Do not inhale chemicals as they can be poisonous. If this does occur take the person away from the substance and take them to a hospital immediately. Method To test my hypothesis, I will add varying amounts of Strontium Nitrate (1-8cm³, adding an extra 1cm³ each time) to 8cm³ of Sodium Nitrate in order to form a white precipitate. I have chosen to use this scale of strontium nitrate because it will give me more results so the graph will be more accurate.
Too much insulin can cause hypoglycemia because the liver produces less glucose and the cells of the body absorb more glucose. Too much glucagon results in too much glucose in the bloodstream because it is not absorbed by the cells and can result in high blood sugar. Not enough insulin causes a rise in the blood glucose level because the glucose remains in the bloodstream. Not enough glucagon results in dangerously low blood glucose levels
Stay well hydrated: This is a good habit in order to avoid stones in kidney for those who have had them previously and want to take preventive measures to remove kidney stones. People living in hot weather and who perform physical work more than average need more fluid intake so as to rehydrate themselves. Citrus intake like orange or lemon juice protect against kidney stones as they contain citrate that stops crystals growing into
Appetite Suppressant A second important aspect of hydroxycitric acid is its ability to suppress the appetite does this by increasing serotonin levels in your body. Serotonin is responsible for a number of regulatory processes that affect appetite. Boosts Metabolism The greatest benefits of Garcinia cambogia is the ability create a more efficient metabolism. Your body uses more energy than it takes in. It causes the body to use fat stores as fuel in your body and thus reduces total fat present in your body.
