If only one reactant is increased, then the chemical reaction will only produce a certain amount of products after the limiting reagent is used up, and in this experiment, the most mass the reaction could produce was 0.4 grams. Although we kept adding calcium chloride, not adding sodium hydroxide in the same proportions will not yield more product, which is the main goal in conducting this lab. We should have seen a plateau at 0.4 grams to show that the limiting reagent inhibited further Ca(OH)2 production, but we made several mistakes in our experiment, which made the data unusable to conclude. Once again, the data is polluted, so these number are not accurate, but it is the data our group has to work with. The theoretical yield should have been more than the actual yield, and the percentages should have been less than 100.
(see table #2) The mixture with the bean water caused the solution to not be as concentrated, limiting the amount of oligosaccharides that the alpha galactosidase can break down, therefore resulting in a small amount of glucose concentration. The highest stand standard deviation is at 4 mL of alpha galactosidase, which is 185.742. The lowest standard deviation is at 0 mL and 1 mL of alpha galactosidase, which is 0. Since error bars are not all overlapping, it shows that there was a significant difference (see figure #3). However, the R squared value is 0.929, meaning that it is close to fitting the line of best fit.
Diesel engines outperform and produce less emission rates on Earth than gasoline engines. On the other hand, gasoline engines cost less to run daily. With the EPA making diesel emission standard more stricter, the emission rate for diesels have decreased. Also with different equipment being installed to diesels, the power has increased too. How much have the EPA standards lower the emission rates?
By adding the cobalt additive, the phosphate crystals formed on the zinc get more uniform and contain less porosity. The densest coating of the phosphate coating samples was obtained with 3g/lit ions of cobalt. However, the excessive addition of additive (4
Multicomponent inclusion complex also reduces amount of βCD required for complexation, thus reducing the formulation cost (16, 17). In our previous study it has been reported that the βCD alone increases the solubility of DOM by 2.2 folds where as ternary complex comprising of DOM, βCD and citric acid (CA) increases the solubility of DOM by 76 folds (18). Riebero et al. (2004) have reported that the quaternary inclusion complex (QIC) of a weakly basic drug such as vinpocetine, βCD, tartaric acid and water soluble polymers enhances the solubility of vinpocetine than the ternary complex involving vinpocetine, βCD and tartaric acid. It was found that the polymers increased the stability constant of QIC by co-complex formation (19).
Unfortunately, after performing this experiment, we were not able to support this hypothesis and come up with a conclusion. A possible explanation for why there was no mitochondrial activity observed in the boiled corn kernels might be because increasing the temperature would disintegrate dehydrogenases and thus they wouldn't function as efficient or they
The contraction makes the Z discs closer to each other and increases density of filaments, therefore reduces chewing ability. After slaughter, but before the rigor mortis, it is still able for filaments to slide over each other. However, after rigor mortis, the two types of filaments become fixed. Because of some reason by which the rigor mortis comes right at the time of contractile state, the meat will be very tough. It results from not enough ATP to operate the calcium pump, so the calcium concentration in sarcoplasm begins to rise, and muscle relaxation fails to start.
The atkins diet, the military diet and the pineapple cleanse are just some examples of the great variety of ways to lose weight in a short period of time. As said before, fad diets do generate visible weight loss but they do not keep this weight off. They consist on a strict dietary regimen with almost no deviations permitted that lead to weight loss because the calorie intake is reduced (Sarafino). When calories are reduced, the body has no source of energy other than fat. It starts to burn all the extra fat located in the thighs and abdomen consequently reducing volume and weight.
This was because the bigger the size of the leaf, the more catalase is present. Hence, each leaf was cut to the dimensions 2 by 3cm so as to ensure that the only factor affecting the rate of enzyme reaction was the concentration of hydrogen peroxide and not the amount of enzymes present. The third control variable was the species of brassica rapa leaves only as the species of leaf used affects rate of enzyme reaction. This is because different species of leaves have different amounts of catalase. Hence, if the species of the leaf is different, the results will be inaccurate and unreliable as the rate of enzyme reaction will not be purely based on the concentration of hydrogen peroxide, but will also be dependant on the amount of substrates in the different leaves.
The diet plan that limit the carbohydrates and help to reduce the risk of diabetes and obesity is the low-carbohydrates diet plan. By using the low-carbohydrate diet plan, it helps to increase the HDL levels, decrease blood sugar and pressure levels and decrease the triglycerides present in our body. In a short period, people lose weight very quickly by following the low-carbohydrate diet. This can be seen that, CL loses 1.5kg after one week, which the reduction in weight is relatively fast. According to Krebs et al.
