In most cases, this can take about as quickly as one week or as long as two weeks. Don’t be tempted to rush the process with excess douching – it is important to remember to do this in moderation, as douching too often or using too much apple cider vinegar will wash away not only bad bacteria, but good bacteria as well. 2. Bathing. To run an ACV bath, first make sure your bathtub is clean.
Exercise 2 began with measuring the milliliters needed to fill a coffee mug and measuring the liters in a gallon. Then we went to the sink and filled a graduated cylinder with 70 ml of water and then placed a pencil in the water. Our lab partner, Temi had to use both of her hands to push the pencil in the water in order to completely submerge it, because it kept floating upward. After completing these steps, we then calculated and recorded the volume. Once we finished this, we then repeated steps (a-d) to measure and record the rock 's volume.
There are many solutions to bone disorders, but only of them is really effective A. Let us begin with the easiest and only natural method to increase Vitamin D intake , Sunshine! Now , you are thinking that the solution can’t be that simple, but it is. When our body is exposed to the Sun’s rays , it converts cholesterol into Vitamin D. In fact , Sunlight offers 90% of the body’s Vitamin D. I am not convincing indviduals to resemble a bag of Cheetos. The UK Cancer Research Center recommends getting enough safe Sun exposure daily for 15 minutes between 10 a.m and 2 p.m. A person with a dark skin tone may require 90 minutes, while the elderly require about 30 minutes (Vitamin D, 2015).
Substrate concentration basically means the amount used for the substrate. The substrate in our experiment was 0.1% hydrogen peroxide. The 0.1% is the concentration amount. Just like temperature and pH, substrate concentration can speed the reaction only up to a certain limit. When we mixed pH 3 enzyme tube with substrate tube, we used 0.3 mL of hydrogen peroxide, but if we were to increase the amount, then the experiment would have been faster.
This disproved my hypothesis that Powerade would have the most electrolytes and proved that orange juice contains more and would be better for hydration. It answered my investigative question of which liquid would have the most electrolytes with orange juice coming in first place, Powerade in second place and tap water in last place. I would like to improve the experiment by adding in more variables such as more substances to test and testing at different temperatures to see if the temperature has an effect on the conductivity. I also feel that I would like to get more copper wire to change it after each trial as I think the oxidation of the copper wire caused my later readings to fluctuate and perhaps be inaccurate. I therefore conclude that orange juice proved to be the most conductive and that the oxidation o the copper wires caused some of the later readings to fluctuate but overall I feel that the results were accurate.
One error that could have affected the percent yield is not filtering out all of the liquid from the filter paper in the funnel before setting it off to dry. This would have increased the final mass of the solid, not making it accurate. To stop this from happening again, the liquid could be drained more thoroughly until it fully stops dripping into the Erlenmeyer flask. Another error that could have affected the percent yield is the amount of trials performed. This would have made the results less accurate and made any errors change the final results even more.
To conduct our experiment, we used two 20cm glass containers and fill them up with exactly 200 mL of respective salinities. To ensure that no water velocity is influencing the species tested, the water was settled down before moving our snails into the arena. The glass containers had been marked on the bottom to determine the center of the container. All the snails tested were then placed at the marking and were timed for 1 minute 30 seconds allowing 5 seconds for the snails to acclimate the conditions. The path of the snails was then traced using the acetate sheets and after the allotted time the length of the path was measured using a string and a
Before getting the goldfish subjects, two beakers were filled with 200 ml fish water and weighed. Four goldfish were then collected gently from the fish tank and each two of them were transferred into one beaker. Each beaker along with fish and water was weighed again to determine the weight of each pair of goldfish. For the control group of each trial, the oxygen chamber was firstly filled with 200 ml fish water; after two goldfish along with 200 ml water were transferred into it, it was sealed in order to prevent oxygen exchange with the ambient environment. The built-in probe in the chamber measured the dissolved oxygen concentration in the chamber’s water (mg/L), which could reflect the oxygen consumption rate of goldfish.
6) Next, prepare a 50 cm3 beaker, and pour both reactants into it. Wait for at least 1 minute to allow the reaction to reach completion. Procedure—Post-dilution 1) Use a pipette to fill 3/4 of each cuvette with the new solution from the beaker. Repeat until you have 4 cuvettes with the same solution. 2) Put a lid on each cuvette in order to prevent
Then to 25% and to 12.5% and finally to 6.25% To test its impact on the integrity of the membrane Dependent Variable Change in absorbance Absorbance was measured using colorimeter by taking a sample of ethanol To measure the absorbance of ethanol Controlled Variable Temperature ( 37 Celsius) Use water bath of 37 Celsius temperature. Accuracy Time 1 hour the beetroot cores were put in a distilled water for 10 minutes to make sure all the pigments that are released due to the plasma membrane damage are washed away. Total time for trials is 1 hour. The measurements are taken every 10 minutes. To measure the accurate time when the membrane will break Size and type of the beetroot (size of beetroot) Used the same beetroot for the entire experiment.
Our objective was to pick the best chemical to be used in a hand warm. This chemical had to be cheap, relatively safe, and must raise the temperature by 20oC and no more. We add 6 different chemicals to water we record the inshell temperature and then add one a the 6 chemicals to the water and record the temperature change of the water. We also add cold water hot water together to find how much heat would escape the calorimeter. We found that the calorimeter absorbed 71.1J/oC.
The aim of this experiment was to create Butyl Ethanoate by the process of reflux esterification using 1-Butanol (, 16mL) and Ethanoic Acid (17.4M, 10mL) as raw materials. A catalyst sulphuric acid (18.0M, 2.0mL) was used to offer an alternate reaction pathway and forcing the equilibrium to shift to the right as it is a dehydrating agent result in a greater yield of ester. All reactants were heated under reflux for a total time of 45 minutes, boiling chips were added into the pear shaped flask to encourage even boiling and prevents the occurrence of superheating.
