This led to an experiment which you can try for yourself and investigate the amount of carbon dioxide dissolved in different beverages and how much can be released at different temperatures. To do this experiment I used a few 16 ounce (454 milliliter) plastic bottles of Pepsi One (at room temperature) and an electronic scale that could hold 0.5 Kg and could be tared.Your chemistry teacher may have such a scale. First I put a bottle of the Pepsi One on the scale and pressed the "tare" button. This sets a 'zero' on the scale so that
1A-Water/MSG: When shaken the water and MSG they mostly dissolve creating an orange gold color, the substance foams at the top from the vigorous shaking action yet still some MSG residue remains at the bottom of the test tube, it was unclear if the reason was because we did not mix it enough or rather we added too much MSG to the amount of water given. 1A-Alcahol/MSG: These two substances barely mix together leaving a transparent yellow tint to the alcohol as well as MSG that was unable to dissolve at the bottom of the test tube. We concluded that this residue was unable to be dissolved in this liquid because the amount of MSG remaining in the bottom of the test tube was around the same amount that was originally placed into the alcohol. 1B- Alcohol/Vegetable Oil: Created a foamy top layer, was semi unclear but as to the best of my observations the alcohol nearly completely dissolved the oil, leaving a foggy appearance to the once clear
Next the freezing point which didn’t eliminate either of them. Next we look at the mass which was 7.465g/ml. This make me lean toward ethyl ether but the masses were still pretty close. Next we move to the solubility of the substances. They are both very soluble in alcohol and hexane so that doesn’t help, but in water ethyl ether is semi soluble and pentane is in soluble.
It is known that chlorine is more electronegative than bromine, and thus chlorine is more reactive, and less discriminatory as to what it will react with, thus making bromine more “selective”. Another pertinent piece of information to look at would be stability. The stability of a free radical increases as the number of carbon substituents increases. Therefore, primary is the least stable and tertiary is the most stable. Also, the more stable the free radical that is left behind, the weaker its C-H bond strength will be.
Problem Which dissolves in water better, salt or baking soda? Hypothesis If salt and baking soda where put in water then baking soda will dissolve better than salt. Abstract The purpose of this project is to determine which material dissolves better in water between salt and baking soda. The hypothesis is If salt and baking soda where put in water then baking soda will dissolve better than salt. One teaspoon of salt and one teaspoon of baking soda were put in two separate transparent glasses of water and then the time of dissolving of each substance were calculated.
However majority of the solid Iodine was left at the bottom of the test tube; which leads to the conclusion that it’s not reactive on water. 2. Solid iodine in 1 mL of potassium iodide is slightly more soluble. The liquid in the small test tube turned a dark brown color. 3.
(With resistance) Air: with resistance, syringe A can still be pushed a little towards syringe B. this is because particles in air are spread out; there are room in between to particles. That is why when syringe A is pressed down, the particles compressed together tightly causing the syringe to move a little before the particles were impacted too tightly for the syringe to move Water: water particles are different from gas particles. Water has very little compressibility. Particles in water are much more compacted together, therefore giving no space for them to compress more. This is the reason why with resistance, syringe A will not move as the particles in water are as tightly compressed together as they can get.
The substance dissolves in water but not in alcohol, is transparent when dissolved in water, is electrically conductive when dissolved in water, dries white, and has a high melting point. Out of the four compounds we received to test, according to the data we collected, sodium carbonate was the one that would work the best as a fixative for the glaze. In the experiment we conducted you will notice that the independent variables were the different compounds, while the dependent variables were the results to the criteria that had to be met. Also, during our research, we found that sodium chloride and sodium carbonate worked better than sucrose and salicylic acid because they have ionic bonds. These conditions are more suitable for ionic bonds.
Even though the results under hexane and toluene are similar, the distances of original mixture, first and second fraction are different from hexane and toluene solvent because they have different polarity. As first fraction containing fluorene, which is much non-polar than fluoreone, fluorene in first fraction is much easier to carry by the moving non-polar solvent. Thurs, as the more non-polar the solvent is the longer distance that fluorene will move. Since hexane has larger non-polar carbon-hydrogen single bond groups than toluene, it is much non-polar than toluene. As the result of this, it can explain why the distance of fluorine in hexane is longer (1.3 cm) than the one in toluene (0.5 cm) and due to less non polar toluene has.
Part C: Density of Sodium Chloride (NaCl) Solution, a sample of NaCl was obtained and measured using a 100mL beaker and a 10mL pipet to determine the concentration of the solution. In order to obtain the appropriate result, a calibration graph and density measurement was used to determine the concentration of the sodium chloride solution. In conclusion, based on the water temperature of 21.8°C in part A’s graduated cylinder experiment obtained, it was determined that the average density was .0973g/mL with a percentage error of 2.5%. When graphed the measurement was equal to Y=0.988x. Part B: The graduated pipet’s average density at 22.3 °C was determined to be 0.9785g/mL with a percentage error of 1.89% shows the graduated pipet to be more accurate and precise.
