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
Oil hypothesis accept/reject = Accept, the final result had very little oil in it. b. Vinegar hypothesis accept/reject = Accept, the final result had very little vinegar in it. c. Laundry detergent hypothesis accept/reject = Accept, the final result had a great amount of laundry detergent in it. 3. What affects did each of the contaminants have on the water in the experiment?
(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.
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. This would make us lean toward pentane but we felt strongly that ethyl ether because of the density was a much better test because there is much less human error and the we asked about how do you decide if something is insoluble
a small washer was inserted between the water supply line and the existing showerhead. These worked poorly because pressures were reduced and existing heads did not deliver the desired feeling without the proper pressures. As a result, low-flow technologies got an undeservedly bad rap from which they are still trying to recover. New low-flow showerheads deliver only 1 to 2.5 gallons per minute. Although the amount of water that moves through these fixtures has been reduced, the velocity of the water has been increased.
“Fibers that cannot be digested by bacteria in the large intestines are called insoluble fibers because they do not dissolve in water.” (Grosvenor & Smolin, 2006) High fiber diets can produce many benefits, including higher nutrient absorption levels, and better waste output. Diets that tend to lack in fiber or are high in insoluble fiber tend to cause gastrointestinal irritation and constipation. People that experience these symptoms should consider reviewing their fiber sources, and water consumption
1. Elizabeth Royte’s question “For now, what should we be drinking?” is answered throughout the excerpt by saying that tap water is no better than bottled water. Although bottled water labels say their water comes from the best of the best types of filter, its often a lie and comes from the same type of water that comes through your tap water, according to Royte. She supports her conclusion throughout the whole excerpt with specific example and evidence. Although she has a water filter in her tap water, she believes it is almost the same without one.
On the other hand covalent bonds, the intermolecular forces are very weak and is easily broken,hence lesser heat is required and thus covalent bonds have lower melting and boiling points. Do ionic compounds conduct electricity as: (3 points) Solids? No Liquids? Yes Aqueous solutions (when the ionic compounds are dissolved in water)? Yes Do covalent compounds conduct electricity as: (3 points) Solids?
For example, a plate wouldn’t have worked because it’s flat and leaves no room for the paper towels to fall through. * Bowl of water- Needed to fill the eye dropper to test the thickness of each of the paper towels. I wanted to use a pure substance and wanted to avoid chemicals. * Eye dropper- Allowed for the water to be squeezed out of onto the piece of paper towel. It was very effective because the researcher has control over how much water is being squeezed out.
These conditions are more suitable for ionic bonds. That is why the sucrose and salicylic acid did not have good results, because they have covalent bonds. There were a few sources of error that could be improved in the experiment. For example, when the substance was poured into the test tubes, some of the compound remained stuck to the weighing paper. If we used a stick resistant material for this step, the whole 1g would be accounted for.
