Viscosity of the formulation was determined using Brookfield Viscometer. The viscosity of the formulation increased with an increase in Sodium Alginate and Pectin concentration. This phenomenon is a consequence of increasing chain interaction with an increase in polymer concentration. This change in viscosity is proportion to the change in concentration and polymer ratio. The buoyancy lag time in simulated gastric fluid (0.1 mol L-1 HCL, pH 1.2) varied with the formulation variable.
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.
Did you know that saltwater is more dense than fresh water? The salt adds a lot more volume. Therefore salt water has more volume than freshwater. Volume is the amount of space or a measurement of mass. Volume is mainly used to measure liquids.
This proves that chemical stress affecting the cell membrane of the beet was caused by the adding of ethanol in higher concentrations because the alcohol affects the cell membrane by attaching the cell membrane like water does cause it the changing shape and create a hole big enough for more alcohol to get in. This also causes alcohol to damage the vacuole causing the betacyanin to get released and the red pigment to get transferred into the ethanol around the beet. In conclusion, the chemical stress affected the cell membrane of a beet cell, because of the higher amount of ethanol added to the beet caused the cell membrane to change shape which resulted in the betacyanin being released from the cells. These results affect me because I have always wanted to understand why anything that the beets get mixed with, food, water, bowls, etc, will turn
Practical Report- Diffusion in Agar Cubes Sabrina Turtur- Stage 1 Biology Introduction Diffusion is the movement of particles (atoms, ions or molecules) from an area in which they are in higher concentration to areas of lower concentration. It continues until the concentration of substances is the same throughout. The act of diffusion occurs in respiration, photosynthesis and osmosis. Without it, cells would not receive the nutrients they need to resume stability. Commonly, molecules found within a liquid or a gas will diffuse more efficiently , however, the process of diffusion is altered by a range of permeability, such as the size of the diffusing molecules, the composition of the molecules and the surface area to volume ratio of the substance that the object is disseminating into.
Sulphuric acid One of the most important chemicals used in the industrial revolution was sulphuric acid (H2SO4), as it had many different uses in textile and metallurgical industries. Due to its importance, it was in high demand and the amount which could be produced was constantly trying to be improved.It was during this period that a scientist by the name of John Roebuck discovered that this chemical could be produced at a much larger scale than once thought. He did this by making small changes to the production method. Up until now the chemical had been produced in glass bottles by reacting sulfur with potassium nitrate, or saltpeter as it was more commonly known, with steam. The potassium nitrate acted as an oxidizing agent, oxidizing
The result will either be the same or lower than the Red Bull. Chart representing average heart rates: - Female (bpm) Excellent: 61 -65 Average: 74-78 Poor: 85+ - Male (bpm) Excellent: 56-61 Average: 70-73 Poor: 82+ Conclusion: Red bull increased the heart rate drastically but did not make the swimmer swim much faster thus Red Bull would not be a good stimulant for speed
Another way to improve this experiment would be to allow the fermentation reaction to happen for two weeks instead of one week. The longer the reaction can occur, the higher the yield of ethanol will be. The last way to improve this experiment would be to centrifuge the product, using a micro centrifuge. If this step was done then the supernatant would be clear, pure and ready for fractional distillation. Also, if this was done, more ethanol may have been
For instant, when comparing two unicellular organisms, such as yeast and bacteria, S. cerevisiae shown to have a much slower proliferation rate (100 minutes per generation) as compared to E. coli, which proliferation rate is 15 - 20 min per generation (Herskowitz, 1988). In addition, the proliferation rate and doubling time would increase proportionally as the size of an organism increases. Nevertheless, there are many other factors that would influence the proliferation rate of a cell, including the chemical composition of a media, environment, water sources and water availability, carbon sources, nutrient sufficiency, pH and et
Hence, a nice long entered Testosterone should be run about 2 weeks longer than deca, to prevent having a lag in time when the Deca is not producing anabolic side effects, yet is still suppressing your natural Testosterone levels. A particularly aggressive PCT be run after your cycle; nolvadex, HCG, and perhaps clomid should all be utilized in an effort to restore your natural hormone levels as quickly and efficiently as
