This also relates to the experiment performed above because it also affects how fast the rate of reaction is. Like how the temperature affected how long it took for the tablet to react to the water, if there is only one drop water used to dissolve the whole tablet, the time it takes for the whole tablet to react to the water and start to dissolve will be
SYSTEM SUITABILITY THEORETICAL PLATES: A standard solution of 25 µg mL-1of Amoxicillin trihydrate (in triplicate) was prepared and same was injected, then the system suitability parameters were calculated. Theoretical plates per meter Theoretical plates per meter were calculated from the data obtained from the peak using the following expression n = (5.54Vr2)/LWh2 Theoretical plates per column Theoretical plates column were calculated from the data obtained from the peak. n = (5.54Vr2)/Wh2 Where, ‘n’ is number of theoretical plates per meter, ‘Vr’ is the distance along the base line between the point of injection and a perpendicular dropped from the maximum of the peak of interest and ‘Wh’ is the width of the peak of interest at half peak
I think that this is because the company may have wanted miranda to be more gassy and put more carbon dioxide in or the acidic substance of oranges in miranda reacted stronger with the carbon dioxide. However there is a high possibility that our first test for miranda may have a couple of mistakes made since it was a large amount further than its other results(1st test: 3m, 2nd & 3rd test: 1.5m). This may be because we have shaken it too long, measured the results incorrectly, opened the can differently, changed the angle accidentally or since different people were shaking the can… Our method uses measuring distance to find out how well each soda propelled.Our strengths and limits in this method include many things. Strengths include it is accurately measuring the how well the gas and liquid has been propelled, is mostly safe and easy to gather results. The limitations include a large amount like: unable to tell which soda mark is which on the ground, not having the ability to know we are shaking at the same force, not having the most accurate measurer and tool, not able to stop at just the right time, not fully opening the
The extra stretch in the bonds allows the bonds between molecules to relax and shrink a little, giving up their energy. This is equal to cooling.” What this explanation basically means is that superheating the water is equivalent to cooling it. So, when room temperature water is frozen and compared to boiling water freezing, the boiling water has an unfair advantage because it is already more cooled than the room temperature water without being colder, which is even cooler than the phenomenon
So, drinking soda makes you even hungrier/ thirstier. A study was done on children, and proved that drinking one serving of soda per day increased their risk of obesity by sixty percent. Some simple reasons soda is unhealthy are, it is purely empty calories, and you may become addicted. In addition, the high percentages of sugar in soda can cause liver disease, insulin resistance (diabetes), and heart disease. It also may cause Leptin resistance.
The ice which is going from solid to liquid, is absorbing the heat energy from the other ingredients/ice cream. In addition, the ice is sprinkled with rock salt, which lowers the freezing point of the ice. The freezing point being when a substance becomes solid. When the ice melts, even more heat is absorbed from the the ice cream mixture. All of the heat that the ice absorbs makes the ice melt, lowering the freezing point;meanwhile, the ice cream mixture is changing from a liquid phase to the more solid form, ice cream.
Sodium carbonate Overflowed in the molds making it difficult to get out of molds Muffin top Little moist in bottom and middle of molds Very dry on top Some bubbles were made when placed into the water bath Bubbles could be heard popping when in water Took a little bit to disintegrate There were holes when hardening from bubbles Trial 2 crumbled to pieces Trial 4 and 5 were still wet and crumbled and the top came off on Trial 5 An exothermic reaction occurred therefore the water bath became colder Citric Acid and Sodium carbonate Overflowed in the molds a lot making it most difficult to get out of molds Muffin top Little moist in bottom and middle of molds Some bubbles were made when placed into the water bath Trial 5 crumbled to pieces Trial 4 was still very wet at bottom Bubbles could be heard popping when in water There were holes when hardening from bubbles An exothermic reaction occurred therefore the water bath became colder Quantitative: Hydrogen Ion Concentration of Bath Bombs: Bath Bomb
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.
The Mycophenolate mofetil containing nanoparticle was constantly agitated during the dissolution test, collisions among MNP could first disintegrate the structure of the polymer layer. The subsequent fluidic shear devastated the particulate surfaces and caused the release of a drug. As indicated in (Table 7) the cumulative percentage of Mycophenolate mofetil released in the initial 2-4 hr was minor. This suggested that the current formulation could prevent the drugs from the initial burst release. As revealed in (figure 13), the rate of a drug released from MNP was pretty smooth.
The total thiol content was calculated by using ε=13.6x10 cm-1 M-1 Sedlak & Lindsy, 1978). 2.11. Statistical analysis Data were analyzed using StatSoft STATISTICA version 12 software. Differences between the groups were assessed by a nonparametric Mann–Whitney and Kruskal–Wallis tests. Values in the text are means±standard deviation (SD).
