we had three flasks all containing varying temperatures of water(H20). One with cold water (4°C)‚ one room temperature (21°C)‚ and one with hot water (44°C). In each flask‚ we dropped one tablet of Alka-Seltzer‚ all within 0.008 grams of each other‚ into the three separate beakers and the duration until the tablet dissolved. The results showed a large change in the average reaction rate between the different temperatures. The cold water took 256.91 seconds to dissolve and had

Alka-Seltzer tablet was added‚ quickly covered with a cap and was observed until the film cap popped off. The time was then immediately recorded and the procedure was the repeated three times each with whole and crushed Alka-Seltzer tablets. Then results from three fellow classmates’ experiments would be recorded and added to our own results. The hypothesis was that more surface area exposed and smaller volume would result in a faster chemical reaction of the material. Since the Alka-Seltzer tablet would

Some people think that it is a bad idea to replace tablets with textbooks and some other people think it is a good idea. There can be many opinions over this topic‚ so let’s explain why we shouldn’t have them replace our textbooks.The first reason that we shouldn’t have them is because if you lose them it’s it will have a critical impact on school. One of the reasons it could have an impact is because we could lose everything you had on it. Not only that but they also cost a lot of money. If we

By crushing the Alka-Seltzer tablets to different extents‚ we were able to determine the effect of surface area on the rate of reaction. Trial 1 was the control and a full Alka-Seltzer tablet was placed in water at room temperature‚ 26.0 °C. It took 40.40 seconds for the tablet to react. Trial 4 was a crushed tablet reacted in water again at room temperature. It took 35.42 seconds for the reaction to end. Lastly‚ Trial 5 was a powder of the tablet reacted in water at room temperature once
