Why Is Soda More Carbonated

When the Pop Rocks come in contact with the soda, the gas in the Pop Rocks escape after

The topic of research is, “how fast does an Alka-Seltzer tablet make gas?”. In the experiment, the scientists will be measuring the chemical reaction rates that occur, when 1 Alka-Seltzer tablet is placed in a specific temperature of water. The independent variable during the experiment will be the temperature of the water (degrees Celsius). The dependent variable during the experiment will be, the rate in which gas is produced (in seconds). The constants of the experiment, will be the amount of water used and the Alka Selter compound. The control in the experiment is water. Units used while timing the productivity of gas from an Alka-Seltzer tablet in different temperatures is, seconds.

The project turned out the way it did because the Sprite has more citric acid in it when the other two sodas don’t have citric acid in them giving the sprite more gas to fill the balloon. Coca-Cola and Diet Coke didn’t react as much as the Sprite did because the the Coca-Cola and Diet Coke don’t have citric acid in them when the Pop Rocks react more with citric acid. I was surprised that the Sprite had the biggest amount of gas because it was a clear soda. I thought the Coca Cola was going to have a bigger amount because it is a dark soda and I thought it would have more gas than it did. I knew the diet coke wouldn 't make a lot of gas. If I could improve my project I would have more of a variety of soda’s and pop

In many schools, soda pop vending machines would be the essay way to provide a popular drink such as coke in middle schools even in high schools but can you imagine if this will be continued? For many reasons this product can be the majority of problems in obesity in more diseases why? coke contain a substance harmful for our health, the way how we manipulate this type of drink, well there are some information that infers. For example: it can helpful, coke can be good cleaner for toiler because it can remove stains from vitreous china and other one example, it can remove grease from clothes. In many ways coke can be affected the body of our children. Moreover, water can be a good replacement for coke, it has a lot benefits for many reasons and we can reflect what contradict if is better chose water or coke?

Choice. It is one of the basic human rights everyone should have. However, sometimes the ability to make your own choice is hindered. When New York City Mayor Michael Bloomberg proposed a law to ban large-sized sugary drinks, the city was splintered. Some people believed it was the right thing to do while others disagreed. Limiting the amount of soda a person can purchase is not a good idea, despite its benefits. The regulation itself has a multitude of problems, such as how there are many contradictions, how involved the government is, and how the ban doesn’t really improve health.

The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due to carbon dioxide escaping from solution.

¨Several critics questioned why the city was making proposal on sugary drinks a priority when some city schoolchildren have no physical education classes.¨ (Washington TImes) In New York, Mayor Bloomberg placed a law on the sizes of soda citizens are allowed to get. However, this caused a lot of controversy on whether the ban was good or bad. Despite the amount of people supporting the ban´s choice, the ban does have some downsides on it. It is not a good idea to limit the amount of a soda a person can purchase (or propose the ban) because it's not applying to all, it's taking rights away from people, and itś not a big deal.

A larger sample size could have enabled averages to be resulted, and the experiment could have had several trials until concordant results are attained to increase the reliability. To enhance the accuracy of the results, a machine such as a cheese wire to cut straight along the edge could have been employed that would more accurately cut the cubes and hence reducing human error. This would be efficient as there is a large chance of human error when cutting the cubes by hand as the agar is slippery. Cubes with different sizes could be observed to improve the validity of the experiment. The weight of the bottom of the cubes pushing against the beaker likely caused an error to occur. This could have impact different sized cubes to varying extents. Human error also occurred when the 3cm3 cube had to be repeated as it was initially incorrectly measured. This could have contributed to the results being less reliable as the concentration of phenolphthalein in the agar cube could have been different from that of the other cubes (Unknown, 2008). The method was quite successful and produced relatively accurate results. Next time, a substance such as hydrochloric acid could be used instead of sulphuric

In lab 3, fundamentals of chromatography, the purpose was to examine how components of mixtures can be separated by taking advantage of different in physical properties. A huge process in this lab was paper chromatography, which was used to isolate food dyes that are found in different drink mixes. The different chromatograms of FD&C dyes were compared to identify which dyes are present in each of the mixes. Chromatograms where made for the known FD&C and for the three Kool-Aid samples. The retention factor for each dye was calculated. F or each of the Kool-Aid flavors, 2.0 g was weighed out from the packet and 5mL of water was mixed in with them each. mL of 0.1% NaCl solution was added to 100mL of bottled water. The six chromatography strips

Dr.Pepper is a better soda brand than Coca Cola, because it has less caffeine and better flavors than Coke. Some people agree that Dr.Pepper has more sugar and doesn’t taste nothing like Coke. While others disagree that Coca Cola is a better Beverage. Because if you drank Dr.Pepper you can easily taste a bit of cherry in your mouth having your mouth smell like cherries. According to Debate.org an Investigator RacH3ll3 had mention that Dr.Pepper is a better drink stated,” Dr. Pepper taste better also it has less acid than coca cola. Why would you want to drink something that has more acid. (Dr.Pepper is better than Coke). Also they both has almost the same Ingredients. Dr.Pepper has Carbonated water, high Fructose corn syrup, Caramel color,

The experiment that was done was to figure out “Does the amount of calcium chloride affect the temperature of water?” For the procedure, the experiment asked to record the initial temperature of 75 mL of water. The first trial said to add zero scoops of calcium chloride and stir for two minutes to record the temperature. Once the first temperature was recorded, it must be written from the difference between the initial temperature and the new temperature. Next, it asked to add one scoop of calcium chloride and stir for two minutes and record. Lastly, it told us to repeat the same steps until we had three calcium chloride scoops in the beaker and repeat for two more trials for accurate results. To sum up the experiment, it said to record the average change in temperatures to the class averages to graph a bar graph comparing both of the averages. That’s the procedure on how to conduct the experiment correctly.

Which of the following changes to the experiment will increase confidence in the validity of the result?

A 20ml vinegar is poured in the 250ml bottle. A funnel is used to pour 3g of baking powder in the balloon by sticking the funnel in the neck of the balloon to easily allow the baking powder inside without it spilling on the sides. Slowly but surely the balloon is placed on the mouth of the bottle by stretching it gentle so that it does not tear. A 10cm string is used to tie the balloon on mouth of bottle so that air may not intrude and no air formed be lost. Then the balloon is lifted up so that the baking soda runs into bottle to react with the vinegar inside. Immediately the balloon is inflated by the carbon dioxide formed. The baking soda is kept constant when the experiment is repeated for another different amount of vinegar.

The aim of the experiment was to test different types of soft drink on calcium carbonate marble chips, which were used in place of human teeth, and record what percentage of the marble chips dissolved when it was left in the soft drink overnight. These results will show which of the five soft drinks tested was the most harmful, and the ingredients will be examined to explain why the particular soft drink was the most detrimental to human teeth.

Mental rotation is an important function of visual representation in the human brain when dealing with misoriented stimuli, which is the ability to rotate two and three-dimensional objects in one’s mind. In everyday life, people’s ability to recognize faces and objects from unconventional perspectives stems from their ability to mentally rotate objects. The earliest experiment to research on the concept of mental rotation was by Shepard and Metzler (1971). In the classic experiment, participants were presented with drawings of pairs of two-dimensional figures and three-dimensional cubes that were asymmetrically assembled. Each pair were either
