Doesn't everyone love the sudden eruption of a volcano or watching fireworks on the Fourth of July? There is something about the exciting human reaction to witnessing these explosions. Dropping Mentos candies into a diet soda to see how high the geysers can be a pure excitement. Is it a chemical reaction or a physical reaction? What causes the geyser to erupt? These are some questions that can be answered by a little research on the qualities of Diet Coke and Mentos. Diet Coke has caffeine and acidity, but these qualities of Diet Coke does not affect the geyser. According to Mental Floss (2013, [online]), “You’ll sometimes read that the acidity of the soda is a major factor in the resulting geyser. This is not the case. In fact, the level of the acidity in the Diet Coke before and after the Mentos geyser does not change.” Also, Mental Floss states that caffeine is often cited as something that will increase the explosive reaction with the soda, this is not the case (2013, [online]). The only reason the Diet Coke, or any other soda, explodes is because of carbon dioxide! “Every …show more content…
“A chemical reaction is a change that makes at least one new substance,” according to Richard Spilsbury (2014, p. 8) A physical reaction is when you mix two or more substances and those substances stay the same. This experiment demonstrates a physical reaction called ‘nucleation.’ The rough surface of the Mentos and the carbon dioxide inside the soda combine together to make the soda explode! This is not a chemical reaction because we do not make a new substance. “In physical changes, the original substances do not change chemically. For example, you can dissolve salt in water to make salty solution,” according to Richard Spilsbury (2014, p. 13). In this case, you still have salt and water, not a new product. With Diet Coke and Mentos, you still have these two substances in a much messier form, but you do not have a new
What we choose to drink can affect our health just as much as our eating habits. It is because of this that more and more people are going for little-to-no calorie options rather than high calorie options, which are supposed to be the ideal, chose. But is it? Have you ever had a sip of diet soda or regular soda and wonder what makes this drink so good? Or maybe the exact opposite, like what makes this drink so bad for you? These drinks can feel so refreshing on a hot summers day or even after a long day of work. What’s not so refreshing is what these drinks can do to your body.
An example is the Aspartame found in diet soda. Focusing on diet soda, it is shown that it is linked to even more diseases and causes more side effects than regular soda. Furthermore, “Numerous studies over the past several years have reported links between diet soda and weight gain, diabetes, heart problems, and other health issues. Most recently, headlines sounded alarms about a higher chance of dementia and stroke among diet soda drinkers” (Is Drinking…). The aspartame that is used in the diet soda is the main culprit for diet sodas effects. In fact, “Aspartame accounts for over 75 percent of the adverse reactions to food additives reported to the FDA. Many of these reactions are very serious, including seizures and death” (Aspartame…). Aspartame is a man-made chemical that is made up of aspartic acid, phenylalanine, and methanol. With, aspartic acid making up 40%, phenylalanine making up 50%, and methanol making up 10%. Taking in consideration the phenylalanine in diet soda,” Excessive levels of phenylalanine in the brain can cause the levels of serotonin in the brain to decrease, leading to emotional disorders such as depression” (Aspartame…). With the methanol, that is found in aspartame, it “…breaks down into formaldehyde in the body. Formaldehyde is a deadly neurotoxin… With a recommended limit of consumption of 7.8 mg/day. A one-liter (approx. 1 quart) aspartame-sweetened beverage contains about 56 mg of methanol. Heavy users of aspartame-containing products consume as much as 250 mg of methanol daily or 32 times the EPA limit” (Aspartame…). The effects of methanol are caused by the formaldehyde. “Formaldehyde is a known carcinogen, causes retinal damage, interferes with DNA replication and causes birth defects” (Aspartame…). Overall it is shown that the aspartame that is found in diet soda is linked to a number of diseases
Soda is high in calories. A 20 ounce can of Coca Cola contains 17 teaspoons of sugar and 240 calories…empty calories devoid of any nutritional value. It would take the average adult over one hour of walking to burn off the 240 calories in a 20-ounce soda.Soda increases obesity risk in children. Each additional soda or other sugary drink consumed per day increases the likelihood of a child becoming obese by about 60%. Sugary drinks are connected to other health problems as well.Soda contains artificial sweeteners. While many people opt for artificial sugar to lower caloric intake the tradeoff for your health isn’t so sweet. Artificial sugars are linked to numerous illness and diseases including

Children are particularly attracted to higher levels of junk food consumption and cannot resist beverages that contain high levels of sugar, in their daily lives. Although the popularity of refined sugar has lessened due to an increased understanding of health risks, children still consume far more amounts than is healthy. Children are drawn and addicted to sugar because of the flavour and parents cannot resist providing these snacks for their kids because they are affordable.
It is also found in Diet Coke and other diet sodas. Aspartame is a neurotoxin, i.e., a drug that destroys the brain and nervous system. The molecule has three components: aspartic acid, phenylalanine and methanol. Has been shown that aspartic acid causes brain lesions in animal experiments.
The major ethical issue face by Coca Cola in recent year was concerning sale of hazardous product which affected the health of few consumers including school children. This incident took place in Belgium where Coca Cola beverages found themselves in middle of an accusation of selling poorly processed batch of carbonated drinks which made initially 10 people ill and later the number swelled to 100 which also included school children. This was a contamination scare incident that took place in June 1999. This damaged Coca Cola customer base harming their confidence in the product as it was relating to the production and sale of hazardous product. Two main problems that were identified by the company relating to their production and distribution were ‘‘Off-quality’’ carbon dioxide that affected the taste and odor of some bottled drinks, and an offensive unusual odor on the outside of some canned drinks which were later identified as sulphur odor. This odor has an increasing intensity when the cans were placed in vending machines to sell.
Soda or soft drinks are drinks that contain carbonated water and artificial flavors. There are different soda flavors such as lemon, orange, grapes or cola. They have been developing over the past years from soda water to soda drinks with all these unique flavors. Making sweetener for soda has to have a very large amount of sugar. Some people drink soda every day with every meal, so that means they drink more sugar than their body needs. The sugar in soda is making our body flexible to gain more weight and become fat. Obesity is the main reason for getting diseases, but sugar is the main reason for obesity. Rachele Kanigel believes, “Soda raise diabetes risk and rob bones. They are wrecking our teeth and they are making us fat” (160). Soda has bad effects more than cigarettes because they are everywhere and for everyone. However, if you are under eighteen years old, you cannot buy a pack of cigarettes. Nevertheless, soda is very cheap in price and can be in any vending machine at schools or gas stations. Sodas have been super-sized over the past years from a small can for one person to a bigger size for a family, so they have a very faithful history. Sodas are the main reason for a lot of diseases that have emerged these days and the most important is obesity. Now days, the soda drink industry invested in diet soda to cover or to have a better effect in our body than normal soda. Diet sodas have less sugar percentage, so they are healthier technically but still have side effects on teeth and bones. Samantha B. Cassetty writes, “Daily diet-soda drinkers had a significantly higher risk of heart attacks and strokes than nondrinkers” (46). We satisfy ourselves without thinking, so the soda industry can get more income telling about th...
Every day , Puerto Rico is slowly adapting into the American way of life and is gradually losing what is left of their culture. Perhaps this is because Puerto Rico is a commonwealth of the United States. The poem “ Coca Cola and Coco Frio” by Martin Espada is a great example of someone who encounters the Americanized culture of Puerto Rico. Puerto Rico is struggling to preserve their own identity.
In this experiment, the calcium carbonate was in the form of marble chips. The calcium carbonate reacted with hydrochloric acid when the acid was poured into marble chips. Due to calcium carbonate’s higher reactivity, it displaced hydrogen in the hydrochloric acid. As a result, products of calcium chloride, carbon dioxide and water were formed. As the chemical reaction occurred, the water in the measuring cylinder was displaced and gas bubbles that were blowing out represented carbon dioxide.
Chemical kinetics is the study and examination of chemical reactions regarding re-arrangement of atoms, reaction rates, effect of various variables, and more. Chemical reaction rates, are the rates of change in amounts or concentrations of either products or reactants. Concentration of solutions, surface area, catalysts, temperature and the nature of reactants are all factors that can influence a rate of reaction. Increasing the concentration of a solution allows the rate of reaction to increase because highly concentrated solutions have more molecules and as a result the molecules collide faster. Surface area also affects a
In the present society, people’s schedules tend to be extremely hectic due to either strenuous work schedules or keeping up with school and families. Due to this, numerous individuals do not obtain the recommended eight hours of sleep. On top of not getting enough sleep, they do not eat the proper foods to nourish their bodies. In return, they have a substantial lack of energy. Usually people who do not take care of themselves tend to eventually get more tired by mid-day and as their day goes on. A simple solution would be to go to bed earlier and eat better foods. However, our society has become very lazy, obese, and have started to take the easy way out over the years. Instead of eating better and trying to get more sleep, people drink energy drinks as an easy and fast way to get a boost of energy. Energy drinks have been around since the nineteen-sixties and have become increasingly more popular. There are hundreds of different brands of energy drinks that are sold in grocery stores and gas stations today, and worse than that billions of them are consumed every year. Even though multiple energy drinks are consumed every year, many people are uninformed about; what an energy drink is, what the benefits and non-benefits are, what different types of energy drinks there are, and how mixing them with alcohol can be seriously dangerous.
Soda contains carbonated water and that does not contribute anything beneficial to your body. There are some experts who claim that carbonated water is not nearly as good when it comes to hydrating your body as regular water. You also gain no health benefits from drinking diet soda as it is excreted out through instant urination. Soda is very rich in sugar and the average America can of soda contains nearly 40 grams of it and this is definitely not good for your
When you mix baking soda and vinegar you get what’s called a chemical reaction. A chemical reaction is the process by which one or more substances change to produce one or more different substances (blue book). In this case, you would be mixing an acid and a base. The tw...
Have you ever thought how much soda you consume and how bad it can be for you? Many people will drink soda instead of water, simply because it tastes better. The government should limit the intake of sugary beverages because it can lead to many different problems such as heart disease, obesity, and overall it is an unhealthy life-style. “The average person consumes almost 100lbs of sugar a year, with the single biggest source being soda.” A sugary beverage occasionally would be ok, but drinking it every day would cause problems for you overtime. People drink, more soda than they do water. People should be consuming at least eight 8-ounce glasses a day. Mostly no one will drink that amount of water a day. In today’s society, it can be easy to grab a soda for one dollar and carry on. They may taste better but they are not better for your health. “Sugary drinks include soda, fruit punch, lemonade, and other “aides” sweetened powdered drinks, and sports energy drinks.”
