Compare The Reaction Between Mentos And Diet Coke

A physical change includes a change in the material without affecting its composition, such as the physical state change. However, a chemical change includes the change in the composition of the substance. The change in color, formation of a gas or a solid product, and the production of energy are the evidences of a chemical reaction, thus, of a chemical change.

Observations: During the experiment, bubbles were present from the water in the electric water baths that were set at temperatures of 50 degrees Celsius and 60 degrees Celsius. This is because the water has passed its boiling point and began to boil. The glucose powder had a white color. The yeast powder had a mild yellow color. When the glucose solution was mixed with water, it gave a clear color. When glucose solution was mixed with the yeast, it produced a murky yellow color. Bubbles also arose when CO2 was being lost in the experiment under each desired temperature.

A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were taken before, during, and after the reaction. Then the reactants and observations were used to determine the products to form a balanced chemical equation. The purpose of this lab was to learn and answer the question: How can observations be used to determine the identity of substances produced in a chemical reaction?

Though many people will think there is a lot of bad in soda, technically it’s just carbonated water, which is basically “gas that’s called carbon dioxide that has been dissolved under high pressure” (sciencebuddies.org). When one opens a can of soda pop the carbon dioxide in it is released out causing the bubbles in the drink, and the best part for this project is that one can choose their own way to do it, yes they may have to follow what the recipe calls for but they can choose their favorite flavors and their own color for it like if they wanted to they could make a bacon flavored pop but it might not taste the best but the point would be that it would be their own idea.

There is a lot of High Fructose Corn Syrup, the sugar of choice, in regular sodas. People started finding out about how bad sugar is for them and how much sugar was really in their favorite every day drink. Everyone started turning against all of the soda companies and they had no choice but to come up with an alternative. So, instead of using natural sugar or High Fructose Corn Syrup in sodas, scientists invented artificial sweeteners, a way to keep the soda sweet yet contain no sugar. Artificial sweeteners like Aspartame that are added to diet soda are actually worse for us than the sugar that is in regular soda. This was proven by an Osteopathic Physician from the American Colledge of Nutrition who states, "While many of the artificial sweeteners have reportedly similar side effects, aspartame accounts for over 75 percent of the adverse reactions to food additives reported to the FDA" (Mercola).

Objective : To demonstrate the differences between physical and chemical changes while observing the laws of conservation of matter and energy.

The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter.

The diet coke and Mentos experiment has been a favorite of amateur scientists, but how does it work? There have been debates, and scientists have concluded that the diet coke and Mentos is a physical reaction, called nucleation. Nucleation sites are areas that have high surface with low volume. Such places can be your fingerprint, scratches on glass, specks of dust, or even Mentos candy (Eepy Bird). Mentos candies have a pitted surface that’s rough when looked at through a microscope, therefore creating a wonderful place for nucleation to occur. Water molecules like to be next to other water molecules, so if you drop something into the soda, like Mentos, it acts as a site for growth of bubbles. Mentos have a high

A rougher candy surface such as, Mentos, means there are more places for bubbles to grow, or more nucleation sites. (brilliant.org) Surfactants are compounds that lower the surface tension between two liquids. (brilliant.org) Dropping Mentos in Coke is an example of a surfactant. The eruptions happen due to nucleation where the Carbon Dioxide in the soda is drawn to the Mentos. (eepybird.com) The pressure of the bottle is trapping the CO2 inside. The CO2 in the soda reacts to the sugar on the Mentos.

The first rocket I shot went a length of 400cm. The canister rocket leaked vinegar and did not launch until someone touched it. My second time shooting the canister rocket it did not launch due to the leakage of vinegar. Although, another group with the same amount of baking soda had a length of 268cm. The last time I shot the 5mL rocket I got a length of 572cm. This rocket did not take as long to shoot and had less leakage than the other two times. The average of the baking soda rockets in trial A without 0cm would be 486cm, but with the other group's length it would be

Chemical Reactions - Chemical reactions may occur when combining two different materials together, which could result in intense heat, the release of noxious gases, and even an explosion. To avoid a chemical reaction, always clean the holding tank in between jobs that involve different liquids and other material; maintain a record of the materials being

The Mentos and soda react due to nucleation. When the carbon dioxide from the soda mixes with the Mentos, the carbon dioxide is squeezed into liquid it’s looking for a way out. It’s trying to hook on to it can and those things are nucleation sites. Since the Mentos are coated with A TON of sugar that is also contains tons and tons of nucleation sites which causes pressure to build up and BAM It explodes.

Changes in matter occur every day. There are two types of ways matter can be altered; physically and chemically. Physical changes do not change the composition of the matter while chemical changes occur when one or more substances turn into a completely new substance.

A chemical reaction is a process in which elements or compounds react with one another to create new or different substances. There are two parts to a reaction. Those two parts are the products and the reactants. The reactants are the chemicals or chemical compounds that are going through the reaction itself. The products are chemical elements or chemical compounds that are produced as a result of the reactant or reactants reacting. There are four key indications that there’s a chemical reaction is taking place. Those four signs include a change in color and/or odor, formation of a precipitate or a gas, the release or absorption of energy (light, heat, electricity), and if the reaction is irreversible. Along with this information, there are ways to predict the products of a reaction.

The soda ash form experiment 3 was obtained. A 250 ml beaker was obtained and rinsed.
