Water Crushing

The objective of this experiment was to learn how water displacement affected density. Another objective was to identify the metals used in our experiments. We used a variety of different metals to test their correlation and to find out if it was negative or positive. I did not expect to learn much from this experiment as we had already discussed density in class and learned that water displacement is basically volume so as it increased the density would have decreased had we used metals of the same mass.

Have you ever wondered what makes Diet Coke and mentos explode and bubble so much? Well here is why it does. There are many reasons why some sodas and colas will not explode as much as other sodas and colas. There is a difference in a physical and chemical reaction when adding in mentos to the different varieties of coke. Researchers have also found different reactions of when submerging mentos into different types of coke. It has also been found on how the parts of the mentos and cokes are broken down to create the eruption.

This is the same process as in distillation that involves evaporating a liquid into a gas phase, then condensing the gas back into a liquid

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

After adding distilled water, alka-seltzer began bubbling extensively, as the two substances react and form CO2(g) and a buffer. Sodium bicarbonate also bubbled mildly, as it reacts with water to form carbonic acid, which then breaks into CO2(g).

The experiment was a success because all of the ultimate goals were completed. The volume of CO2 released from the pop rock reaction was calculated and found at 58 mL. The moles of CO2 was calculated at .00233 mol. The experiment was also a success because it was found that the heat released from combining and eating pop rocks with soda would not kill the consumer unless it was consumed in very high doses. The combination is not dangerous because it doesn't release a large amount of heat. The simulation of stomach acid, pop rocks, and soda reviled that the temperature increase during the reaction is minimal. Some possible errors of this experiment was missing some of the CO2 when the tube escapes the graduated cylinder. To avoid this in the future the tube could be held during the apparatus processes. Another possible error is miscalculation of LD50. In the future calculations could be done more precisely and

Once the carbon dioxide gas begins to produce bubbles, the bubbles shoot to the top of the container, and with more bubbles, the eruption is going to act quicker. The number of Mentos that you put into the diet coke can also make the reaction time much faster (“Mentos Geyser

In my lab,we observed various chemicals and their reaction to water.Their reactions were mostly that they just dissolved with the water,causing the water to turn white.However, some of their reactions were more interesting.One of the more interesting reactions was baking soda.At first the baking soda was chunky yet power like.When water was added however, it turned the water white, and caused it caused the water to bubble.The bubbles started off small, but soon grew in size. After the bubbles died down, there was a small sizzle, and the bubbles sank to the bottom of the specimen tray.The baking soda and a really cool reaction, and I must admit, I popped some of the bubbles with the paperclip. Something that did go wrong was that one of my

To start the soda cans cooled for 20 mins at 5 min intervals. A,B,C,D all started out at 20 degrees. In the first 5 minutes soda can A was in ice and water and cooled down to 19 degrees f. Soda can B was cooled in ice and stayed the same at 20 f. Soda can C cooled in the freezer and also stayed the same at 20 f and soda can D stayed at 20 degrees f.

While thousands of homes are being evacuated in Rosharon, TX, due to flood waters, one man has found a way to protect his property and his family. Using a product that he discovered online, the Aqua Dam, Randy Wagner has been able to keep flood waters away from his home.

You have probably seen the coke and Mentos experiments on the internet and wondered “what causes for the explosion to happen?” You might think that Mentos has something in it that might cause the explosion, but it actually has a lot of sugar on it, with a very rough surface (microscopically). Because of this It give a Mentos plenty of nucleation sites, which means, that the bubbles, or carbonation, has something to attach. Though one might think the explosion from a Mentos dropped into a soda is a chemical reaction but it is actually a physical reaction meaning that all the elements are all there.

The purpose of my investigation is that CanCo is looking to hire a team that can prove it able to effectively solve our technical research problems. I know that pressure can crush things.Pressure is applying force against an item.Air pressure is caused by the weight of air molecule pressing into each other. Temperature is a reason that can causes air pressure because if it's how the molecules will move faster rather if it was colder.The air collides outside which causes the can to crush and no longer the same force inside so the can get crushed. The specific relationship we are exploring is , will the can still crush even though we use another substance rather than just plain water. This interest me because we didn't want to use

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

The goal for this experiment was to see how much of both Sodium Bicarbonate and Acetic Acid it was going to take to fill you a sandwich bag without it exploding. We were going to need to figure out the volume of our bag and get the correct amount of each substance so when it fully reacts the gas formed can blow up the bag. The goal is to get it fully filled without it exploding or not filling up all the way. It’s like mixing baking soda and vinegar together it makes the same fizzy substance in a way along with a gas which most people use for volcanos.

Most people think that the coke and mentos reaction is a chemical reaction, but it is actually a physical reaction. This is because of a process called nucleation. All of the carbon dioxide in the soda is squeezed into the liquid and wants a way out. The carbon is drawn to the porous surface of the mentos, called nucleation sites. These sites provide places for the carbon to form bubbles(eepybird.com).
