I think my science project is interesting because chemistry happens in the world around you every day, not just in a lab. I think what you would learn can keep you self and prevent you from playing around mixing thing that could hurt you. You can’t mix all liquids and solids together because it could be harmful. Some liquid can cause a chemical reaction when mixing solids.
What I found that was interesting was how u can take liquid and mix it with a solid and form a gas.
Here’s a breakdown of what’s going to take place when I mix a few things together for my project.
Well, Hydrogen peroxide (H2O2) naturally breaks down into water and oxygen. It is stored in

The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

When they used indigo to make clothing colored. This is a chemical reaction because you have to get the right color into the clothing. Chemistry now is used for all kinds of things like making personal Items. I used a chemical reaction in my experiment because I mixed together dish washing detergent, water, hydrogen peroxide, and yeast. Now you can get a job in chemistry like a chemical engineer.

My hypothesis is that if the baking soda and the vinegar then can potentially mix together with the air that is already in there and start to inflate. Now Alexis is going to talk about why this is a good experiment. Alexis feels like this is a good experiment because of using dangerous air you can use safer chemicals that are safer to your lungs. Now Alexis is going to talk about what she thinks is going to happen during this experiment. Alexis thinks that over time the acids are going to settle down because of how long they been in there if she gives them a long a period of time.

Gummi bears may not be obvious lab material, but in Mary Hershey’s chemistry class, they’re popular fodder for demonstrations. When they go up in flames, students are fired up—to the point of applause. Such displays help Hershey’s Chemistry 1 and Advanced Chemistry classes at State High understand concepts and connect with a challenging subject. “Just last week, we lit methane bubbles to teach them combustion,” Hershey said. “So you can teach chemical ideas through demonstrations, and when the demonstrations are in their head, you can draw on them to help teach and ask questions almost all year.”

Developing a topic for Science Fair will never be easy unless you have a little background about that certain topic. One particular scientist is developing her topic by researching questions she has that revolved around her topic. The scientist will be researching how water temperature can affect the chemical reaction rate between baking soda and citric acid within a bath bomb. The independent variable will be the temperature of the water (mL). The dependent variable will be the chemical reaction rate which is formed by baking soda (g) and citric acid (g).

The experiment page offers more than forty hands-on experiments requiring simple household items to conduct. Each experiment includes an explanation about the experiments, a list of items needed to conduct the experiment, directions, and an explanation of what happens in the experiment and why is it happening. Experiments range from making an egg float in salt water and discussing density to using the static electricity experiment to talk about positive and negative charges. These safe and simple experiments are perfect for starting your lessons.

Everyone knows the simple and easy experiment of vinegar and baking soda, but do you really know how it works. This paper will not only explain what makes these two very different chemicals react, but also what materials you will need to accomplish this easy science experiment. Baking soda and vinegar are two different chemical with two very different uses, they are not really even supposed to be used for a science experiment, take vinegar for example, some individuals use vinegar for cooking. Baking soda has a very different use, it is used for bee-stings. When vinegar and baking soda are combined, the hydrogen ions in the vinegar interact with the sodium and bicarbonate in the baking soda.

Compton scattering is the result of an incident photon with a high energy collides with a loosely bound outer shell electron. The outer shell electron is knocked out of the outer shell and this causes the initial photon to lose some of its energy. This results in a recoil electron and a scattered photon. When the collision happens the scattered photon changes direction and the recoil electron (Compton Electron) is the electron that was once on the outer shell is sent on its own path. The scattered photon’s energy can be calculated by subtracting the recoiled electron from the initial photon’s energy.

2.9. Estimation of Hydrogen peroxide (H2O2) 10 213 The concentration of H2O2 was determined by the method of Okuda et al (38). Fresh leaf 214 sample (0.5 g) was grounded in ice-cold 200 mM HClO4 and was then centrifuged at 215 1200 g for 10 min followed by neutralization of HClO4 of the supernatant with 4M KOH. 216 The insoluble KClO4 was eliminated by further centrifugation at 500g for 3 min.

Other than the theories, there were few things in the class that we discussed was pretty funny and seemed something that I would experiment. The first one is about the hot drinks and how it affects a meeting. After learning that hot drinks influence how likeable one is, I think that it is very interesting how it all works together. As a regular coffee drinker, I think that a sip of coffee changes one’s mood. And, I am curious to observe this effect more.

Rates of Reaction Lab Design What is the effect of surface area on rates of reaction, when magnesium is combined with hydrochloric acid to create hydrogen? Chemical reactions are when bonds between atoms form new molecules. They occur when two or more molecules interact with each other. Substances that react together are reactants, and the ones formed in the reaction are called the products.
