For example, an experiment similar to this one could be how pressure could affect the time it takes for an Alka-Seltzer tablet to dissolve. Using A flask and rubber stoppers, you can compare the amount of time it takes for and Alka-Seltzer tablet to dissolve in regular room temperature water and room temperature water in a flak but with a rubber stopper stopping the air flow into the flask. This is related to the experiment performed above because the increase in pressure from the rubber stopper stopping the air flow in and out of the flask may affect the time it would take for the Alka-Seltzer tablet to dissolve. Another example of an experiment related to the one performed above is how the amount of water used to dissolve an Alka-Seltzer tablet effects the time it takes for one to dissolve. This also relates to the experiment performed above because it also affects how fast the rate of reaction is.
”(Scientific American) These bubbles are representative of a chemical change and the resulting carbon dioxide should increase the water 's density. This may actually increase the volume of the water taking longer to boil, this difference may be minuscule, even negligible, but there 's a possibility for distinct change in results. This scientific American puts it best “For the reaction to occur,
The Pop Rocks have a very small amount of carbon dioxide in them. When the Pop Rocks are in your mouth they dissolve and the carbon dioxide is released making the pieces of candy explode in your mouth. When the Pop Rocks come in contact with the soda, the gas in the Pop Rocks escape after disolving and the carbon dioxide escapes from the liquid into the balloon. When this happens it causes the gas to make the balloon expand bigger and bigger until the air can escape.
My experiment is elephant toothpaste were foam shoots out of a container or glass. I chose this experiment because I thought it would be fun to see foam shoot out of a bottle. You get to mix curtain substances together to make elephant toothpaste. I thought if I get a small bottle then the most foam should be produced.
Our experiment consists of adding one tablespoon of baking powder to each two cupcakes. There will be ten cupcakes in all and two will be controls, without baking powder. We will figure out which cupcake is the most “perfect” meaning the most fluffy, its circumference and height will be measured. Baking powder contains sodium bicarbonate, dry acid, and cream of tartar. These ingredients chemically changed out mixture into cupcakes.
In western society, the depiction of health usually presides in skin tone. No one wants to be “pale” or “pasty”, so being tan is encouraged like a fashion trend. The tanning salon industry is skyrocketing along with the trend of “soaking up the sun”. It is little known that the “glorious” tan that everyone wants to achieve by sitting out in the sun for a few hours is a defense mechanism designed by the body to stop the harm that ultraviolet rays (UV rays) may cause it. UV radiation has detrimental effects on the human body.
Before Hitchcock’s film Psycho in 1960, many individuals watched the movies from beginning to end as if it were non important. Alfred Hitchcock grabbed the the audiences minds and created suspense, anxiety, horror, and leaving the viewers at the edge of their seats wanting more. Because of this newfound view of films, Alfred Hitchcock’s ideas inspired some of the scariest movies known today which you may know as The Exorcist, Halloween, The Shining, and more.
In Chemistry, a lab was conducted to figure out what a unknown blue substance was. To do this experiment a crumbled up piece of aluminum was dropped into the unknown blue substance. When the aluminum was submerged into the blue substance it started to fizz, turn red and break into tiny pieces. After this occurred the beaker, which contained the aluminum and the blue substance, was placed onto a bunsen burner to be heated. After being heated for a while it turned clear and the red pieces turned into red powder.
How does the amount of baking soda mixed with vinegar affect the volume of gas produced per 10 seconds? A reaction is when (usually) a solute acts on a solvent to create a reaction. An example of a reaction is an explosion, Here we will be using baking soda and vinegar which are our two components which will cause for a reaction to take place. Reactions can be affected by several things such as temperature, concentration and the presence or absence of a catalyst which is a substance which can increase the rate of reaction.
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.
Only the heated solution caused the balloon to expand, suggesting that the increase in temperature is linked to the balloon’s expansion. Furthermore, as the solution was only heated to 60°C, no water vapor was produced to fill the balloon, suggesting the gas was produced solely by the yeast. Thus, the yeast reacted to the heat, supporting the claim that yeast can respond and is alive. Sources of error in this experiment could have included incorrect preparation of solutions. The solutions of yeast, water, and sugar, could have been measured incorrectly causing the control and experimental solutions to be different.
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. Results/Findings When sodium bicarbonate and vinegar mix,
The sweet smell of a vanilla bean cake wafting through my kitchen is probably one of the best ways to begin a Saturday morning. As a result of my absolute love for baking, Sophomore year I created my very own baking business Sugar Rush Baking Company. I am the sole business owner and baker for Sugar Rush Baking Company and it has definitely served as a new beginning in my life. I spend almost everyday in my kitchen baking, decorating and learning new things about being a business owner.
Hypothesis I predict that the more baking powder is added to the vinegar, the
Which will make the dough to rise, and the alcohol produced mostly evaporates from the dough during the baking process. As fermentation occurs each yeast cell forms a centre around which carbon dioxide bubbles form. Each of the bubbles is surrounded by a thin film of gluten form cells inside the dough piece. When these cells fill with gas the dough is increased in size. During rising, if any large gas holes formed, they will be released by kneading.
