Vinegar

interesting because it has transported mankind where they have never been before. That is why this project is on Rocketry, but with small scale rockets. The purpose of this project is to see if a homemade Chemistry Rocket, fuel made of baking soda and vinegar, can equal the endurance and/or the height of a Hobbytown Rocket. Though it is important to know the history of rockets and how they function, and the proper gear to wear even around small scale rockets in order to properly carry out this…

The five white powders were; icing sugar, cornstarch, aspirin powder, baking soda, baking powder. To test it out they mixed each white powder including the mystery powder with four different liquids. The liquids were; water, universal indicator, vinegar, and iodine. For example, when they mix the four liquids with the powder, one of the powders should have the exact same chemical and physical reactions as the mystery powder does. If none of the powders match the…

“An ammonia solution contains only a few ions, and it conducts electricity only poorly. A vinegar solution also contains only a few ions and conducts only a little electricity. But when these solutions are mixed, the ammonia reacts with the acid in vinegar (acetic acid), and they form a lot of ions. This is why the mixture of ammonia and vinegar conducts electricity very well.” (Conducting Solutions, paragraph 5.) In this quote, it shows that mixtures can react and…

between baking soda and vinegar are a basic reaction that can be seen in elementary school classes and even up to college courses( Apple Cider Vinegar, n.d. ). The scientific name of baking soda is sodium bicarbonate, the molecular makeup is NaHCO3. When put into water the molecules dissolve and split into Na+ and HCO3-( Apple Cider Vinegar, n.d. ). Vinegar is a weak acetic when in water it dissociates itself into hydrogen and acetate ions. When Sodium Bicarbonate mixed with vinegar in a…

Environmental Effects on Pillbug Behavior Catherine Liapes October 14, 2015 AP Biology- Pd.9 Mr. Angus Introduction: Before conducting this lab, I researched information on pillbugs and learned that pill bugs are commonly found in damp environments such as piles of leaves, or under logs. Although they are crustaceous, they can still spend their entire lives on land. They are about ¾ inch in length with seven pairs of legs, and multiple antennae. Pillbugs are nocturnal and mainly…

Seashell Lab What does the different concentration of acid do to shells? Due to earth’s increasing carbon dioxide (CO2) rates scientists have shown that it can make shells , skeletons and corals up to one-third lighter in weight. As the ocean water becomes more acidic it lowers the calcium carbonate available to aquatic animals. ‘Scientists have predicted that the increase in ocean acidification could significantly reduce the ability of these creatures to build their casings, potentially…

desire to marry or perform womanly duties results in an accusation of witchcraft, explicating the ways in which women suffer due to societal expectations. Betty is bled by the village doctor in scene six, a process believed to reveal witches, which Vinegar Tom’s production note advises “is one of humiliation rather than torture and Pack is an efficient professional, not a sadistic manic” (134). Later, Betty visits Ellen’s cottage, where she laments, “I don’t know what I’m here for. I’ve had so…

the data produced had small calculations. The percent error showed scattered results. When looking at the table, the percent errors can go from 7.05% to 200% and the reason for the extremely high percents were systematic errors made while measuring vinegar or other measurements. Two of the three deformities in measurements come consecutively after each other: trial 6 and 7. Although three of the percent errors show the high percent, most stayed below 20% which is still not sufficive but it…

& Apparatus: -eye protection -well plate -pipette -small toothpick/ paper clip for stirring -6 white powders: icing sugar, cornstarch, Aspirin powder, baking powder, mystery powder -test solutions in dropper bottles: water, universal indicator, vinegar, iodine solution Safety notes: Aspirin Powder- in case of contact with skin, wash with soap and water. Universal indicator- toxic, in case of contact with skin or eyes, rinse for 15 minutes. Iodine- rinse for 15 minutes in case of contact with…

Ocean acidification is detrimental to calcium carbonate life. As CO2 is absorbed into the ocean, it has a chemical reaction with water and forms carbonic acid, lowering the pH. This acid reacts with the calcium carbonate that many shellfish need to build their homes and protection, forming a different type of molecule, and depleting the ocean’s calcium carbonate resources. While it was obvious in our lab that our four mollusks, wrinkled drill, cowrie, small oyster, and large oyster, were to be…
