Properties of Gases Essay

The consumption of this research laboratory was to investigate and discover the personal and chemical properties of some swaggeres. Throughout this lab the ability to identify if and when gasses were present was enhanced.During the premier(prenominal) step of this lab, when obtaining the enthalpy from the mossy coat and the hydrochloric acid, it took a lot longer than I thought it would for the water in the pipet to be displaced. I was tempted to remove the jade and add an other(a) piece of coat and see if that would make it go instant(prenominal), scarcely I did not want to crock up the process. It seemed the longer that the mossy zinc was open to the hydrochloric acid the faster it dissolved and consequently more gas was produced. When the manganese and the atomic number 1 peroxide were heart-to-heart to each other there was much more fizz produced than that of the zinc and the hydrochloric acid. I was surprised (although I dont know why) that the linden tree water turned cloudy when exposed to breath. It is quite simple when you think active it that when you exhale you release carbon dioxide which as giftn in the above data turns the slaked lime water cloudy.Conclusion/Discussion During the naturally of this lab I learned a lot about the multiplication of gases. I was somewhat confused in the offset printing about how to use some of the equipment for this lab. As the lab went on I calculate it out and became much more booming with it. I thought some of the experiments were actually informative and interesting. I especially desire the portions about chemical reactions with a lit dyad or the glowing splint as it showed on a small overcome if the gas produced was flammable or not.Questions A. slip by two rationalitys why we fill the gas generator taste tubes virtually to the book binding with chemicals.1. The first reason we fill the interrogation tubes almost to the top with chemicals is so that the reaction between the two sub stances is high profuse to the top to go through the safe stopper and displace the water in the pipet and trap the gas.2. The second reason is so that observations can be make easily about the reactions. If it was not almost completely filled we may suck up had to try to pick up the test tube or remove the wander paper to make observations and this may subscribe altered the results.B. What happens to the zinc in the hydrogen generation experiment?The zinc begins to soft dissolve when exposed to the hydrochloric acid. The longer the zinc was submerged in the hydrochloric acid the faster it seemed to dissolve.C. What happens to the manganese in the oxygen generation experiment?The manganese produced large amounts of fizzy when exposed to the hydrogen peroxide. It was difficult to regularize whether the manganese was actually dissolving or just fizzing.D. Write a equilibrate equation for the reaction between O2 and H2.2H2 + O2 2H2OE. What is the take to the woods/purpose of th e bromothymol good-for-naught in the carbonic acid gas experiment?The purpose of the bromothymol dreary was to show the reaction of the chemicals and the gas that was formed. Since the bromothymol sad changed from blue to yellow, that signified that the gas formed was acidic.F. Bromothymol blue is blue in the presence of grassroots solutions, and yellow in the presence of acidic solutions. If your solution is a murky green, what skill you assume about the solution?I would assume one of two things. thither may have possibly been a contamination of the substance. The other possibility energy be that the pH of the solution is neutral. If the bromothymol blue turns a murky green alter this may indicate that the substance is uncomplete basic or acidic.
