Properties of Gases Essay

The purpose of this research science laboratory was to investigate and discover the physical and chemical properties of some blow outes. Throughout this lab the ability to identify if and when ordnanceses were present was enhanced.During the first step of this lab, when obtaining the heat content from the stick-in-the-mud(p) atomic number 30 and the hydrochloric acid, it took a lot longer than I thought it would for the piddle in the pipet to be motivated. I was tempted to remove the stopper and convey an other(a) piece of atomic number 30 and see if that would view it go faster, tho I did not want to interrupt the process. It seemed the longer that the mossy zinc was exposed to the hydrochloric acid the faster it dissolved and thitherfore more gas was produced. When the manganese and the hydrogen peroxide were exposed to each other there was much more fizzing produced than that of the zinc and the hydrochloric acid. I was surprised (although I dont know why) that the lime wet turned dingy when exposed to breath. It is quite simple when you think about it that when you exhale you rid carbon dioxide which as shown in the above data turns the lime water cloudy.Conclusion/Discussion During the course of this lab I learned a lot about the multiplication of gases. I was somewhat confused in the beginning about how to use some of the equipment for this lab. As the lab went on I figured it out and became much more comfortable with it. I thought some of the experiments were very informative and interesting. I especially wish the portions about reactions with a lit match or the glowing splint as it showed on a small scale if the gas produced was flammable or not.Questions A. Give two reasons why we fill the gas reference screen tubes well-nigh to the top with chemicals.1. The first reason we fill the test tubes almost to the top with chemicals is so that the reaction between the two substances is highschool enough to the top to go through the rubber stopper and displace the water in the pipet and trap the gas.2. The second reason is so that observations can be made easily about the reactions. If it was not almost completely filled we may have had to try to pick up the test tube or remove the tissue paper to make observations and this may have altered the results.B. What happens to the zinc in the hydrogen generation experiment?The zinc begins to slowly 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 group O generation experiment?The manganese produced large amounts of fizzing when exposed to the hydrogen peroxide. It was difficult to tell whether the manganese was actually dissolving or upright fizzing.D. Write a balanced equation for the reaction between O2 and H2.2H2 + O2 2H2OE. What is the pop off/purpose of the bromothymol vipers bugloss in the CO2 experiment?The purpose of the bromothymol blue was to show the reaction of the chemicals and the gas that was formed. Since the bromothymol blue changed from blue to colour, that signified that the gas formed was acidic.F. Bromothymol blue is blue in the presence of basic solutions, and yellow in the presence of acidic solutions. If your solution is a murky green, what tycoon you assume about the solution?I would assume one of two things. There may have possibly been a contamination of the substance. The other possibility might be that the pH of the solution is neutral. If the bromothymol blue turns a murky green color this may indicate that the substance is neither basic or acidic.
