Does Ethanol To Lose Mass?

Good Essays
When Ethanol is burned the some of its matter is burned causing the Ethanol to lose mass. This is supported by the fact that on average the mass of the ethanol after burning was 2.245 kg less than before burning. Another way we can see that the ethanol was losing mass was was that after 20 minutes we could see a product of the ethanol burning, we could see some water vapor on the box covering the Ethanol and BTB. Because matter can not be created or destroyed to get water in the box some of the matter from the ethanol must have been transferred.
When Ethanol is burned some of its matter is changed to carbon dioxide and water vapor. The proof is shown by the color change the BTB went through. The BTB went from a blue color to a yellowish green

Another thing that went well was that all of the groups got their data on time and followed the directions correctly. One thing we could improve is to reduce scale errors we can check the scales before use, and measure our data multiple times each. Another thing we can do to improve the lab is to measure out the liquid more accurately; the sources of error in our data was most likely caused by differences in the amount of BTB and Ethanol so measuring out these amounts can greatly reduce error. One source of error in the lab was the scales used. The scales are not always accurate, it could be the scales not calibrated or it could be low on battery which can cause large errors in data. On other source of error in the lab was the time the BTB and ethanol were in the container. We used our phones as a timer for the experiment but some groups may have set the timer too late or early, a timer set too late will cause the ethanol to burn for too long which will cause it to loss mass. Another source of error in our lab was the amount of liquid in the containers. If there is too much or too little liquid our measurement will greatly vary. Combustion is a process the relates greatly to what happens in our body. When we consume food it is eventually combined with oxygen to release the energy we need to continue our basic functions. It is important to learn about combustion as it can help us understand more in depth and hard to understand concepts as we go through

    studies of the effect of increased use of corn ethanol on our country and global warming in the United States. When first introduced the production of ethanol from corn was a very popular idea. This favored alternative was meant to reduce carbon dioxide emissions, bring about energy independence, to raise the income of farmers, and to produce more rural employment. Recently, however, corn ethanol has been the topic of heated debate on whether or not it truly does fulfill these goals. This paper will explore…

    A small burette funnel was filled with column packing solvent at mobile phase, high boiling petroleum, in this case hexane (and then 10%acetone hexane mixture), and Alumina as stationary phase. When adding the sand and the alumina they have to be first mixed with the hexanes in order not to disturb the column. The Lycopene is Red- Orange and more attracted to alumina due to its high degree of Unsaturation, which can be expected to be eluted after Yellow-Orange Carotene pigments. And the other pigments…
