The mass would be measured Essay Example for Free
The bargain would be mensurable EssayIntroduction milligram is a metal which need get rid of devil electrons group O is a gas at way of life temperature and it needs deuce electrons and milligram oxide is ionic compound because when they join up they are ions and both elements get under ones skin an opposite charge which creates electrostatic attraction in the midst of them creating a very strong bond between the ii ions, but they only become ions when oxygen takes electrons away from magnesium. 2Mg(s) + O2 (g) 2MgO(s).The conservation of mass is also manifold in this experiment so the theory of conservation of mass is that if I use 48g of magnesium and 32g of oxygen I would get 80g of magnesium oxide, and with this reply the ratio for mass is 2416. What I would expect the jurisprudence to be is MgO because magnesium needs to lose 2 electrons and oxygen needs to gain 2 electrons so the ratio would be 11 so that in every 1million magnesium atoms in that location wou ld be 1 million oxygen atoms. Preliminary Work We would be using a total mass of 150cm, we initially have 200cm but encase of mistakes we would only be using 150cm.Since at that place would be two experiments I would need to divide the amount of magnesium I have in two so each experiment would be using 75g of magnesium. So this means that the durations would need to go up in 5 (5cm, 10cm, 15cm, 20cm and 25cm). Since 5, 10, 15, 20 and 25 all add up to 75 this would be the only luculent method. Using a range this big also allows me to be able to make a parity between the lengths because the results would end up being very different. Possible Formulas for magnesium oxide Formula Mass of atomic number 12 (g) Mass of Oxygen (g) Mass of Magnesium Oxide (g) Point to Plot MgO.) This table shows the plotting point for the graph. All points would be going through point zero (naturally) because if you have no magnesium then it would be unimaginable to get some(prenominal) magnesium oxide b ecause there is no magnesium atoms more oxygen atoms to join up to make magnesium oxide. This also shows the side of each formula so that I pot distich it to my graph for the main experiment and find out what formula of magnesium oxide I have created in my experiment.Formula Ratio/ Gradient MgO 1. 67 Mg2O 1. 33 MgO2 2. 33 Mg3O2 1. 44 Mg2O3 2 Mg3O 1. 22 The function of this graph is so that I could compare the gradient shown on this table to my graph. When I calculate my gradient I would bear witness what formula of magnesium oxide I have created by seeing which gradient is the ambient to my gradient. Timing for reaction The aim here was to find out how long it took for magnesium to burn. Mass (g) date (m) melting pot + hat + magnesium 50. 76 crucible + lid 50. 45 Magnesium 0. 31 Crucible + lid + magnesium oxide 50. 93 29.Crucible + lid + magnesium oxide 50. 96 32 Crucible + lid + magnesium oxide 50. 96 35 Crucible + lid 50. 45 Magnesium Oxide 0. 51 What I knowledgeable from this is that has the mass attachs so does the time it takes for the magnesium to burn. This is because more energy is required to burn more magnesium which means more time would be need to provide it. I can also fall apart that after repeating to see if there was a reaction there was no longer an augment in mass which meant that there were no longer both oxygen atoms joining up with any magnesium atoms.Main experiment List of Apparatus I have used Bunsen Burner Crucible and Lid Digital Balance 0. 01g Goggles Heat Proof Mat Magnesium Ribbon (200cm) kaolin trilateral Tongs * Tripod Safety We used the crucible and lid because it wont crack which means there would be no injury to anyone. If I was to use glass the chanced of and injury would be high. Another advantage for safety with the crucible is that we wont be able to see the light produced from the creation which means there would be no risk of your eyes being damaged.We used a heat proof entanglete so that the table will not get burnt or anything else. We would also use gape because at some point during the experiment we would be lifting the lid to see if the reaction has stopped so using the goggles causes a decrease in glare from the light and it was also used to rule out any particulates from entering my eyes. I also tucked in my tie in my shirt because there was fire from the Bunsen burner and I did not want to get anything easily loose on me to whelm fire so tucking my tie in would lower the chances of injury to me.We also checked the heat of the crucible and lid to if it was cool enough to hold by using the harmless method we h everyplaceed our hands over the crucible and lid to see if any heat was radiating to our hands and we could not feel any feat we would light touch the crucible for half a second to get a better(p) sense of the heat and if it feels cool we would then take it back. Method What Im going to measure is the mass of the magnesium ribbons at different lengths, and Im also going to measure the amount of magnesium oxide it makes.The mass would be measured by a digital balance (0.01g), which was very accurate way of measuring the mass because it can detect up to two decimal places. To make sure its a fair test we took two tests for each length so that we could get an accurate average. We also used a pipe-clay triangle so that the crucible would not experience heat loss (if we were using a gauze) which would affect how often magnesium oxide is produced. We also used the ruler to make sure that the lengths that we used were as accurate as it can be so that the results are fair. How we set up the equipment was that we could have the meat proof mat so that there are no burns around the area or the possibility of fire.The crucible and lid would be placed above the pipe-clay triangle so that the heat would reach the crucible in the right place. The tripod would be used to keep the crucible and lid above the Bunsen burner at the right distance. We would also lift the lid from time to time to see if the reaction has stopped. We can tell if the reaction has stopped because there would be no bright light. Then we would reheat it to see if the reaction has fully stopped. We can tell if the reaction has fully stopped because there would be no increase in mass.Next time I would do two experiments at the same time so that I could get my results quicker. DIAGRAM Length Crucible + lid (g) Crucible + lid + Magnesium (g) Magnesium (g) Average Magnesium (g) Crucible + lid + Magnesium Oxide (g) Magnesium Oxide (g) Average Magnesium Oxide (g) 5cm 4This table shows two results from each length showing the mass of magnesium and the mass of magnesium oxide produced. The two sets of results from each length were then turned to an average so that we can get an accurate figure. I then plan a graph of these results so that I can see a clear trend. The reason why I took many readings from different lengths is because so that I could get different readi ngs for mass so that I can plot them on the graph at different points so that it can give me a line of best fit.
