Magnesium Oxide Investigation

Extracts from this document...


Stuart Moody 11CR Magnesium Oxide Investigation Introduction: When magnesium is heated it reacts with the oxygen that is in the air around it, the magnesium changes from an element to a compound and new ionic bonds are formed between magnesium and oxygen atoms. The new compound is called magnesium oxide and is a white powder; the mass of the magnesium oxide is greater than that of the magnesium. We want to investigate this reaction; the purpose of our investigation is to find out the relationship between the mass of magnesium heated and the mass of oxygen, which has reacted with it. The reaction we will see is between magnesium and oxygen in order to produce magnesium oxide we then want to find a formula for this reaction. Plan: We are going to repeat our experiment a number of times with differing masses of magnesium in order to get a wider range of results which we can then compare and analyse. Our group decided that it would work better if we ran two experiments at the same time, this will give us ...read more.


After this we had to weigh the crucible and record the result, before we weighed it we had to let it cool down because heat can cause distortions on the scales. To make sure that all of the magnesium was reacted we heated it for a bit more and weighed it again, when the two masses were the same we knew that it had finished. The whole reason for us doing this investigation is because we wanted to know the relationship between the amount of magnesium to start with and the mass of gained oxygen, to do this we took the weight of the crucible containing the magnesium oxide and subtracted the weight of the crucible containing just magnesium. When we had done one experiment we tapped out what we could of the magnesium oxide and re-weighed the crucible. We did this process until we had a suitable set of results. Analysis: From my graph I have found that my hypothesis was indeed correct because there is a direct relationship between the mass of magnesium to start with and the mass of oxygen in the magnesium oxide. ...read more.


* The second thing I can think of is that when we took the lid off there was a deposit of magnesium oxide on the underside of the lid; this could have affected the results slightly. I don't really know a way around this one because if we took the lid off then the MgO would just escape. I think that the best way to do it is to put the lid on at the start and when we take it off we could collect the deposits and put it all back in the crucible. * I also think that we left the lid on for too long as we didn't let much oxygen get in and the magnesium needs oxygen to oxidize. If I re-did the investigation I would take the lid off a lot sooner but also taking the above point into consideration. Apart from these slight mistakes, which can always be altered, the investigation on a whole went reasonably well and the way we carried out the experiments was really good and efficient as we got 10 sets of results in order to give us a more accurate graph. ...read more.

  1. Rate of reaction of hydrochloric acid on magnesium.

    All five graphs show as the concentration increases so does the rate of reaction, before carrying out my experiment I knew this would happen as the collision theory has justified this point already, the higher the concentration of an acid the more frequent the collisions will occur therefore faster the rate of reaction.

  2. The role of mass customization and postponement in global logistics

    By holding inventory in a less finished state - that is, postponing final product assembly until actual customer demand is known - companies can more quickly respond to market opportunities and offer greater customization options. However, postponement can require the fundamental redesign of a company's decade-old manufacturing processes.

    - Tongs are needed so you do not touch the hot crucible. - Always stand during this experiment, as there is a possibility of the experiment toppling over, so when it does happen you can quickly jump out of the way.

  2. Finding the Empirical Formula for Magnesium Oxide

    The repeat readings show that for each experiment, the number of magnesium and oxygen atoms reacting was very close, with only a difference of one atom for each test. My experiment was also accurate in the sense that when the crucible was measured, a top pan balance of an accuracy of one hundredth of a gram was used.

    In order to do that, we had to carry out a series of tests. To save time and effort, we didn't have to extract the solid from the evaporating basin. Instead, we were given the two substances. This made it easier for us because it gave us more time to do the tests, since there were a lot.

    The smaller the pieces of solid, the quicker the reaction. The greater the surface area of the reactants, the more particles available for a successful collision. Low surface area High surface area The rate of a reaction is also determined by the concentration of the reactants.
