Magnesium Oxide Investigation

Extracts from this document...

Introduction

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.

Conclusion

* 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.

    This means to postpone changes in inventory location downstream in the supply chain to the latest possible point. In the key work by Zinn and Bowersox, five different types of postponement strategies are identified. Four different strategies of form postponement (labeling, packaging, assembly and manufacturing)

    Fair test - Use the same Bunsen burner, because if you change the controlled variables, in this case temperature, then the experiment will definitely unfair - Make sure that every experiment has the same amount of time to be burnt and to be cooled down.

    From looking at the graph, I can see that as the concentration increases, the change in mass decreases until it goes under its' starting mass. That is because water diffuses from a region of relatively high concentration to one of lower concentration for example.

    atoms don't have a full outer orbital, electrons had to be transferred. Magnesium is in the second group of the Periodic Table, meaning that it would hold two electrons in it's outer orbital, it's structure pattern is 2-8-2. It "wants to" give away 2 electrons to be able to have

    In most cases, the higher the concentration of the reactants, the faster the reaction. At a low concentration, particles are far apart, have few collisions and a low rate of reaction. At a high concentration; particles are more cramped, making more collisions and a higher rate of reaction.
