Magnesium oxide is a white, solid chemical compound that is commonly used as a construction material, a refractory material, and an abrasive. It can also be used as a dietary supplement, an antacid, and a laxative. In this essay, we will discuss an experiment involving the preparation and properties of magnesium oxide.

To prepare magnesium oxide, we can use the following procedure:

  1. Obtain a piece of magnesium metal and a Bunsen burner.

  2. Set up the Bunsen burner and light the flame.

  3. Place the magnesium metal in a test tube, and position the test tube over the flame.

  4. Observe the reaction as the magnesium metal reacts with the oxygen in the air to form magnesium oxide. The reaction will produce a bright white light, and the magnesium oxide will be deposited on the walls of the test tube.

  5. Allow the test tube to cool, and then collect the magnesium oxide by gently tapping the test tube.

  6. Weigh the magnesium oxide and record the mass.

After preparing the magnesium oxide, we can investigate its properties by conducting a series of experiments.

One property of magnesium oxide that can be easily tested is its solubility in water. To test the solubility of magnesium oxide, we can follow these steps:

  1. Obtain a small quantity of magnesium oxide and a beaker of water.

  2. Slowly add the magnesium oxide to the water, stirring constantly.

  3. Observe the reaction, and note whether the magnesium oxide dissolves in the water or remains as a solid.

  4. Measure the temperature of the solution using a thermometer, and record the result.

Another property of magnesium oxide that can be investigated is its reaction with an acid. To test this property, we can use the following procedure:

  1. Obtain a small quantity of magnesium oxide and a beaker of hydrochloric acid.

  2. Slowly add the magnesium oxide to the hydrochloric acid, stirring constantly.

  3. Observe the reaction, and note any changes in the appearance of the solution.

  4. Measure the temperature of the solution using a thermometer, and record the result.

By conducting these experiments, we can gain a better understanding of the properties of magnesium oxide and how it behaves in different conditions. These results can also be used to predict the behavior of magnesium oxide in other applications, such as its use as an antacid or a laxative.

In conclusion, the preparation and properties of magnesium oxide can be investigated through a series of simple experiments. By understanding the behavior of this compound, we can better utilize its many applications in various fields.

The color that it appears is white or colorless crystalline solid. Weigh the completely cooled crucible containing magnesium oxide with the lid carefully. Simple computational simulations are created and used based on mathematical models of basic assumptions. Because the substances were transferred so quickly and taking into account the number of seconds that it took to replace the thermometer to begin recording data again it is possible that energy was either lost in the transfer or energy was lost before the recording was actually able to begin. Doses expressed in magnesium oxide salt. On both accounts though if you do need to prod the magnesium in that time you may be letting a lot of smoke out as the lid would obviously need to be off the crucible and so this would also need to be taken into consideration.

Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. How do you find the heat of formation? This gives the number Of moles Of each. A few calculations after that will help determine the formula. This experiment had demonstrated the basic chemical reaction and the change in states between elements in order to form a stable ionic compound. When this temperature change is multiplied by the heat capacity, the amount of heat needed to raise the temperature of a body by one degree, we can measure the change in converting our initial components reactants to their respective products. A new substance will be made in the form of smoke and the new formula will be MgO.

Middle Keep opening the lid after a few minutes for the oxygen to come in and react with the heating magnesium 11. Patients complain of nonspecific symptoms such as fatigue and weakness, and hypokalemia can predispose to intestinal ileus. The formula provides the simplest positive integer ratio of elements in a compound. The Chemical changes I expect to take place are that a new substance will be made and a new formula will be formed. So based on these charges, we would predict that the formula of magnesium oxide should be MgO one +2 ion combined with one -2 ion.

Evaluation for depressed deep tendon reflexes, periodic monitoring of serum magnesium levels, and dose reductions from 50% to 75% are recommended. This creates a pattern of endlessly repeating lattice of ions they do not exist as a free unit of atoms but in crystal lattices with repeating ions in specific ratios which is why empirical formula is used as a form of identification for defining an ionic-bonded substance. The tripod and pipe clay triangle were used to keep the crucible safely above the heat. The controlled variable is that the Magnesium used is possibly from the same ribbon and after being cut into lengths was stored in the same way in plastic containers. A typical apparatus is illustrated in figure 1 2. It had a hazy, dark metallic sheen to its appearance.

After the experiment of combusting Magnesium, the residue in the crucible is observed to be in a fine white powder form of Magnesium Oxide, an ionic compound. Weigh the crucible with the lead, 15. A Bunsen burner was lit to a high temperature blue flame with a flint lighter and placed directly under the crucible. Note that oxygen atoms are found in MgO individually…. Therefore the ratio will have more magnesium and less oxygen than it should have been. Theory: The purpose of this lab was to confirm the chemical formula of Experimental: 1. At the melting temperature the equilibrium vapor pressure is 0.

Moles of oxygen reacted The number of moles of oxygen atoms contained in 0. My predictions for this experiment were right as the results show that the more Magnesium ribbon that was used the more oxygen was needed to react with it and so the gradient was steady at about a 450 angle gradually increasing in mass as the Magnesium mass increased. The theoretical result for the combustion product of Magnesium and Oxide is MgO, which in comparison to the experiment result of MgO was proven to be the same. This indicates that the growth is isotropic and problems that are associated with the formation of a cellular structure under the conditions of constitutional supercooling do not really apply to this material. Scientific questions arise in a variety of ways.

Conclusion: My hypothesis was proved correct at the end of the experiment, as the magnesium oxide mass was greater than the magnesium ribbon at the start of the experiment. Video of Reaction of Magnesium with Carbon Dioxide Video 2: See reaction 5 in the Chemistry Comes Alive 3 video from our 10. Percentage Composition of Magnesium Oxide Aleshia Otieno Mr. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide MgO. What would be the % Mg in this product?? Divide mass by the atomic mass for each element. Each measure of Magnesium was only tried once and each measurement was done by an individual and so this may account for the random errors in our findings as shown on the graph, but overall our results were fairly evenly spread.

Neither determination is free of interference. These patients are likely to be refractory to replacement of potassium alone without treating the hypomagnesemia as well; hence, magnesium levels should be checked and repleted in all hypokalemia patients. In its pure form, it is silvery white, and relatively soft, like ash. It is believed that Mg may prevent the wave of brain signaling which produces the visual and sensory changes that are the common forms of aura. Place on top of clay triangle 5.

Since oxygen is a Group 6A element, it forms -2 ions: O2-. The concept of stoichiometry mole equation leads to finding the empirical formula of magnesium oxide. The amount of MgO formed will be dependent on the amount of Magnesium ribbon used, along with avoidance of human error i. By placing the Magnesium in the crucible in different ways it may affect how much oxygen can get to the ribbon, if it is coiled up for example it may need to be prodded and moved to allow all the Magnesium to have exposure to the Oxygen whereas the smaller strips may be more exposed without as much intervention. Our line of best fit was slightly below the theoretical line of best fit for this experiment and I mainly believe this could be due to a systematic error such as the scales we used not being precisely accurate. I made the test fair by taking the measurements of the crucible and lid and keeping them the same so that I can compare the results between the Magnesium and Oxygen. Small amounts of aluminum and iron may be masked with triethanolamine.
