Magnesium Oxide Lab Report

magnesium oxide lab report

Calculating the empirical formula: To calculate the empirical formula for when two reactants undergoes a chemical reaction, the following 5 steps should be taken: 1. 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. In the second example, the product is slightly magnesium-rich; the ratio of Mg-to-O is greater than the 1-to-1 expected. Then divide through by the smallest number of moles to get a ratio. The use of magnesium strips ensures the whole surface of the metal is exposed to oxygen.

Be careful around the bunsen burner, even when switched off — they may still be hot! 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. Apparatus Chemicals Eye protection Per pair or group of students: Crucible with lid Tongs Pipe clay triangle Bunsen burner Tripod Heat resistant mat Emery paper optional Access to: Balance 2 d. Using molar masses of both magnesium and oxygen, an expected percent composition, by mass, was found and compared to our experimental results. His name is Robert Maddox and he is he has a physical disability in which he cant walk. Having done this for both elements, you should find the ratio between the two by dividing them both by the smallest number.

In its pure form, it is silvery white, and relatively soft, like ash. To expel the nitrogen from the crucible, we added water to the mixture and heated it up. Record the mass of a clean, dry crucible with its lid. Key experiences: a widower adjusting to the death of his wife, living on his. Compound A substance made up of two or more different types of atoms that have been joined bonded together.

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 ChemLab was used to simulate the reaction involving. Using molar masses of both magnesium and oxygen, an expected percent composition, by mass, was found and compared to our experimental results. The ratio should be close to 1:1 as the formula of magnesium oxide is MgO. Be careful around the Bunsen burner, even when switched off — they may still be hot! To determine systematic error it most obvious in a graph within outlier in the graph.

One major finding during the experiment was that burning magnesium caused its mass to increase as it reacted to oxygen. The cooled crucible and lid was weighed 1st mass to 2dp 9. It is because Magnesium is a highly reactive metal. Record the masses of all the elements present in a given compound. When using a digital device such as an electronic balance, the uncertainty is taken to the smallest digit.

Place the cover ajar to allow the flow of oxygen inside the crucible. It had a shiny and glossy silver lustre with a smooth clean surface, no longer feeling waxy. Data Presentation and Procession: 1. The flame was intensified and the crucible and lid were heated for another 10-12 minutes. The special technology he has is an electronic wheelchair,. The crucible and lid were rinsed with water, dried, and then placed on a clay triangle. Heat the crucible with the Mg present 6.

Do not touch the crucible, lid, triangle, ring, or stand during or after they have been heated. Mean values will be close to the actual value, which helps reduce random error. Cracks are observed in the white magnesium powder. Through the ionic bond between a metal and a non-metal, Magnesium Oxide was the product of two reactive elements Magnesium and Oxygen. To reduce systematic error we should apply the correct methods and be thorough tit the procedure for the experiment, be aware requirements of the lab and take precaution during the lab with methods applied during the experiment.

In this lab, magnesium metal an element is oxidized by oxygen gas to magnesium oxide a compound. The metal oxide was disposed of in the proper marked contained and the crucible was cleaned of any residue and rinsed with deionized water. Magnesium ionises to become a cation while Oxygen ionises to an anion, forming an ionic bond due to electrostatic forces. The surface of the magnesium ribbon was thoroughly cleaned with steel wool and its appearance was recorded 8. Retort stand, ring clamp, clay triangle 5. Heat the crucible in a hot flame for 10 minutes, ensuring that the magnesium is exposed to air but that no solid escapes. Allow the crucible to cool and then add 10 drops of water to convert the magnesium nitride to magnesium hydroxide.
