Purpose: The purpose of this lab was to go down the a posteriori regulation of magnesium oxide. To do this, we measured the charge of the magnesium before the reaction with oxygen, and because measure it afterwards it had bonded with the oxygen. After the nap of the items were collected, the data was calculated in empirical formula.
Background: The empirical formula of a compound is the exclusively cast ratio of the chemical elements in a compound. For example, the empirical formula of water is H2O meaning for every 1 O atom there are 2 H atoms. The molecular(a) formula tells us the amount of atoms present in a compound. For example the molecular formula of hydrogen peroxide is H2O2. This tells us there are 2 H atoms and 2 O atoms needed for the formula of hydrogen peroxide. The empirical formula would HO, because the ratio is 1:1. To determine the empirical formula of a compound, the mass of each element must be found. The mass is then converted to the amount of moles of the element. Once the mass of each element is converted to mole, the smallest mole is divided by each of the opposite moles to determine the ratio of each element. This will give the consentaneous number ratio of each element.
For example:
Mass of Amole of Amole of A/mole of A= 1 given that mole of A is smallest
Mass of Bmole of Bmole of B/mole of A= whole number > 1
Procedure: An iron ring was fit(p) on a support stand and beared enough room for a etna burner to set below the ring. A clay triangle was placed on the ring with a clean dry crucible set on top the triangle at a slight angle, using crucible tongs to place some(prenominal) items. Using crucible tongs, a cover was placed atop the crucible at a slight angle to allow an opening. The gas to the Bunsen burner was turned on and ignited with a nonluminous flame. The crucible was heated for 5 minutes, while slowly miserable the burner back and forth across the bottom of the crucible. After 5 minutes the heat was shut off and the crucible removed...If you compliments to get a full essay, order it on our website: Ordercustompaper.com
