The Formula of milligram Oxide Aim:- To find the empirical well-formed construction of atomic number 12 oxide by anxious a weighted quantity of atomic number 12 ribbon in air. Data collection, processing and display:- Qualitative Data: in the lead the magnesium strip was project in the melting pot to match with type O it was a silverly lustrous self-coloured. when the magnesium started reacting with atomic number 8 it changed color, however all(a) that was seen was a discolor flash. As the reaction move a white lusty powder started forming around the magnesium and was soon starting to library paste out all everyplace the crucible. The ending result was virtually left over magnesium, that at this point was white, and the white solid powder that cover the crucible on all sides. numeric Data: dining table 1: The atomic pilees in grams with an indecision of + - 0.01 (+ - 0.01/g) of the crucible, magnesium and oxygen in different stages in the try in aver to find the empirical formula of magnesium oxide.

The fate of magnesium was obtained by subtracting the mass of the reverse crucible from the mass of the crucible + magnesium (31.60 - 31.48 = 0.12) The mass of the oxygen is obtained by subtracting the mass of the crucible + magnesium from the mass of the mass of the crucible + magnesium oxide (31.63 - 31.60 = 0.03) The mass of the magnesium oxide was obtained by subtracting the mass o! f the empty crucible from the mass of the crucible + magnesium oxide ( 31.63 -...If you compliments to get a sound essay, order it on our website: OrderCustomPaper.com
