The Formula of milligram Oxide Aim:- To find the empirical well-formed construction of atomic number 12 oxide by importunate a weighted quantity of atomic number 12 ribbon in air. Data collection, processing and display:- Qualitative Data: ahead the atomic number 12 strip was project in the melting pot to fight back with type O it was a silverly lustrous self-coloured. when the magnesium started reacting with type O it changed color, exactly either that was seen was a discolor flash. As the reaction proceed a white lusty powder started forming around the magnesium and was soon starting to library paste out all everywhere 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: tabularise 1: The atomic pilees in grams with an indecision of + - 0.01 (+ - 0.01/g) of the crucible, magnesium and oxygen in different stages i n the try in pronounce to find the empirical formula of magnesium oxide.

15 The jackpotes of the crucible, magnesium and oxygen were measured by a digital labyrinthine sense The scruple in mount bar if measured with a balance is the least digit which is 0.01, so the uncert ainty is + - 0.01. The bulk 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 of the empty crucible from the mass of the crucible + magnesium oxide ( 31.63 -...If you compliments to get a dear essay, order it on our website: OrderCustomPaper.com
