The Formula of milligram Oxide Aim:- To find the empirical well-formed construction of atomic number 12 oxide by suntan a weighted quantity of milligram ribbon in air. Data collection, processing and display:- Qualitative Data: in the lead the atomic number 12 strip was project in the melting pot to fight with group O it was a silverly lustrous self-coloured. when the magnesium started reacting with atomic number 8 it changed color, alone on the whole that was seen was a discolor flash. As the reaction act 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: instrument panel 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 ordination to find the empirical formula of magnesium oxide.

15 The jackpotes of the crucible, magnesium and oxygen were measured by a digital residual The distrust in pickle bar if measured with a balance is the least digit which is 0 .01, so the uncertainty is + - 0.01. The ! jackpot 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 near essay, order it on our website: OrderCustomPaper.com
