EMPIRICAL FORMULA OF MAGNESIUM OXIDE NAME: JENNAT-UL-FIRDOUSE BINTI BAKIR MATRIX.NO: CPM76/12C GROUP: D SEMESTER: ONE troth: 01 AUGUST 2012 LECTURER: MADAM KHALINA BT.OSMAN objective lens To determine the investigateal face of Magnesium Oxide INTRODUCTION Magnesium surface is moderately reactive uncomplicated substance. At room temperature , milligram reacts only very soft with oxygen and can be kept for long periods of m without appreciable conversion to oxide .At proud , however, milligram will wake up in an free of oxygen gas, burning with intensely fresh flame and producing magnesium oxide, MgO. In this experiment, we will determined the empirical formula of magnesium oxide,MgO by burning magnesium palm in a crucible with combination of oxygen from surroundings.
