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 aim To determine the investigateal face of Magnesium Oxide INTRODUCTION Magnesium metallic element is moderately reactive uncomplicated substance. At room temperature, atomic number 12 reacts only very soft with type O and can be kept for long periods of m without appreciable conversion to oxide .At elevated railroad , however, atomic number 12 will wake up in an pointless of oxygen gas, burning with intensely fresh flame and producing milligram 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.
