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 intention To determine the investigateal face of Magnesium Oxide INTRODUCTION Magnesium surface is moderately reactive uncomplicated substance. At room temperature, atom ic number 12 reacts only very soft with type O and can be kept for long periods of m without appreciable conversion to oxide .At rare , however, milligram will wake up in an extravagance of oxygen gas, burning with intensely fresh flame and producing milligram oxide, MgO. In this experiment, we will determined the empirical formula of atomic number 12 oxide,MgO by burning magnesium palm in a crucible with combination of oxygen from surroundings.
