Oxidizing Magnesium AIM: To determine the empirical formula of MgO RAW DATA COLLECTED: Mass of Mg/g | Mass of O2/g | Mass of MgO/g | 0.12 | 0.07 | 0.19 | 0.15 | 0.08 | 0.23 | 0.16 | 0.08 | 0.24 | 0.19 | 0.11 | 0.30 | 0.21 | 0.11 | 0.32 | 0.23 | 0.09 | 0.32 | CONCLUSION: When a mass of magnesium is burnt in air‚ it combines with the oxygen molecules to form magnesium oxide. The graph doesn’t completely verify the empirical formula of magnesium oxide. There is a slight difference

6.3.4 Leucocytes are white blood cells. Phagocytes are found in the blood and ingest pathogens. One is called Macrophage. They change their cellular shape to surround an invader and take it through the process of phagocytosis. It recognizes if the cell is ‘self’ or ‘not self’‚ by the protein make-up of the cell. The ‘not self’ cells are engulfed and then the enzymes within the phagocytes called lysosomes then digest the pathogens. Phagocytes can ingest pathogens in the blood but also within body
