which then proceed to leave the enzyme. We will be investigating an enzyme in this experiment. Catalase to be more specific which is found in the liver. We will compare its action under different conditions with an inorganic catalyst called manganese dioxide. Purpose The purpose of performing this lab is to compare the action of catalase to a non-protein catalyst under different conditions. Hypothesis In section A‚ I hypothesize that the sand will have no reaction but the

Background of the Study Fruits peels of Banana‚ Orange and other fruits are highly rich in potassium‚ ion‚ zinc etc .If these Peel are added in the soil these will become fertilizers. Fertilizers are any organic or inorganic material of natural or synthetic origin that is added to a soil to supply one or more plant nutrients essential to the growth of the plant. Good fertility is fundamental to successful plant growth and the application of fertilizers and manures is an essential graining act

removing silicon‚ sulphur‚ manganese‚ phosphorus and carbon from pig iron by oxidation conducted at a temperature of about 1300oC. • Oxygen required for oxidation is supplied partly by the atmospheric air passing through the furnace and partly by the additions of iron oxide. • Silicon‚ manganese and phosphorus in molten pig iron form SiO2‚ MnO and P2O5. These oxides combine with iron oxide to form a low melting point liquid slag. • As the iron loses its silicon‚ manganese‚ phosphorus and carbon‚ the
