ORGANIC AND INORGANIC CONSTITUENT IN ESSENTIAL IN PLANTS AND NUTRIENTS REQUIRED TO PLANTS Organic constituent DEFINITION An organ‚ system‚ or other discrete element of an organism the part of the plant that carries out photosynthesis. EXPLANATION: The chemical compounds of living things are known as organic compounds because of their association with organisms. Organic compounds‚ which are the compounds associated with life processes‚ are the subject matter of organic chemistry. Among the numerous

peroxide‚ as well as the pH and the presence of impurities and stabilizers. Hydrogen peroxide is incompatible with many substances that catalyse its decomposition‚ including most of the transition metals and their compounds. Common catalysts include manganese dioxide‚ silver‚ and platinum. The same reaction is catalysed by the enzyme catalase‚ found in the liver‚ whose main function in the body is the removal of toxic byproducts ofmetabolism and the reduction of oxidative stress. The decomposition occurs

The substance was then disposed of in the waste container provided. Manganese (V) oxide was added to a test tube with hydrogen peroxide and the test tube was then covered. A glowing splint test was then inserted into the test tube. All observations were then recorded. Metals were thrown in the trash while most solution were

------------------------------------------------- Alloy Steel is a metal alloy whose major component is iron‚ with carbon content between 0.02% and 2.14% by mass. An alloy is a metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure‚ while partial solutions give two or more phases that may or may not be homogeneous in distribution‚ depending on thermal (heat treatment) history. Alloys usually have different properties from those

3.MINERALS AND POWER RESOURCES A naturally occurring substance having a definite chemical composition is called a mineral.Minerals are found in certain areas only and not every where. Minerals are formed in different conditions and human activities do not play any role in their formation. Instead only natural processes are involved . Minerals are identified on the basis of their physical properties like colour ‚density ‚hardness and chemical properties like solubility. On the basis of composition
