Carbon monoxide with H at 300 digress temprature in present catalist to form metelon |
|
Answer» The Heat of Reaction is the change in the enthalpy of a chemical reaction. In endothermic reactions, ( ΔH>0 ) thermal energy is absorbed via the reaction. Anther way to view endothermic reactions is that more (thermal) energy is NEEDED to overcome the forces of attraction between molecules and to separate them from one another (the activation energy) than (thermal) released when new bonds are formed. heat+6CO2(g)+6H2O(l)↽−−⇀C6H12O6(aq)+6O2(g) In EXOTHERMIC reactions, ( ΔH<0 ) thermal energy is general with reaction. When new bonds are generated, more thermal energy is released that needed to break bonds in the reactants. In this chemical reaction CaO(s)+H2O(l)↽−−⇀Ca(OH)2(s)+heat(1) the FORWARD reaction is exothermic because energy is released when CaO(s) and H2O(l) combine to form Ca(OH)2(s) . The energy to break the bonds in CaO(s) and H2O(l) on the left side of the equation is less than the energy released from forming the Ca(OH)2(s) on the right side of the equation; the net difference is observed as heat on the right side of the equation.HOPE THIS HELPS YOU!!! |

Explain with an activity that light is necessary for photosynthesis |
|
Answer» AIMTo show experimentally that light is necessary for photosynthesis.MATERIALS REQUIREDA potted plant, black paper strips or Ganongs light screen, clips or cellotape, alcohol, iodine solution, water bath, beaker, burner, water, petri dish, dropper.THEORYLight is ONE of the requirements for photosynthesis. When a part of the leaf is covered from both upper and lower sides with a black paper strip, light will not reach to covered part. Hence, photosynthesis will not take place in covered part of the leaf. On the other hand, as light will be available to uncovered part of the leaf, cells of this region will carry out photosynthesis actively and hence, glucose will be synthesised in the uncovered part of the leaf. In the leaf a part of this glucose is utilised to carry out various metabolic activities and REST of the amount converts into starch. Presence of starch in the leaf, which can be detected by performing iodine test, indicates occurrence of photosynthesis.PROCEDURESelect a healthy potted plant and destarch the plant by placing it in complete darkness for at least 48 hours.After 48 hours, using clips or cellotape cover a part of the leaf of the plant from both upper and lower sides with black paper strips.CBSE Class 10 Science Practical Skills – Light is Necessary for PhotosynthesisAugust 25, 2018 by Bhagya Leave a CommentCBSE Class 10 Science Practical Skills – Light is Necessary for PhotosynthesisBASIC BUILDING CONCEPTSPhotosynthesis (Greek word photos: light; synthesis-, putting together) is the process by which the green plants synthesise their own food (glucose) using carbon dioxide and water as RAW materials in presence of sunlight and chlorophyll. During this process oxygen is released as a by-product. The overall process of photosynthesis can be represented by the following equation:AIMTo show experimentally that light is necessary for photosynthesis.MATERIALS REQUIREDA potted plant, black paper strips or Ganongs light screen, clips or cellotape, alcohol, iodine solution, water bath, beaker, burner, water, petri dish, dropper.THEORYLight is one of the requirements for photosynthesis.
