Question

Write a balanced chemical equation for process of photosynthesis and the condition of reaction giving physical state of are the substances classify the following chemical reaction as exothermic and endothermic electrolysis of water burning of natural gas decomposition of calcium carbonate burning of magnesium ribbon in air

Answer 1

a)Green plants uses CO2 in presence of light for the photosynthesis process to prepare carbohydrates. This is an endothermic reaction. Reaction given as follows 6CO2 (g) + 6H2O (l) ? C6H12O6 (S) + 6O2 (g) (b) i) Electrolysis of water=Endothermic reaction (ii) Burning of natural gas.=exothermic reaction (iii) Decomposition of calcium carbonate=endothermic reaction. (iv) Burning of magnesium ribbon in air=exothermic reaction.
