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.
