Green plants use light from the Sun to drive photosynthesis. Photosynthesis is a chemical reaction in which water H2O and carbon
dioxide CO2 chemically react to form the simple sugar glucose C6H12O6 and oxygen gas O2. What mass of water is consumed by the reaction of 6.49g of carbon dioxide?
Generally for simpler salts like sodium chloride, when the salts gets dissolved in water the temperature slightly decreases. But for salts which comes in the form of pellets which are more exothermic increases the temperature of water. The increase or decrease in the temperature depends upon the type of salt that is dissolved in the water.
