Energy is equal to motion over speed
The purpose of washing the organic product that contains water with anhydrous calcium chloride is to remove water from the organic product, thereby, increasing its purity. Calcium chloride is known to be one of the most effective drying agents together with sodium sulfate and magnesium sulfate. It is especially used for hydrocarbons. It is an inorganic salt that readily takes up the water from the organic product.
Answer: Endothermic reaction
Explanation:
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and
for the reaction comes out to be negative.
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and
for the reaction comes out to be positive.
As the energy of reactants is 180 kJ and that of products is 300 kJ, the energy of products is greater than that of reactants, which means the energy has been absorbed and reaction is endothermic.
