Reason®: Respiration is a process in which glucose combines with oxygen and decompose. carbon dioxide and water. This reaction also release some energy. 2)Assertion (A) : The acid must always be added to water with constant stirring. Reason ® : Mixing of an acid with water decreases the concentration of H+ ions per unit volume. 3)Assertion (A): Pure water is neither acidic nor basic. Reason ® : The pH of a solution is inversely proportional to the concentration of hydrogen Ions in it. 4.Assertion(A): The reaction of calcium with water is less violent in comparison to that of sodium. Reason®: The heat evolved is not sufficient for the hydrogen to catch fire. 5.Assertion (A): The balancing of chemical equations is based on law of conservation of mass Reason ® : Total mass of reactants is equal to total mass of product.​
