Stoichiometry Enthalpy change resulting, when unit mass of solid is wetted with sufficient liquid, so that further addition of liquid produces no additional thermal effect, is called the heat of Wetting Complete wetting Mixing Adsorption Wetting Complete wetting Mixing Adsorption ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry The vapor pressure of the solvent decreased by 10 mm Hg, when a non-volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2. What should be the mole fraction of the solvent, if the decrease in vapor pressure of the solvent is required to be 20 mm Hg.? 0.1 0.6 0.4 0.2 0.1 0.6 0.4 0.2 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Pick out the correct conversion. 1 BTU = 252 calories 1 BTU =453.6 calories 1 calorie = 453.6 BTU 1 calorie = 252 BTU 1 BTU = 252 calories 1 BTU =453.6 calories 1 calorie = 453.6 BTU 1 calorie = 252 BTU ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because The strong base and strong acid reacts completely The strong base and strong acid reacts in aqueous solution The salt formed does not hydrolyse Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts completely The strong base and strong acid reacts in aqueous solution The salt formed does not hydrolyse Only OH⁻ and H⁺ ions react in every case ANSWER DOWNLOAD EXAMIANS APP
