Changes in the freezing point and boiling point of a solution depend primarily on the number of solute particles present rather than the kind of particles. Such properties of solutions are called colligative properties (from the Latin colligatus, meaning “bound together” as in a quantity). What...

Assertion (A): Larger the value of cryoscopic constant of the solvent, lesser will be the freezing point of the solution. Reason (R ): Depression in the freezing point depends on the nature of the solvent. View Solution The freezing point of cyclohexane is 6.5∘C. A solution of 0.65...
Define hygroscopic in chemistry If one wants to find m (molality) in the freezing point depression equation (and have all other variables), would one multiply or divide the molal freezing-point depression constant by the DeltaT_f? .
What is latent heat in chemistry? Calculate the amount of energy released as heat by the freezing of 13.3 g of a liquid substance, given that the substance has a molar mass of 82.9 g/mol and a molar enthalpy of fusion of 4.60 kJ/mol.� How much energy in kJ is released when 15.3...
On the first single fromThe Low End Theory, Q-Tip and Phife Dawg reminisce about kicking rhymes and practicing their stage presence on Linden Boulevard in Jamaica, Queens. The casual, laid-back mood brings out the duo’s chemistry. Both are on point all the time, but Phife stands out wit...
