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.? 0.2 0.4 0.6 0.1 0.2 0.4 0.6 0.1 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry No cooling occurs, when an ideal gas undergoes unrestrained expansion, because the molecules Are above the inversion temperature Collide without loss of energy Exert no attractive force on each other Do work equal to loss in kinetic energy Are above the inversion temperature Collide without loss of energy Exert no attractive force on each other Do work equal to loss in kinetic energy ANSWER DOWNLOAD EXAMIANS APP

Stoichiometry A metal oxide is reduced by heating it in a stream of hydrogen. After complete reduction, it is found that 3.15 gm of the oxide has yielded 1.05 gm of the metal. It may be inferred that the Atomic weight of the metal is 2 Atomic weight of the metal is 4 Equivalent weight of the metal is 4 Equivalent weight of the metal is 8 Atomic weight of the metal is 2 Atomic weight of the metal is 4 Equivalent weight of the metal is 4 Equivalent weight of the metal is 8 ANSWER DOWNLOAD EXAMIANS APP
