Answer:
Vapor pressure of the solution is 22.9 torr at 25°C
Explanation:
When a non volatile solute is added to a pure solvent, the vapour pressure of the mixture decrease regard to the pure solvent following the equation (Raoult's law):
Where vapour pressure of the pure solvent (Water) is 23.8torr at 25°C.
Mole fraction of water is the ratio between moles of water and total moles in solution. The solution has a mole fraction of water of:
Replacing in Raoult's law:
<h3>Vapor pressure of the solution is 22.9 torr at 25°C</h3>
Answer:
Reactive and lose 1 electron
Explanation:
The substances that will conduct electricity is the NaCl solution. Sodium chloride in its solid form do not conduct electricity since the compound is stable and bonded well so there are no available charge carriers. However, when this salt is dissolved in water, it ionizes or dissociates into sodium ions and chloride ions. On the other hand, solid sugar and an aqueous solution of sugar do not conduct electricity since the bond involved in this compounds is covalent, no ionization would occur. When sugar is dissolved in water it stays as a molecule so there will be no available charge carriers to let electricity flow.
