K-, K, K+ (biggest to smallest)
The sample contains 1.00 mol H₂O.
Moles of water = 18.0 g H₂O × 1 mol H₂O/18.0 g H₂O = 1.00 mol H₂O
I believe the answer is option D !!
Answer:
Static electricity is transferred during charging by conduction when electrons from a charged from one object to another object by direct contact. For example, on a carpet, charges are transferred from a person's feet to the rest of his/her body.
Answer:
Vapour pressure of liquid is affected by its TEMPERATURE, TYPE OF LIQUID, ADDITION OF SOLUTES.
Explanation:
Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid. Mathematically, the vapor pressure of liquid is written as:
In (Pvap) = -ΔHvap / R * (1/T) + C
ΔHvap is the enthalpy of vaporization and it is constant for specific liquid, T is the temperature and C is a constant. Temperature therefore affect the vapor pressure of a liquid as increase in temperature can cause an increase in vapor pressure.
The type of liquid also affect the vapor pressure. If the molecules bind to each other strongly in the liquid, it increases vapor pressure to be exerted by the liquid but if the type of liquid is one with weak forces of attraction, the vapor pressure is reduced.
Addition of solute to the liquid increases the boiling temperature of liquids thereby reducing it's vapor pressure.
