Answer:
6.52 × 10^14 Hz
i don't know if that's right tbh
When a non volatile solute is added to a solvent, the vapor pressure of the solvent will decrease.
Vapor pressure is a colligative property. Which means that it will be affected by the number of particles of solute.
The relationship between the concentration of the solute and the vapor pressure is given by Roult's Law
ΔP = Xsolute * P, where ΔP is vapor pressure lowering, Xsolute is the molar fractionof the solute, and P is the vapor pressure of the solvent.
Then lets find Xsolute
X solute = # moles solute / # moles solution
# moles solute = 75.0 grams / molar mass
molar mass of C12H22O11 = 12*12g/mol + 22*1g/mol + 11*16g/mol = 342 g/mol
# moles solute = 75.0/342 mol = 0.219 mol
# moles of solvent = grams of solvent / molar mass of solvent
# moles of solvent = 180 grams /18 g/mol = 10 mols
Xsolute = 0.219 mol solute / (10 + 0.219) mol solution =0.0215
ΔP = 0.0215*26.7 torr = 0.57 torr
Answer= 0.57 torr
Global warming
Carbon dioxide is released into the air, causing global warming.
Answer:
Δ
= -461198.3 J
Explanation:
Gibbs free energy is defined as the energy associated with a given chemical reaction which can be used to do work. Firstly, we need to figure out the chemical equation for the given problem. For the given problem, the chemical equation is:
⇒
⇒
The addition of the two 
gives the 
of the equation, i.e. -1.18-1.21 = -2.39 V.
Then, using the equation for Δ, we have:
Δ = n*F* = 2*96485*-2.39 = -461198.3 J
