Answer:
The total pressure of the solution is 598.66 torr
while the vapor pressure of the components is vapor pressure of benzene is =502 torr and that of toluene = 96.6 tor
Explanation:
To solve this question, we need to look at the known variables, the unknown variables, and then we select the appropriate relations between the known variables and the unknown
Here we have the temperature of the gases t = 80°C
the pressures of benzene = 753 torr
the pressures of toluene = 290 torr
mole fraction of benzene in solution = 2/3
mole fraction of toluene in solution = 1/3
the unknown variables = composition of the solution and the total pressure of the solution
From here given the known variables and the required variables, the appropriate relation bstween the known and unknown variables is Route's Law
Raoult's relates the vapor pressure of a mixture of gases to the mole fraction of solute gases introduced in the gas solution. Raoult's Law is expressed by the formula: Psolution = Χsolvent1×Psolvent1 + Χsolvent2×Psolvent2+ ... .
where. Psolution = vapor pressure of the solution and
Χsolvent1 = mole fraction of solvent 1
Psolvent1 = vapor pressure of solvent1
Thus we have by Raoult's Law

which is =2/3×753 + 1/3×290 = 502 + 96.6 = 598.66 torr
and composition vapor pressure of benzene is 502 torr
while the composition vapor pressure of toluene is 96.6 torr
Answer:
Rate at which current flows is measured in amperes
Explanation:
The rate of flow of electrons constitutes the current. The electrons flow from lower electric potential to higher electric potential. When there is no potential difference then no electron will flow. The direction of the current and the electron are in opposite direction.
The direction of electron from the negative terminal to the positive terminal. The direction of current is from the positive terminal to the negative terminal.The current is measured in ampere.
The expression for current and the charge is as;
Here, q is the charge, t is the time taken and I is the current.
According to the given problem, Jodi made a list about electric current to help her study for a test. He described that electrons move from areas of low to high electric potential, voltage causes current to flow and movement of electrons is continuous in a current.
But he did error. It should be "rate at which charges flow" instead of rate at which current flow.
Therefore, the option (4) is correct.
The range of potential energies of the wire-field system for different orientations of the circle are -
θ U
0° 375 π x
90° 0
180° - 375 π x
We have current carrying wire in a form of a circle placed in a uniform magnetic field.
We have to the range of potential energies of the wire-field system for different orientations of the circle.
<h3>What is the formula to calculate the Magnetic Potential Energy?</h3>The formula to calculate the magnetic potential energy is -
U = M.B = MB cos
where -
M is the Dipole Moment.
B is the Magnetic Field Intensity.
According to the question, we have -
U = M.B = MB cos
We can write M = IA (I is current and A is cross sectional Area)
U = IAB cos
U = IπB cos
For = 0° →
U(Max) = MB cos(0) = MB = IπB = 5 × π ×
× 3 ×
=
375 π x .
For = 90° →
U = MB cos (90) = 0
For = 180° →
U(Min) = MB cos(0) = - MB = - IπB = - 5 × π ×
× 3 ×
=
- 375 π x .
Hence, the range of potential energies of the wire-field system for different orientations of the circle are -
θ U
0° 375 π x
90° 0
180° - 375 π x
