Answer:
A. They both require a human to make them.
Explanation: The main difference between current and charge: Current: It is the rate of flow of charge (generally electrons). Current (I) is the physical quantity measured in amperes (A). Charge: It is the deficiency or excess of electrons on a body surface.
Answer: The vapor pressure of the solution is 55.2 torr
Explanation:
and
where, x = mole fraction in solution
= pressure in the pure state
According to Dalton's law, the total pressure is the sum of individual pressures.
x = mole fraction =
Given : 299 g of toluene and 391 g of benzene.
moles of toluene =
moles of benzene=
Total moles = moles of solute (toluene) + moles of solvent (benzene) = 3.25 + 5.01 = 8.26
= mole fraction of benzene =
=mole fraction of toluene = (1-0.39) = 0.61
Thus the vapor pressure of the solution is 55.5 torr
Answer:
what is a system at equilibrium?
I think the answer is through the interaction of free and self-directed market forces
