Answer:
Composition of the mixture:
%
%
Composition of the vapor mixture:
%
%
Explanation:
If the ideal solution model is assumed, and the vapor phase is modeled as an ideal gas, the vapor pressure of a binary mixture with 
and 
molar fractions can be calculated as:
Where 
and 
are the vapor pressures of the pure compounds. A substance boils when its vapor pressure is equal to the pressure under it is; so it boils when 
. When the pressure is 0.60 atm, the vapor pressure has to be the same if the mixture is boiling, so:
With the same assumptions, the vapor mixture may obey to the equation:
, where P is the total pressure and y is the fraction in the vapor phase, so:
%
The fractions of B can be calculated according to the fact that the sum of the molar fractions is equal to 1.
Answer:
B) A drawn bow is released, causing an arrow to fly across the field
Explanation:
Potential energy can be thought of as "potential" to do something. For eg, putting a ball on top of hill causes the ball to have the potential to roll down the hill if released. Here the ball converts the potential energy into kinetic energy (energy of motion) to roll down.
Similarly, the bow has been stretched (potential to fly if released), and when its released, it converts the potential energy into kinetic energy.

Answer:
Carbon dioxide
Explanation:
<em> laboratory to have a pH of less than 7.0.</em>
Carbon (IV) oxide in the atmosphere is capable of dissolving into the distilled water to form a weak acid. Any pH that is less than 7.0 is acidic while any pH above 7.0 is alkaline or basic.
First, the carbon (IV) oxide enters the water through an equilibrium with the atmosphere:
Thereafter, aqueous carbon (IV) oxide can then react with water to form a weak carbonic acid:
