Answer:
Vapor pressure of the solution is 22.9 torr at 25°C
Explanation:
When a non volatile solute is added to a pure solvent, the vapour pressure of the mixture decrease regard to the pure solvent following the equation (Raoult's law):
Where vapour pressure of the pure solvent (Water) is 23.8torr at 25°C.
Mole fraction of water is the ratio between moles of water and total moles in solution. The solution has a mole fraction of water of:
Replacing in Raoult's law:
<h3>Vapor pressure of the solution is 22.9 torr at 25°C</h3>
Answer:
the heat required to raise the temperature of the unit mass of a given substance by a given amount
Explanation:
The stable form of Nitrogen is N-14 and N-15.
- Nearly all proteins contain nitrogen, which is crucial for biochemical processes as well as industrial processes.
- Due to its capacity to form a triple bond with both itself and other elements, nitrogen forms strong bonds. As a result, nitrogen compounds contain a lot of energy. Little was known about nitrogen before one hundred years ago.
- More than 99 percent of all nitrogen found on Earth is found in the most abundant form of nitrogen, nitrogen-14. non-radioactive and stable, it is a substance.
- The most widely used form of nitrogen, 14, is used in biochemicals, biomedical research, food preservation, and agricultural practices.
- The second stable state of nitrogen is nitrogen-15. It is frequently employed in medical preservation and research.

I’m not sure...
A to B : the motion is increasing so the velocity is increasing as well and you can calculate it with the slope.
B to C : the motion is constant. So the velocity is 0
C to D : the motion is decreasing so the velocity is decreasing as well.
Hope you will understand bc English is not my first language....
It;s a physical change because the tablet dissolved and it made the water cooler
