Given :
Volume of NaCl solution 2.5 L .
Molarity of NaCl solution is 0.070 M .
To Find :
How many moles are present in the solution.
Solution :
Let, n be the number of moles.
We know, molarity is given by :

So,

Therefore, number of moles of NaCl is 0.175 moles.
Alpha particles are relatively heave and can be stopped by a sheet of paper.
The type of energy which is present between the repulsion interaction is the highest potential energy.
<h3>What is potential energy?</h3>
Potential energy is the amount of energy that is possess by any body with respect to the electric charge posses in that and other factors also.
- When molecules have a high attraction force then they have the low potential energy in them.
- When molecules have a great repulsion between them then they have the great potential energy in them.
- And molecules have the middle amount of potential energy then they have the balanced interaction.
Hence, molecules in which repulsion interaction is present will have highest potential energy.

<span>1. The two qualities used to describe winds are direction and speed.
2. a local wind that blows during the day from an ocean toward land is a(n) sea breeze.
3. The increase in cooling that wind can cause is called the wind-chill factor.
4. Temperature differences between the equator and poles produce convection currents.
A movement that is parallel to Earth's Surface is called wind and a local wind is that wind that blows over a short distance.</span>
Answer:
Germs stick to the oil on your hands, and washing with just water doesn't work because oil and water don't mix, but soap dislodges the germs and oil from your hands
Explanation:
