In order for the molecules to actually separate from each other, more energy must be added. This energy, called heat of fusion or heat of melting, is absorbed by the particles as potential energy as the solid changes to a liquid. I hope this helps
Answer:
hlo please help me to do my question
Answer:
7.81 moles
Explanation:
(4.7×10^24 )×1 moles divided by 6.02×10^23 molecules
Answer:
0.1 liters of NaOH.
Explanation:
When the acid solution is neutralized we have:
Where:
: is the number of moles of the acid
: is the number of moles of the base
: is the concentration of the acid
: is the concentration of the base = 0.1 M
: is the volume of the acid = 10000 L
: is the volume of the base =?
The concentration of the acid can be calculated from the pH:
![pH = -log([H^{+}])](https://tex.z-dn.net/?f=%20pH%20%3D%20-log%28%5BH%5E%7B%2B%7D%5D%29%20)
![[H^{+}] = 10^{-pH} = 10^{-6} M](https://tex.z-dn.net/?f=%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-pH%7D%20%3D%2010%5E%7B-6%7D%20M%20)
Now, we can find the volume of the base:
Therefore, the amount of NaOH needed to neutralize the solution is 0.1 liters.
I hope it helps you!
