Answer:
There are 7.5 moles of salt
Explanation:
5.0M means that in every liter of solution, there are 5 moles of salt. So, 1.5L of solution times 5 moles per liter equals 7.5 moles
Answer:

Explanation:
The pH of a solution can be found by using the formula
![pH = - log [ {H}^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20%7BH%7D%5E%7B%2B%7D%20%5D)
Since we are finding the H+ ions we find the antilog of the pH
So we have

We have the final answer as

Distance of something it can be any type of distance
Answer:
The balance between intermolecular forces and kinetic energy
Explanation:
If the kinetic energies of the particles are not strong enough to overcome the intermolecular forces, the particles will be locked in place in a crystal lattice. The substance will be a solid.
If the kinetic energies of the particles are slightly stronger than the intermolecular forces, the particles will be able to slide past each other. The substance will be a liquid.
If the kinetic energies of the particles are much stronger than the intermolecular forces, the particles will be escape completely from the attractions of their neighbours. The substance will be a gas.
