It would be false adding a solute to a solvent
Answer:
The reaction that occurs is a redox reaction. The Copper metal (Cu 0)on the copper pennies is oxidized in concentrated nitric acid to produce Cu2+ ions. Copper is easily oxidized to Cu2+, which is blue in aqueous solutions (water) so you should see the solution turn blue as the copper penny reacts.
Have a nice day ;)(^-^)
Answer:
No specific heat capacity and heat capacity are not equal
<u>Answer:</u> The molar solubility of MX is 
<u>Explanation:</u>
We are given:

The chemical equation for the ionization of MX follows:

S S
The expression of
for above equation is:
......(1)
The chemical equation for the ionization of
follows:

0.25M 0.5M 0.25M
Total concentration of cation from both the equation is:
![[M^+]=0.5+S](https://tex.z-dn.net/?f=%5BM%5E%2B%5D%3D0.5%2BS)
As,
, so S is also very very less than 1 and can be easily neglected.
So, ![[M^+]=0.5M](https://tex.z-dn.net/?f=%5BM%5E%2B%5D%3D0.5M)
Putting values in equation 1, we get:

Hence, the molar solubility of MX is
