Answer:
4909.486Kj/mol
Explanation:
the heat would be required to change steam at 100°c to water at 100°c then change the water at that temperature to water at 0°c then change water at 0°c to ice at 0°c then ice at 0°c to ice at -15°c
Answer :
(A) The number of moles of ions per liter is, 0.1 moles/L
(B) The number of molecules of ion is,
(C) The pH of the solution will be, 4
<u>Solution for part A :</u>
First we have to calculate the pOH of the solution.
As we know that,
Now we have to calculate the moles of ion per liter.
<u>Solution for part B :</u>
First we have to calculate the ion concentration.
Now we have to calculate the number of molecules of ion
As, 1 mole contains number of molecules of ion
So, moles contains number of molecules of ion
<u>Solution for part C :</u>
Answer:
Explanation:
Hello!
In this case, since the writing of a net ionic equation first implies writing the complete molecular equation:
We can see that HCl and MgCl2 are ionized because they are aqueous, thus we write:
In such a way, we can cancel out the chloride ions as they are the spectator ones to obtain the net ionic one:
Best regards!
The property of a solution which remain the same after it is diluted is THE AMOUNT OF SOLUTE.
Dilution is the process of adding solvent to a solution. This action decreases the concentration of the solute in the solution. When a solution is diluted, the amount of solvent increase, the total volume increases, the concentration decreases, but the amount of solute stays the same.
