5 moles. The H2O is getting multiplied by a factor 5. So therefore, the CO2 will have to be multiplied by 5 as well. 1x5=5.
The Ka of the solution is 8.1 * 10^-9.
<h3>What is the pH?</h3>
The pH of a solution is the concentration of hydrogen ions in the solution.
Number of moles of the acid = 26.816g/153.483g/mol = 0.175 moles
Concentration of the acid = 0.175 moles/0.5 L = 0.35 M
Now we know that the acid reacts with water as follows;
HA(aq) + H2O(l) ------> H3O^+(aq) + A^-(aq)
[H3O^+] = Antilog (-4.274)
[H3O^+] = 5.32 * 10^-5 M
Since;
[H3O^+] = [A^-] = x
Ka = x^2/[HA]
Ka = (5.32 * 10^-5)^2/( 0.35)
Ka = 8.1 * 10^-9
Hence, the Ka of the solution is 8.1 * 10^-9.

Answer:
Explanation:
The atoms w a positive (+) charge are protons
The atoms with a negative (-) charge are neutrons
The atoms in the outer shells are electrons.
I'm not sure if you just needed to label them or if there's something more but lemme know if so.
Explanation:
1) There are three sub atomic particles; protons, neutrons and electrons. Protons and Neutrons are found in the nucleus while electrons are found in orbitals outside the Nucleus.
2) No. This is not always the case. An example is sodium which has atomic mass of 23.
Atomic Mass = Neutrons + Protons
23 = Neutrons + 11
Neutrons = 23 - 11 = 12
In sodium there are 11 protons and 12 neutrons
