<u>Answer:</u> The wavelength of an electron is 
<u>Explanation:</u>
To calculate the wavelength of a particle, we use the equation given by De-Broglie's wavelength, which is:
where,
= De-Broglie's wavelength = ?
h = Planck's constant = 
m = mass of electron = 
v = velocity of electron = 
Putting values in above equation, we get:
Hence, the wavelength of an electron is
A picture of the electroplating apparatus can be found attached. The nail (cathode) is completely submerged and that is where reduction happens. In the other side, the copper strip is (anode) where oxidation happens. The electron flow happens from the anode to the cathode. The positive charge of the battery is attached to the anode while the negative side is attached to the cathode.
The question is incomplete; the complete question is;
Why will the conjugate base of a weak acid affect pH? Select the correct answer below: O it will react with hydroxide
O it will react with water
O it will react with hydronium
O none of the above Content attribution
Answer:
O it will react with hydronium
Explanation:
If we have a weak acid HA, the weak acid ionizes as follows;
HA(aq) ----> H^+(aq) + A^-(aq)
A^- is the conjugate base of the weak acid.
H^+ interacts with water to form the hydronium ion as follows;
H^+(aq) + H2O(l) ----> H3O^+(aq)
The pH=[H3O^+]
But the conjugate base of the weak acid reacts with this hydronium ion thereby affecting its concentration and the pH of the system as follows;
A^-(aq) + H3O^+(aq) ------> HA(aq) + H2O(l)
