The answer is Sodium Sulfite
Hope it helps
The Correct choice is A. H+ , F- and HF
Since HF is a weak acid, it behaves like an weak electrolyte in water. so, there is incomplete dissociation of HF in water. Therefore, there will be HF molecules present in the solution along with the ions ~
The mass of the atom would change. With no atoms being there then the mass would possibly change. With no neutrons then the mass of the atom will decrease
We can write the balanced equation for the galvanic cell by using the oxidation and reduction half-reactions. In the anode, Ni(s) is oxidized and produces aqueous Ni2+:
Ni(s) → Ni2+
while in the cathode, Cu2+ is reduced and deposits copper:
Cu2+ → Cu(s)
We now balance the charge of each reaction by adding electrons to the side of the equation with the greater charge:
Ni(s) → Ni2+ + 2 e-
Cu2+ + 2 e- → Cu(s)
Finally, we add the half-reactions to obtain the overall balanced equation for the galvanic cell:
Cu2+(aq) + Ni(s) → Ni2+(aq) + Cu(s)
Answer:
Neutral. There are equal amounts of protons or positively charged parts and electrons or negatively charged parts. The neutrons have no net charge which means this atom of chlorine is neutral.
