Unlike nuclear reactions, nuclear reactions are not affected by changes in temperature,
pressure, of the presence of catalysts. Also nuclear reactions of given radioisotope cannot be slowed down, speeded up, or stopped.
L

mol/dm³ is measure for molarity
Answer:
D because excited electrons fall back.....
For the equation to be balanced, the Atom's coefficient on the left side and the right side of the equation has to be equal
so, the answer would be :
Br2 + S2032- + 5H20 -- > BR2- + 2S02- + H+
Hope this helps
