We have the compound: KSCN, Potassium thiocyanate, in an aqueous solution.
The dissociated reaction of the salt:
KSCN (aq) => K+ + SCN-
It has 2 ions. One of them is the potassium ion, K+ (cation) and the other one is the thiocyanate ion, SCN- (anion).
Answer:
K+, the potassium ion
SCN-, the thiocyanate ion
Answer:
B. two rounds of cell division
