They always show evolutionary relationships of organisms.
The answer is true that’s the right answer
Given the reaction equation; ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l), the cell notation is Cu/Cu2+//ClO3-/Cl/Pt.
<h3>What is an electrochemical cell?</h3>
A electrochemical cell is one in which electrical energy is produced by chemical processess. In this case, the cell reaction equation is; ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l).The electrode used here is Pt.
Looking at the equation, we can write the notation for the cell reaction as;Cu/Cu2+//ClO3-/Cl/Pt.
