Explanation:
In a voltaic cell, oxidation reaction occurs at anode whereas reduction reaction occurs at the cathode.
Hence, the half-cell reaction taking place at anode and cathode will be as follows.
At anode (Oxidation) : ...... (1)
At cathode (Reduction) :
So, in order to balance the half cell reactions, we multiply reduction reaction by 3. Hence, reduction reaction equation will be as follows.
........ (2)
Therefore, overall reaction will be sum of equations as (1) + (2). Thus, net reaction equation is as follows.
Answer:
In fact, the periodic table is so accurate that it allows scientists to predict the chemical and physical properties of elements that hadn't yet been discovered. ... "The elements, if arranged according to their atomic weights, exhibit an apparent periodicity of properties," said Mendeleev.
