Answer:
A
Explanation:
In a galvanic cell, energy is produced by spontaneous chemical processes.
The cathode and anode of this cell will depend on the relative position of the two metals in the electrochemical series.
Aluminium is higher in the electrochemical series so aluminium will be the anode. Silver is lower in the electrochemical series so silver will be the cathode.
Recall that oxidation (electron loss) occurs at the anode while reduction (electron gain) occurs at the cathode.
Answer:
b
Explanation:
because it is products /reactants :)
For cations, the loss of an electron leaves them with a net positive charge, whereas for anions, the addition of an electron leaves them with a net negative charge. Understanding the processes behind this, including the ionization energy and electron affinity of different atoms, helps you see why certain atoms become ions more easily than others and what causes it to happen.
