Below are two chemical equations:
Zn (s) + CuSO (aq) → ZnSO (aq) + Cu (s)
Pb (s) + CuCl (aq) → PbCl (aq) + Cu (s)
Why does copper get separated from its compound form in both the cases?
Choose the CORRECT option.
(i) The volume of air that will remain in the lungs after a normal expiration is called residual volume.
(ii) Volume of air inspired or expired during a normal respiration is called, tidal volume.
(iii) The maximum volume of air a person can breathe in after a forced expiration is called vital capacity.
