The difference between the electrode potentials of two electrodes when no current is drawn through the cell is called _____.(Cell emf/Cell potential)

The reaction is spontaneous if the cell potential is _____.(Positive/Negative)

EMF of a cell in terms of reduction pontential of its left and right electrodes is:

The reaction is spontaneous if the cell potential is

The IUPAC name of the gas released in the above diagram, where a blank is given is :

(Note : Fill the blanks by writing the chemical formulas in straightforward manner without using subscript. For example, the chemical formula of methane should be filled in the blank as $\mathrm{CH}4$ and not as ${\mathrm{CH}}_4$)

A reference electrode refers to an electrode that has a variable electrode potential.

The following reaction occurs in a galvanic cell $2{\mathrm{Cu}}^{+}⟶{\mathrm{Cu}}^{2+}+\mathrm{Cu}$. If ${\mathrm{E}}_{{\mathrm{Cu}}^{+}/{\mathrm{Cu}}^{2+}}^0=+0.16 \mathrm{V}$ and ${\mathrm{E}}_{{\mathrm{Cu}}^{+}/\mathrm{Cu}}^0=0.52 \mathrm{V},$ the standard cell potential will be
