Options
- A(i) ( ) Q, (ii) ( R ), (iii) ( P ), (iv) ( S )
- B(i) ( R ), (ii) ( Q ), (iii) ( P ), (iv) ( S )
- C(i) ( Q ), (ii) ( R ), (iii) ( S ), (iv) ( P )
- D(i) ( ) Q, (ii) ( ) S, (iii) ( ) P, (iv) ( R )
Correct answer
A. (i) ( ) Q, (ii) ( R ), (iii) ( P ), (iv) ( S )
Step-by-step solution
(i) During discharging of lead storage battery: The concentration of ( H ₂ SO ₄ ) (sulfuric acid) decreases as it reacts with the lead plates. Match: Q) Conc. Of ( H ₂ SO ₄ ) decreases (ii) Energy of combustion is converted into electrical energy: This describes a fuel cell, which converts chemical energy from combustion into electrical energy. Match: R) Fuel cell (iii) Leclanche cell: A Leclanche cell consists of a zinc container as the anode. Match: P) Cell consists of zinc container as anode (iv) Mercury cell: T
