When a lead storage battery is discharged:

(a)    SO2 is evolved

(b)   Lead sulphate is produced at both electrodes

(c)    Sulphuric acid is consumed

(d)    Water is formed

6 years ago


Answers : (1)




in a lead storage battery ,there are two types of reactions: charging &discharging

discharging means battery in use

anode:solid lead rod

cathode:lead dioxide

at anode lead sulphate is deposited

at cathode lead sulphate &water is produced

so (b)  is most appropriate.

sulphuric acid gets consumed with time.

The molar volumes of ice and water are 0.0196 and 0.0190 litres per mole at 273K. If ΔHefor the transition of ice to water is 1440 calories per mole at 1 atm pressure, find ΔU.
Since heat is absorbed here at constant pressure so ΔH = 1440 calories ΔU can be calculated by using the formula : ΔU=ΔH-PΔV P= 1atm, ΔV = 0.0196L - 0.180L = 0.0016 L PΔV = 1*0.0016=...
