The lead-containing reactant(s) consumed during recharging of a lead-acid battery is/are . The lead-containing reactant(s) consumed during recharging of a lead-acid battery is/are . PbSO4 (s) only Pb (s) only PbO2 (s) only both PbO2 (s) and PbSO4 (s) both Pb (s) and PbO2 (s)

 The  lead-containing reactant(s) consumed during recharging of a lead-acid battery is

Explanation:

In lead acid battery, the anode is made up of lead and undergoes oxidation during discharging and cathode is made up of lead oxide and acts as cathode during discharging. The electrolyte used is dilute .

Charging:

Cathode : reduction :

Anode: oxidation :

Overall reaction :

The  lead-containing reactant(s) consumed during recharging of a lead-acid battery is

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
