The lead acid battery produces energy by oxidation of lead. The amount of lead oxidized in this case is 1.47 g.
<h3>What is lead acid battery?</h3>
The lead acid battery is the common accumulator that we have in use. It is made up of a cell that contains lead electrodes in an acid.
The oxidation of lead occurs according to thr equation;
Pb(s) ----> Pb^2+(aq) + 2e
If 207 g of Pb is oxidized by 2(96500)C
x g of lead is oxidized by (221 * 6.20) C
x = 207 g * (221 * 6.20) C/2(96500)C
x = 1.47 g

Sodium hydroxide and hydrochloric acid can react with each other to form sodium chloride in the reaction HCl(aq)+NaOH(aq)→H₂O(l)+NaCl(aq).
I hope this helps. Let me know if anything is unclear.
First, we convert the given amount of energy into joules.
1 kJ = 1000 joules
2.2125 kJ = 2,212.5 Joules
Each kilocalorie contains 4,184 Joules
Kilocalories = 2,212.5 / 4,182
Kilocalories = 0.529
1 kilocalorie = 1000 calories
0.529 kilocalories = 529 calories
Lets take one element from Group 6A, Let it be oxygen, The electronic configuration of Oxygen is as follow,
O = 8 = 1s², 2s², 2px², 2py¹, 2px¹
There are 6 electrons in the valence shell of elements present in Group 6A. The unpaired electrons in 2px and 2py are involved in forming covalent bond, while the pair of electrons in 2s and 2px are unshared and act as lone pair of electrons.
Result:
There are TWO unpaired electrons present in the ground state of Group 6A elements.
