Use bond energies to calculate ΔHrxn Δ H r x n for the reaction. 2H2(g)+O2(g)→2H2O(g) 2 H 2 ( g ) + O 2 ( g ) → 2 H 2 O ( g

Description: You determine the power needed to break all bonds inside reactants.
You then subtract the power had a need to break all bonds inside items.
                      2H₂   +   O₂ ⟶ 2H-O-H
Bonds:          2H-H    1O=O       4H-O
D/kJ·mol⁻¹:     436      498          464

it can take on an electronical power

Ametal with most free-flowing electrons likely features great conductivity
