Answer:
1.20 V
Explanation:
The standard cell potential is calculated from the expression
ε⁰ cell = ε⁰ oxidation + ε⁰ reduction
The species that will be reduced is the one with the higher standard reduction potential and the species that will be oxidized will be the one with the more negative reduction potential.
Thus for our question we will have
oxidation:
Pb(s) → Pb2+(aq) + 2 e- ε⁰ oxidation = - ε⁰ reduction
= - ( - 0.13 V ) = + 0.13 V
reduction
Br2(l) + 2 e- → 2 Br-(aq) ε⁰ reduction = +1.07 V
ε⁰ cell = ε⁰ oxidation + ε⁰ reduction = + 0.13 V + 1.07 V = 1.20 V
<span>A polymer forms because the hydrocarbon joins with itself in a polymerization reaction.
I really hope this helps! :D</span>
The absorted energy makes molecules in air move and expand therefore decreasing the airs density..
It’ll cause an explosion because it contains lots of different chemicals & all of the chemicals mixed with fire would set off an explosion.
