Balanced chemical reaction:
PbO₂<span>(s) + Sn(s)+ 4H</span>⁺(aq) → Pb²⁺(aq) + Sn²⁺(aq) + 2H₂O<span>(l).
Oxidation half-reaction: Sn </span>→ Sn²⁺ + 2e⁻.<span>
Reduction half-reaction: PbO</span>₂ + 4H⁺ + 2e⁻ → Pb²⁺ + 2H₂O.
Net reaction: Sn + PbO₂ + 4H⁺ + 2e⁻ → Sn²⁺ + 2e⁻ + Pb²⁺ + 2H₂O.
Oxidation is increase of oxidation number, reduction is decrease of oxidation number.
Answer:
Direct relationship
Explanation:
I took the test. Good luck!
Stored in bonds of chemical compounds is the right answer
Answer:

Explanation:
Hello,
In this case, we employ the combined ideal gas law in order to understand the volume-gas-pressure behavior as shown below:

Hence, solving for the final pressure P2, we obtain (do not forget temperature must be absolute):
