Answer: They are close to each other by 41.03 m^3
Explanation:
From Ideal gas equation, PV = nRT
Where n is negligible
R is gas constant = 8.314 J/mol.k
T = 30 + 273 = 303K
P = 1.02 * 103351.5 = 103351.5 Pascal
Then;
PV = RT
V = P/RT
V = 103351.5/(8.314*303)
V = 41.03m^3
Zn + Cu²⁺ → Zn²⁺ + Cu
Explanation:
The overall equation of this redox reaction is combination of the two half equations. The similar species on both sides are cancelled out leaving a net overall reaction:
Zn → Zn²⁺ + 2e⁻ oxidation step
Cu²⁺ + 2e⁻ → Cu reduction step
Combining both equations:
Zn + Cu²⁺ + 2e⁻ → Zn²⁺ + 2e⁻ + Cu
since the common specie on both sides is 2e⁻, they cancel out to give an overall reaction:
Zn + Cu²⁺ → Zn²⁺ + Cu

Answer:
Yes, you can detect the difference visually.
Since protons are postive and neutrons are neutral. Then it is postive.
A is the answer because the others don't make sense. B if you put glass over reactants it doesn't change anything in the reaction. C using a solid with a low surface area will actually be doing the opposite, a higher SA will increase the rate of reaction. D decreasing the concentration will decrease the reaction
