Answer:
Copper metal can exist as <em><u>Cu+</u></em><em><u> </u></em><em><u>and </u></em><em><u>Cu2+</u></em><em><u> </u></em>
ions.
The equilibrium constant of the reaction is 1.21 * 10^6 while the change in free energy is -34.7 kJ.
<h3>What is equilirium constant?</h3>
The equilibrium constant shows the extent of conversion of reactants to products.
Now we know from the Nernst equation that;
Ecell = E°cell - 0.0592/n logQ
E°cell = 0.52−0.16=0.36 V
Since Ecell = 0 V at equilibrium,
0 = 0.36 - 0.0592/1 log K
0.36 = 0.0592/1 log K
log K = 0.36/ 0.0592
K = antiog (0.36/ 0.0592)
K = 1.21 * 10^6
ΔG = -RT lnK
ΔG =-(8.314 * 298 * ln1.21 * 10^6)
ΔG =-34.7 kJ

Answer: A chlorine atom has an atomic number of 17 and a mass number of 38. This chlorine atom has 18 neutrons
Hope this helps :)
2.4 x 10²² atoms
<h3>Further explanation</h3>
Atomic mass is the average atomic mass of all its isotopes
In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu
So the atomic mass obtained is the mass of the atom relative to the 12th carbon atom
mass single Uranium atom=4.7 x 10⁻²² g
then for 111 mg=0.111 g
