Gold is a very nonreactive metal therefore it doesn't rust . Metals lose their shine because they react to other substances .
Hope This Helps You!

The
balanced chemical reaction is 2Hg + O2 -> 2HgO. To calculate the delta G, we
use the formula: ΔG = ΔH – TΔS. The ΔH is computed by subtracting the
standard enthalpy of formation of the reactants from the products, multiplied
correspondingly with their stoichiometric coefficients. The same is to obtain ΔS.
The
necessary information all at 298 K are:
ΔH_Hg
= 0 kJ/mol; since it is at its standard state
ΔS_Hg
= 75.90 kJ/mol
ΔH_O2
= 0 kJ/mol; since it is at its standard state
ΔS_O2
= 0.161 kJ/mol K
ΔH_HgO
= -90 kJ/mol
ΔS_HgO
= 0.070 kJ/mol K
<span>Thus,
the delta G of reaction is -132.022 kJ. The negative value denotes a
spontaneous reaction. </span>
Answer: 400° kelvin
Explanation:
400° k translates to about 260° fahrenheit, and 260 > 100!
