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:
bines relative humidity and temperature in a comfort index
Explanation:
The Heat Index temperature measures how hot it feels when humidity is factored with the air temperature.
It is important for the human body's comfort.
The human body feels warmer in humid conditions it begins to perspire or sweat to cool itself off when the body gets too hot.
The concept of the heat index was developed by George Winterling in 1978.
The heat index temperature makes assumptions regarding the human body mass and height, clothing, amount of physical activity etc.
The heat index temperature <u>bines relative humidity and temperature in a comfort index.</u>
