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>

Decay of Uranium-238 produces gamma radiaton whereas decay of thorium-234 releases beta radiation.
<h3>What type of radiation is produced?</h3>
In the decay of U-238, two gamma rays of different energies are emitted in addition to the alpha particle while on the other hand, in the decay of thorium-234 , beta rays are emitted.
So we can conclude that decay of Uranium-238 produces gamma radiaton whereas decay of thorium-234 releases beta radiation.

Answer:CH3COOH + NaHCO3 > H2O + CO2(g) + CH3COONa
Explanation:acid and base neutralize creating water and CO2 gas along with a salt
The tea was no longer hot or (brewed) so the 5th didn’t dissolve like the others because the tea was hot or warm enough anymore it cooled down. So the sugar won’t dissolve no more.
