Answer:
The entropy of the final solution decreases, as the reaction disorder is less.
Explanation:
The higher the temperature, the greater the heat of the reaction and the greater the disorder it has, so the entropy will increase ... But this is not the case, since the solution cools, decreasing the entropy proportionally.
We are given with
<span>ΔHo = 38.0 kJ
ΔSo = 112.9
for these standard conditions:
To = 25 C
Po = 1 atm
Using the Clapeyron Equation
ln (P/Po) = (</span><span>ΔHo / R)(1/T1 - 1/T2)
Substitute the values and solve for P (Temperature should be in Kelvin)</span>
Answer:
D. 805 good
Explanation:
Can't really see the table but ionic compounds have high melting points and are good conductors.
When naming an ionic compound, write the name of the cation, which is the metal first. Then, write the name of the anion, which is the nonmetal. However, you remove the last 2-3 letters and replace suffixes.
1. RbF --> Rubidium Fluoride
Change fluorine to fluoride
2. CuO --> Copper (II) Oxide
Change oxygen to oxide. Oxide has a charge of -2. Since no subscripts are written, it means they have the same opposite charge. So, we use Copper (II).

NH₄ is ammonia, but we change it to ammonium for polyatomic ions.
