KClO3 (aq) will have greater molar entropy than KClO3 (s) because molar entropy increases with increase in temperature.
As the temperature rises, the standard molar entropy of any substance rises. Entropy and a Single Substance's Temperature ” Entropy increases significantly when a solid turns into a liquid and when a liquid turns into a gas. The entropy of the liquid is lower than that of the gas. As a result, entropy rises in reactions that produce gaseous byproducts from solid or liquid reactants. When solid reactants produce liquid products, entropy also rises.

The water becomes a vapor. there are 2 ways condensation happens: either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
Answer:
A. The number of moles of HNO2 will remain the same. True
B. The number of moles of NO2- will remain the same. False
C. The equilibrium concentration of H3O will remain the same. False
D. The pH will decrease. False
E. The ratio of [HNO2] / [NO2-] will remain the same. True
Explanation:
The mixture of nitrous acid and potassium nitrite is a buffer solution. Hence the properties outlined above. Buffer solutions are designed to militate against changes in acidity or alkalinity. This explains why the above statements were categorized as true or false accordingly.
Molar mass ( CuSO₄) = 159.609 g/mol
159.609 g ----------------- 6.02 x 10²³ molecules
? g ------------------ 3.36 x 10²³ molecules
mass = ( 3.36 x10²³) x 159.609 / 6.02 x 10²³
mass = 5.36 x 10²⁴ / 6.02 x 10²³
mass = 8.90 g
hope this helps!
