Answer: The final pressure is 0.81 kPa
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 0.58 kPa
= final pressure of gas = ?
= initial volume of gas = v
= final volume of gas =
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The final pressure is 0.81 kPa
Answer:
A, Hail is large spheres of ice and snow is small flakes of ice.
Answer:
I think it is B. takes place slowly. hope this helps!
Yeah 45 I think because the container is closed
Strong solute-solvent attractions increase solubility of ionic compounds. Ionic compounds are most soluble in polar solvents like water, because the ions of the solid are strongly attracted to the polar solvent molecules.
COMMON-ION EFFECT
Ionic compounds are less soluble is solvents that contain a common ion. For example, CaSO₄ is slightly soluble in water.
CaSO₄(s) ⇌ Ca²⁺(aq) + SO₄²⁻(aq)
If the water already contains calcium ions or sulfate ions, the position of equilibrium moves to the left and the solubility decreases (Le Châtelier’s Principle).
TEMPERATURE
Increasing the temperature usually increases the solubility of an ionic compound because the solution process is usually endothermic.
CaSO₄(s) + heat ⇌ Ca²⁺(aq) + SO₄²⁻(aq)
Le Châtelier’s Principle predicts that increasing the temperature (adding heat) will shift the position of equilibrium to the right. The compound will become more soluble. From a webpage i found this from https://socratic.org/questions/what-factors-affect-solubility-of-ionic-compounds
