It’s all based on you but yours could be anything hard you went through and how you overcame it. Also say how it made you the person you are today
<span>Dalton's atomic theory originally has 5 postulates. Among the choices, there are three that are included. These are:
*atoms of one element cannot change into atoms of another element.
</span><span>*each element is composed of tiny, indestructible particles called atoms.
</span><span>*atoms combine in simple, whole number ratios to form compounds
The others are incorrect. Atoms of one element cannot change to another element. Atoms of the same element do not have the same mass because they can occur as isotopes. Nuclear particles are not part of Dalton's theory, just the chemical reactions.</span>
Answer:
23.8 torr
Explanation:
Vapor pressure of a liquid is simply the pressure of the vapor that arises when the liquid evaporates in a closed container above the liquid sample.
From the question given above, the vapor pressure is 23.8 torr at 25°C. Since the temperature is constant, the vapor will remain the same when equilibrium is reached in the new container as vapor pressure depends on the temperature of the liquid.
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
