Answer:
Most solids in solution exhibit a general trend of increasing solubility with increasing temperature.
A seed crystal may be added to a supersaturated solution to precipitate excess solute.
Explanation:
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions(Lumen Learning).
When a seed crystal is added to a supersaturated solution, excess solute begin to precipitate because the seed crystal now furnishes the required nucleation site where the excess dissolved crystals now begin to grow.
Answer:
Sodium
(Na)
Just count the electrons and search which atom it is.
Hello there! A proton has a positive charge of (+1) and has a lesser mass compared to a neutron! Hope this helps! Have a great day!
<u>Answer:</u> The volume of concentrated solution required is 42 mL
<u>Explanation:</u>
To calculate the molarity of the diluted solution, we use the equation:
where,
are the molarity and volume of the concentrated solution
are the molarity and volume of diluted solution
We are given:
Putting values in above equation, we get:
Hence, the volume of concentrated solution required is 42 mL
