Answer:
Q1: 1.67 L.
Q2: Saturated solution.
Explanation:
<u><em>Q1:</em></u>
- We have the role that the no. of millimoles before dilution is equal to the no. of millimoles after dilution.
<em>(MV) before dilution = (MV) after dilution</em>
M before dilution = 10.0 M, V before dilution = 0.5 L.
M after dilution = 3.0 M, V after dilution = ??? L.
<em>∴ V after dilution = (MV) before dilution / M after dilution</em> = (10.0 M)(0.5 L) / (3.0 M) =<em> 1.67 L.</em>

<u><em>Q2:</em></u>
From the given curve, it is clear that the solubility of sodium nitrate at 35.0°C is 100 g per 100 g of water.
<em>So, the mentioned solution is a saturated solution at this T.</em>
<em></em>
<em>A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent.</em>

The water cycle does not ensure that we have water. We must HAVE water to cause water cycle.
Evaporation, then condensation, and finally precipitation.
This would happen in order.

Selectively Permeable means that some things can move across the cell membrane while others cannot.
Here is a sentence: Because of the selectively permeable membrane, the germs were kept out while the food went in.
