B directly; inversely
Pressure and volume have an inverse relationship (when one increases the other increases) while volume and temperature are direct (if one increases so does the other)
Note: these relationships are only true if other factors are constant such as the temperature, and amount (in moles).
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>
Answer:
You will be watching for 6 hours
Explanation:
We will have 45 x 8 which will give us 360 then we divide it by 60 which will give us 6.
You could solve it by analyzing the points by graphing them on a coordinate plane
