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:
it would be in the keyhole probably
Explanation:
Because you would have to put the screwdriver inside to try and break the lock
Answer:
The correct answer would be the use of differential and selective growth medium.
Explanation:
The mixed colonies states of certain species can be developed on the differential and specific media relying on the morphology saw in the general media. These types of selective and differential media will allow certain microorganisms to grow only and not all the rest species present on the media.
It will help in recognizing species present in the mixed colonies present in such a growth medium. Different tests like catalase can be performed to dispose of certain choices not long before the utilization of the differential and particular media.
Thus, the correct answer would be the use of differential and selective growth medium.
No, there is not more water. It just appears this way because the new glass is smaller and the water takes up more room in it than it did in the larger glass.
