Answer:
A: The first one because it is going upward and that means getting warmer.
B: The second one is the cooling curve because it is going downward and that means cooler.

I hope this helps.
Answer:
XL(toluene) = 0.77
XL(benzene) = 0.23
Explanation: see attachment
Answer is: solution B is saturated and solution A is unsaturated.
Saturated solution contains the maximum concentration of a solute dissolved in the solvent (usually water) and if extra solute is added to saturated solution, that solute will not dissolve.
Unsaturated solution means that more of a substance can be dissolved (in this example salt).
The answer for your question is B!
Answer:
Supersaturated.
Explanation:
Hello there!
In this case, according to this solubility chart, we infer that for NH3, the solubility starts at 90 grams of NH3 that are soluble in 100 g of water at 0 °C and ends in about 8 g in 100 g of water at 100 °C for a saturated solution.
However, since we are asked for the solubility of NH3 at 20 °C, we can see that, according to the table and the curve for NH3, about 52 g of NH3 are soluble in 100 g of water; thus, for the given 60 g of NH3, we will say that 8 grams will remain undissolved, and therefore, this solution will be supersaturated.
