The amount of solute that will crystallize out of the supersaturated solution when it returns to being a saturated solution at 0°C is 46 g
<h3>Saturated and Supersaturated Solution</h3>
- A saturated solution is a solution that contains as much solute as it can dissolve at that temperature in the presence of undissolved solute particles
- A supersaturated solution is a solution which contains more solute than it can normally hold at that temperature.
A supersaturated solution is unstable and the excess solute will separate out of the solution if disturbed slightly or a tiny solute crystal is added to it.
<h3>Solubility curves</h3>
- A solubility curve is a graph or curve of solubility of a substance against temperature.
It is a curve that shows the effect of temperature on solubility of of a substance.
From the solubility data provided, the amount of solute that will crystallize out of solution can be determined:
- Solubility of AgNO3 at 60°C = 106 g/100g H2O
- Solubility of AgNO3 at 0°C is 60 g/100 g H20
When the solution was cooled to form a supersaturated solution, the solution contains 106g of AgNO3
When the solution returns to being a saturated solution at 0°C:
Amount of solute that crystallizes out = 106g - 60 g
Amount of solute that crystallizes out = 46 g
Therefore, the amount of solute that will crystallize out of the supersaturated solution when it returns to being a saturated solution at 0°C is 46 g

Answer:directly to the right
Explanation:
Atomic size increases from left to right
Answer:
Option a.
Explanation:
The transformation of a solid into liquid is a slow process, hence a rate of heating too fast, near the melting point of the sample, will not give the right time to the crystals of the sample to absorb the heat and to melt in the outside and the inside, leading to wrong results in all cases. If we heat to fast, the melting point range will be too broad and will be misleading, resulting in values of the range more hight than the theoric ones.
A rate of 1 °C/min or 2 °C/min is the most appropriate to approach the melting point of the sample. Since it is too slow, from preventing the experiment taking forever it is recommended to start the experiment at a high heating rate until it reaches 20 °C below the melting point, and then, turn the heating rate down to 1 °C/min or 2 °C/min.
Therefore, the correct answer is a: near the melting point of the sample, we must heat slowly until it reach the expected temperature.
I hope it helps you!
I believe that it is Ionic because it conducts electricity when dissolving in water
