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:
Option (A) : Positive
Explanation:
A combustion reaction will always be associated with a change in entropy that is Positive due to the gaseous products released. Hence, there is a large positive entropy change.
No.
Electromagnetic waves can travel without a medium.
hope this helps and have a great day :)
North Carolina winter weather evolves from complex meteorological patterns that are difficult to forecast, and which lead to considerable variability in weather conditions across the state. As a result, the frequency and intensity of winter weather events are highly variable and dependent upon large (synoptic) and small (mesoscale) scale atmospheric patterns.
The jet stream is a narrow band of strong winds in the upper atmosphere. In winter, it separates cold, Arctic air masses from warmer, continental air masses. Certain regions of the jet are also favorable for storm development, while others are not.<span>The orientation and location of the jet stream has large implications on the weather year-round, but even more so in winter because the jet stream is stronger due to a large temperature contrast from the north to south.
i know nothing about science but then it just comes to me and i get it right.
