Answer:
Weak bonds require less energy to form than strong bonds
Explanation:
According to Coulomb's law, the force between two species is inversely proportional to the distance between them. That said, the bigger the atoms are, the greater the bond length should be to form a molecule.
As a result, for a greater bond length, the attraction force is lower than for a shorter bond length. This implies that large atoms would form weak bonds and small atoms would form strong bonds.
Bond energy is defined as the amount of energy required to break the bond. If a bond is weak, it would require a low amount of energy to break it. This is also true for energy of formation, as it's the same process taking place in the opposite direction.
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

NaOH (s) is in solid state and NaOH (aq) is an aqueous solution.
Can vary. Carbon is used quite commonly, and extracts metal oxides, works with zinc, iron, tin, lead and copper.
