Answer:
B. The reactants form additional unexpected products.
Explanation:
Answer: Oxidation half: 
Reduction half: 
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
Oxidation half:
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.
Reduction half:
Answer:
A. 0.0005u
Explanation:
The mass of an electron in amu = 9.1*10-311.66*10-27=0.0005u.
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
