Answer:
unsaturated solution
Explanation:
This solution is made by the coffee, which is the solvent and the sugar, which is the solute. The solute dissolves in the solvent.
Sugar starts to precipitate because it cannot dissolve anymore. This means that the solution at the equilibrium point and is saturated. Since more coffee or solvent is added, the solution will now be able to dissolve more sugar. This means that the solution is unsaturated
Answer: - 0.75
Explanation:
For this question, you must remember that a fraction can be written of division.
So, -3/4 = -0.75, between -0.7 and -0.8 on the number line.
Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.
According to the balanced reaction equation:
2KClO3→ 2KCl + 3O2
from this equation, we can see that the molar ratio between KCl & O2 is 2 : 3
so, 2 moles of KCl will need 3 moles of O2
∴ 7.16 moles of KCl will need X moles of O2
∴number of moles of O produced = 7.16 * 3 / 2
= 10.74 moles
