How could you “supersaturate” solutions, exceeding the amount of dissolved solute possible
Bingel [31]

Answer:

Explanation:

In a saturated solution, more solute cannot be dissolved at a given temperature.

This is because, the solute dissolves in a solvent because of space between particles of solvent but on continuous addition of solute, the space between the solvent particles gets fulfilled. Thus no more solute particle can dissolve in a solvent.

A sample of aluminum absorbs 9.86 J of heat, upon which the temperature increases from 23.2°C to 30.5°C. Since the specific heat
True [87]

Answer:

1.50 g

Explanation:

The heat absorbed by the aluminum in this case is:

q = m x C x ΔT     m= q/ (C x ΔT)

q= 9.86 J

C = 0.90 J/g-K

ΔT = ( 30.5 ºC - 23.2 ºC ) = 7.3 ºC = 7.3 K (this is a range of temperature)

m = 9.86 J / ( 0.90 J/g-K ) x 7.3 K ) = 1.50 g

A solution of KCIO3 is prepared using 75 grams of the solute in enough water to make 0.250 liters of solution. The gram-formula
charle [14.2K]
Using the mass/volume percentage method for percentages of the solution, you simply divide the grams of solute by the volume of the solution and multiply by 100 to get your percentage.
(75.0g/250mL)•100 = 30.0% solute
