By increasing temperature, molecules of the solution no longer forms aggregates and solution becomes unsaturated.

Answer is: by increasing the temperature of the solvent.

Saturated solution contains the maximum concentration of a solute dissolved in the solvent (usually water) and if extra solute is add to saturated solution, that solute will not dissolve.

The amount of solute that can be dissolved in a solvent depends of chemical composition, temperature and pressure.

In this example, because chemical compostion and pressure are the same, the amount of solute that can be dissolved in a solvent depends on temperature.

The higher the temperature of the solvent, the more solute will be dissolved.

Which answer choice best describes the difference between folded mountains and fault-block mountains?
melamori03 [73]

The answer is; C

In folding, when segments of Earth's crust are bent and doubled over, the sediments in between are form folds, since they are forced into a smaller space.  This also occurs in converging plates boundaries.

Block Mountains occur when stress due to compression in the crust causes the hanging wall between a fault to move up relative to the footwall.

A 0.271g sample of an unknown vapor occupies 294ml at 140C and 874mmHg. The emperical formula of the compound is CH2. How many m
Phoenix [80]
Using PV = nRT, we can calculate the moles of the sample.
874 mmHg = 116,524 Pa
n = PV/RT
n = 116,524 x 294 x 10⁻⁶ / 8.314 x (140 + 273)
n = 9.98 x 10⁻³ mol

moles = mass / Mr
Mr = 0.271/9.98 x 10⁻³
Mr = 27.2
Mass of empirical formula = 14
Repeat units = 27.2 / 14 ≈ 2

Formula of substance:
C₂H₄

Combustion equation:
C₂H₄ + 3O₂ → 2CO₂ + 2H₂O

1 mole produces 2 moles of CO₂, so 3 moles will produce 6 moles CO₂

Some atoms are chemically stable and will not bond with atoms of other
tigry1 [53]

Answer:

The stability of atoms depends on whether or not their outer-most shell is filled with electrons. If the outer shell is filled, the atom is stable. Atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability.
