Aside from silica gel and alumina what other stationary phase can you use in chromatography​

Chemistry
1 answer:
Svetlanka [38]3 years ago
7 0

Answer:

Paper

Explanation:

In chromatographic separation, two different phases are important; a stationary phase and a mobile phase.

The stationary phase is the phase that does not move. Substances are separated based on how fast or slowly they move in the stationary phase.

The mobile phase is usually the solvent(or mixture of solvents) that carries the solutes through the stationary phase.

The stationary phase is usually composed of a porous material. Paper is a porous material. The mobile phase is trapped between the cellulose fibers of the paper and separation is achieved.

How many grams (m) of glucose are in 165 ml of a 5.50% (m/v) glucose solution? express your answer numerically in grams?
Leya [2.2K]
     <span> mass of glucose = 0.055 *165 = 9.075 g

vol of methyl alc = 0.185 * 1.87 = 0.346 L = 346 ml

% NaCl ( m/v ) = mass NaCl * 100/ vol of soln

or Vol of Soln = mass NaCl / % NaCl (m/v)

= 32.1 * 100 / 6 = 535 ml the total vol of soln</span>

The volume of a weather balloon is 200.0 L and its internal pressure is 1.17 atm when it is launched at 20 °C. The balloon rises
brilliants [131]

Answer:

2022 L

Explanation:

Ideal gas laws will work for gas in the balloon

The general gas law is for a gas at two arbitrary states 1 and 2 is given by

(P₁ V₁)/T₁ = (P₂ V₂)/T₂

P₁ = 1.17 atm

V₁ = 200.0 L

T₁ = 20°C = 293.15 K

P₂ = 63 mmHg = 0.0829 atm

V₂ = ?

T₂ = 210 K

(1.17 × 200)/293.15 = (0.0829 × V₂)/210

V₂ = (210 × 1.17 × 200)/(293.15 × 0.0829)

V₂ = 2022 L
