In a chromatography experiment, chlorophyll pigments are separated using paper. What is the stationary phase in this experiment?

2 answers:

4 0

Answer:
The stationary phase in chromatography experiment is paper.

Explanation:
In chromatography experiment, the stationary phase is defined as the fixed substance that is necessary to start chromatography. In our case, this fixed substance is paper, so that makes paper our stationary phase.

Hope this helps :)

Answer:

Chromatography paper.

Explanation:

Chromatography may be defined as the technique used for the separation of molecules on the basis of their size, shape and color. The chromatography requires the mobile phase as well as the stationary phase.

The different pigments of chlorophyll can be separated by the chromatography technique. Here, the chromatography paper work as stationary phase and the drop of cholorophyll is placed on the paper. The water is used as mobile phase and as it moves over the paper separates the component of cholorophyll.

Thus, the answer is chromatography paper.

infrared and raman spectra of magnesium ammonium phosphate hexahydrate ( struvite ) and its isomorphous analogues . i . spectra

kodGreya [7K]

Magnesium potassium phosphate hexahydrate and a number of its deuterated counterparts were studied for their Fourier transform infrared and Raman spectra. By contrasting the spectra obtained at the boiling point of liquid nitrogen with those obtained at ambient temperature and by examining the spectra of a succession of partially deuterated MgKPO4

<h3>What is Infrared and raman spectroscopy ?</h3>

Raman and infrared spectroscopy both investigate how radiation interacts with molecular vibrations, but they do so in different ways depending on how the photon energy is delivered to the molecule by altering its vibrational state.

While IR spectroscopy depends on a change in the dipole moment, Raman spectroscopy depends on a change in the polarizability of a molecule. In contrast to IR spectroscopy, which measures the absolute frequencies at which a sample absorbs light, Raman spectroscopy measures the relative frequencies at which a sample scatters light.

The forces exerted on an object are shown.

marusya05 [52]

Answer:

The object moves up.

Explanation:

I think that's the answer because since F was up that would cause 5 N . To go up.

Tell me if I'm wrong, plz :D

A plasma membrane and a cell wall _____.

klemol [59]

<h3>Answer;</h3>

D. Have different structures and different functions

A plasma membrane and a cell wall have different structures and different functions.

<h3>Explanation;</h3>

Plasma membrane is a structure that is found in both animal cell and plants cells. It is made up of a bi-layer consisting of lipid and proteins. Plasma membrane are semi-permeable which means the allow selective movement of materials in and out of the cell.

Cell wall, on the other hand is a structure that is found on plant cells and lacks in animal cell. It contains cellulose in its structure which enables it to be rigid and enhances it protect the cell from mechanical damage from harsh conditions such as pressure in the outside environment.
