Discuss the function of cobalt in action of vitamin B12 and its derivatives and how cobaloximes serve as models for the biologic
S_A_V [24]

Answer:

Cobalt and its derivatives act as a catalyst for some enzymatic functions, in this case, it acts as a cofactor.

Cobaloximes are effective electrocatalysts for the production of hydrogen and, therefore, functional models for hydrogenases.

Explanation:

Cobalt is a metal that participates directly in the synthesis of vitamin B12, necessary for the metabolism of various proteins, with megaloblastic anemia being one of the greatest evidences of a lack.

Its main function is that it integrates the vitamin B12 molecule, also called cyanocobalamin, so that lack of cobalt causes the same symptoms as vitamin B12 deficiency.

Vitamin B12 can only be synthesized by bacteria and for this a cobalt atom is required, in fact adult ruminants can synthesize enough vitamin B12 in the rumen provided they have an adequate supply of cobalt.

It acts as a catalyst for some enzymatic functions, in this case, it acts as a cofactor. Very important for example in the transfer of methyl groups, in this way cobalt, together with folic acid participate in the synthesis of methionine.

The dimethylglioxime (dmgH) complexes to the cobalt to give a series of complexes of Co (III), called cobaloxime, that having 4 positions coordinated to nitrogen in a coplanar way and forming a ring similar to the corrínico nucleus; If another substituent also has an N-heterocyclic nature, it can correctly simulate the B12 system.

Iron filling's were mixed together with salt crystal's What unique property of iron would be BEST to separate the fillings from
Leto [7]

Answer:

Magnetic property

Explanation:

Iron filling is a magnetic compound, unlike the salt crystals. This means they are attracted by magnets.

To separate a mixture of iron filling s and salt crystals, a magnet should be used to remove the iron fillings from the mixture.

What are the possible values of ml for l=2<br> ​
Marrrta [24]

Answer:

-2, -1, 0, 1, 2

Explanation:

There are four types of quantum numbers;

1) Principal quantum number (n)

2) Azimuthal quantum number (l)

3) magnetic quantum number (ml)

4) Spin quantum number (s)

The azimuthal quantum number (l) describes the orbital angular momentum and shape of an orbital while the magnetic quantum number shows the projections of the orbital angular momentum along a specified axis.  This implies that the magnetic quantum number shows the orientation of various orbitals along the Cartesian axes. The values of the magnetic quantum  number ranges from -l to + l

For l= 2, the possible values of the magnetic quantum number are; -2, -1, 0, 1, 2

Why do gases diffuse more quickly than liquids?
Alborosie

Answer:

D)Gas particles move rapidly and have space between them.

Explanation:

Matter exists in three states namely: solids, liquids and gases. The particles contained in these three states are different from one another. In the gaseous state, the particles are FAR APART from one another i.e. space exists and they move at a very fast rate in contrast to the particles of a liquid, which have less space and move slower.

This rapid movement of gas particles within a less restricted space accounts for the reason why gaseous substances DIFFUSE more quickly than liquids.
