How is the composition of a meteorite relevant to finding out the composition of earth’s core?

2 answers:

Since the belief is that the Earth was formed by an
enormous number of collisions of meteors, the
iron would have collected at the core due to its
mass. Many meteorites are about the same age as
the solar system so they may resemble the
material at the core.

Explanation:

Since scientists think planets and meteorites were made at the same time and in the same place, it seems logical that whatever a meteorite is made of is also what planets are made of.

V125BC [204]

Answer:

Following are the solution to the given question:

Explanation:

Each method through KHP is somewhat more precise since we have weighed that requisite quantity, we exactly know the KHP intensity appropriately. Its initial 6 M HCl concentration was never considered mandatory. They have probably prepared 6 M HCl solution although long ago and could have changed its concentration over even a period.

Specify which atoms, if any, bear a formal charge in the Lewis structure given and the net charge for the species.

ozzi

Answer :

Formal charge on C: (-1)

Formal charge on N: (0)

Net charge: (-1)

Explanation :

First we have to determine the Lewis-dot structure of $CN^-$ .

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, $CN^-$

As we know that carbon has '4' valence electrons and nitrogen has '5' valence electrons.

Therefore, the total number of valence electrons in $CN^-$ = 4 + 5 + 1= 10

According to Lewis-dot structure, there are 6 number of bonding electrons and 4 number of non-bonding electrons.

Now we have to determine the formal charge for each atom.

Formula for formal charge :

$\text{Formal charge}=\text{Valence electrons}-\text{Non-bonding electrons}-\frac{\text{Bonding electrons}}{2}$

$\text{Formal charge on C}=4-2-\frac{6}{2}=-1$

$\text{Formal charge on N}=5-2-\frac{6}{2}=0$

Net charge = -1 + 0 = -1

On the basis of oxidation number consideration which of the following does not react with molecular oxygen no ,n2o,so2,so3,p4o6

sesenic [268]

N oxidation number in N₂O = 1
S oxidation number in SO₂ = 4
S oxidation number in SO₃ = 6
P oxidation number in P₄O₆ = 3
Therefore, the Sulfur in SO₃ will not react with molecular oxygen as Sulfur is already using all of its valence electrons in bonding.
