Formal charge for nitrogen atoms I, II, and III, respectively in the azide provided is 0, +1, and -1

A formal charge, in the covalent chemical bonding, refers to the hypothetical charge assigned to an atom in a molecule, based on the assumption that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity. In other words, formal charge is defined as the difference between the number of valence electrons of an atom in a neutral free state and the number assigned to that atom in a Lewis structure. It is given as

Formal charges = Group variance – nonbonding electrons – ½ bonding electron

For the nitrogen atom I,

Formal charges =5 – 2 – ½ (6) = 0

For the nitrogen atom II,

Formal charges =5 – 0 – ½ (8) = 1

Solids known as molecular solids are made up of molecules. Intermolecular forces such as hydrogen bonds, dipole-dipole forces, and dispersion forces hold together molecular solids. Solids with ions as their constituent parts are known as ionic solids. Ion-dipole forces keep ionic solids together.

Atomic solids are those whose constituent atoms make up their entire structure. Atomic solids can be broken down into the three categories below, each of which is held together by a distinct set of forces. Dispersion forces atomic solids is the first category, which only consists of noble gases in their solid states and is held together by coulombic forces that are comparatively weak. Metallic atomic solids fall under the second category, which is held together by nonbonding bonds and contains substances like copper and silver as examples.

The molarity of a solution of HNO3 if 15.72 mL of the solution neutralize 28.2 mL of 0.100 M H2SO4 solution is 0.89 x 10^-4M

Given the volume of HNO3(V1) = 15.72mL

The volume of H2SO4 (V2) = 28.2mL

concentration of H2SO4 (M2) = 0.100M

Concentration of HNO3  = M1

We know that c = n/v where n is the number of moles.

The moles of H2SO4 (n2) = V2 X M2/1000

n2 = 28.2 x 0.100 /1000 = 28. 2 x 10^-4  

From the reaction: H2SO4 + HNO3 -> NO2+ + HSO4- +H2O

We can see from the equation that the number of moles of HNO3 must be half that number, so: n1 = 28. 2 x 10^-4  /2 = 14.1 x 10^-4

The gravitational force of attraction between the two objects would be 1.1858 x [tex]10^{-6[/tex] Newton.

The gravitational force of attraction between two objects of mass m1 and m2 is proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between the two objects.

This is mathematically expressed as follows:

Gravitational force (F) = [tex]Gm_1m_2/d^2[/tex]

Where G is the universal gravitational constant and d is the distance separating the two masses.

In this case:

m1 = 8,000 kg

m2 = 5.0 kg

G = 6.67 x [tex]10^{-11[/tex] N m2 / kg2

d = 1.5 m

F = 6.67 x  [tex]10^{-11[/tex] x 8,000 x 0.5/1.5 x 1.5

Step 2:

CH_3CH_2OBH_3 + D_2O → CH_3CH_2OD + BH_3OH

Step by explanation in  detail

Step 1:

NaBH_4 + CH_3CH_2OH → CH_3CH_2OBH_3 + NaOH

The reaction occurs via a nucleophilic substitution mechanism. The Na^+ cation acts as a spectator ion and does not take part in the reaction. The BH_4- anion acts as the nucleophile, attacking the carbon atom of the CH_3CH_2OH molecule. This causes the C-O bond to break and the BH_3 group to form a bond with the carbon atom. This results in the formation of the CH_3CH_2OBH_3 molecule and the NaOH molecule.

Step 2:

Pressure: Pressure is the force exerted on a substance per unit area. Applying pressure to a substance can change its state from gas to liquid or from liquid to solid.

Amount of Matter: The amount of matter in the system also affects its state. As the amount of matter in the system increases, the particles become more dense and the matter can change state from gas to liquid or liquid to solid.
