SO3 2-DOES  show delocalized bonding

delocalized bonding occurs when there is a resonance structure and the electronic bonds are a delocalised "cloud" around the species

The resonance effect of the sulfite sructures ithe folowing link:

Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ions or polyatomic atoms. Therefore SO₃²⁻ show delocalized bonding.

Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.

Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state.

SO₃²⁻ show delocalized bonding as there is a resonance structure and the electronic bonds are a delocalized "cloud" around the species

Therefore SO₃²⁻ show delocalized bonding.

Not all acid-catalyzed conversions of alcohols to alkyl halides proceed through the formation of carbocations. Primary alcohols and methanol react to form alkyl halides under acidic conditions by an SN2 mechanism.

Not all acid-catalyzed conversions of alcohols to alkyl halides proceed through the formation of carbocations. Primary alcohols and methanol react to form alkyl halides under acidic conditions by an SN2 mechanism.

In these reactions the function of the acid is to produce a protonated alcohol. The halide ion then displaces a molecule of water (a good leaving group) from carbon; this produces an alkyl halide:

Again, acid is required. Although halide ions (particularly iodide and bromide ions) are strong nucleophiles, they are not strong enough to carry out substitution reactions with alcohols themselves. Direct displacement of the hydroxyl group does not occur because the leaving group would have to be a strongly basic hydroxide ion:

We can see now why the reactions of alcohols with hydrogen halides are acid-promoted.

Carbocation rearrangements are extremely common in organic chemistry reactions are are defined as the movement of a carbocation from an unstable state to a more stable state through the use of various structural reorganizational "shifts" within the molecule. Once the carbocation has shifted over to a different carbon, we can say that there is a structural isomer of the initial molecule. However, this phenomenon is not as simple as it sounds.

B. dust particles are absorbing light

When light travels through a medium, it interacts with the medium and this causes the scattering of light. - Photons are absorbed by molecules in the medium, and this causes the molecules to vibrate and then re-emit the photons. ... - The scattering of light increases with frequency

Answer:

C

Explanation:

1 Electrolytes, particularly sodium, help maintain fluid balance through osmosis. Osmosis is a process where water moves through the wall of a cell membrane from a dilute solution (more water and fewer electrolytes) toward a more concentrated solution (less water and more electrolytes).

2 acid base balance in the body

our body's pH balance, also referred to as its acid-base balance, is the level of acids and bases in your blood at which your body functions best. The human body is built to naturally maintain a healthy balance of acidity and alkalinity. The lungs and kidneys play a key role in this process.

Explanation:

There are 8 carbon atoms in the reactants' side, because you multiply the 2 in front of C4H10 and the 4 under the C atom, and that gives you 8. So, 8 carbon atoms.

Answer:

Covalent bond

Explanation:

All the characteristics of a Covalent bond are being described.

When, a substance boils at 45degree C. Then, the most likely bond type for the given substance is a covalent bond. Option A is correct.

Liquid at Room Temperature: The fact that the substance is a liquid at room temperature suggests that the intermolecular forces holding its molecules together are relatively weak. Covalent compounds often have weaker intermolecular forces compared to ionic or metallic compounds.

Doesn't Conduct Electricity When Dissolved in Water: Covalent compounds, in general, do not conduct electricity when dissolved in water. This is because they do not dissociate into ions in solution, which is necessary for electrical conductivity. Ionic compounds, on the other hand, typically dissociate into ions and can conduct electricity in solution.

Boils at 45°C: The relatively low boiling point (45°C) indicates that the intermolecular forces in the substance are weak. Covalent compounds tend to have lower boiling points compared to ionic or metallic compounds, which often have stronger bonding.

Considering these factors, the substance is likely held together by covalent bonds, which involve the sharing of electrons between atoms. This allows for the formation of discrete molecules with weak forces between them.

Hence, A. is the correct option.

Answer:

The concentration of H⁺ in a 2.5 M HCl solution is 2.5 M

Explanation:

As HCl is a strong acid and hence a strong electrolyte, it will dissociate as

HCl ⟶ H⁺ + Cl⁻

So, The concentration of H⁺ will be 2.5 M (same as HCl)

Thus, The concentration of H⁺ in a 2.5 M HCl solution is 2.5 M

Explanation:

The crystal size of an igneous rock is described as it's texture

The heat of vaporization of CH3CN is obtained from the question as 25 KJ/mol.

We can obtain the number of moles from;

PV = nRT

P = 1 atm

V = 1.17 L

n = ?

R = 0.082 atm LK-1mol-1

T = 81.6 °C + 273 = 354.6 K

n = PV/RT

Substituting values;

n =  1 atm × 1.17 L/0.082 atm LK-1mol-1 × 354.6 K

n = 0.04 moles

Using; q = n·ΔHv

q = Heat absorbed

n = number of moles

Hv  = Heat of vaporization

ΔHv = q/n

ΔHv = 1.00 × 10^3/0.04

ΔHv = 25 KJ/mol
