Explain using the particles theory what happens when steam in the bathroom hits a cold surface such as a mirror

The correct equation is (C) H3O+(aq) + C2H3O2−(aq) -> HC2H3O2(aq) + H2O(l). A buffer system is composed of a weak acid and its corresponding salt, effectively stabilizing the pH levels within a solution. The buffer works by adjusting the concentrations of the conjugate acid and base, maintaining the pH constant.

When two atoms with equal electronegativity bond together, they form nonpolar covalent bonds.

Your second statement mirrors the first; the second statement likely reads, "Bonds between two atoms with unequal electronegativity are termed polar covalent bonds."

Clarification:

The Na2 molecules comprise atoms that are connected by a purely covalent bond since both atoms have the same electronegativity.

Metallic bonding only manifests when several atoms cluster together. Such aggregates may not tend to be stable, as larger masses of material typically exhibit greater stability thermodynamically. Therefore, they often merge until a significant metal chunk is formed.

In some ways, metallic bonding can be considered a variant of covalent bonding, but it is more communal—delocalized across numerous atoms—and electron deficient (there are more energy states than available electrons, which contributes to conductive traits). This implies that the term “metallic bond” might appear contradictory, akin to referring to a forest with a single tree.

Response:

a) Representation - (in attachment)

b) The geometry is tetrahedral

c) hybrid orbitals involve sigma bonding.

orbitals arise from the overlap of sulfur's d-orbitals with the p-orbitals of oxygen.

Clarification:

a)

Representation in attachment.

The total charge in both structures is -2. Structure (b) is preferred according to the resonance forms since the formal charges within the species are preserved.

Thus, structure (b) represents the sulfate ion more accurately.

b) In the sulfate ion, the sulfur atom forms connections with four distinct oxygen atoms. Using VSEPR theory, the sulfate ion is tetrahedral in shape.

There are four sigma bonds and no lone pairs surrounding the central atom.

Consequently, the sulfur atom's hybridization is

c)

The s and p orbitals of sulfur undergo hybridization to form sigma bonds. The orbitals involved in bonding are

Therefore, bonds result from the overlapping of sulfur's d-orbitals with the p-orbitals of oxygen.
