If the balloon described in Question 10.24 is released into the air and rises to an altitude of 10,000 ft where the atmospheric
1 answer:
The new volume will be 33.5 L.
Explanation:
The kinetic theory of gases indicates that the space occupied by gas molecules is directly proportional to their temperature while being inversely proportional to the pressure. Assuming the number of moles is n = 1, the equation for gases can be written as:
PV = nRT
In this equation, P stands for pressure, V represents volume, R is the gas constant, and T denotes temperature.
Given that P = 523 Torr, T = 7.50 °C = 7.50 + 273.15 = 280.65 K, and the gas constant R = 62.363 Torr L mol⁻¹K⁻¹.
Consequently, the new volume will be 33.5 L.

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.
