Answer:
2.28 atm
Explanation:
V₁ = 2.33L, V₂ = 1.08L
T₁ = 289K, T₂ = 304K
P₁ = 1.05 atm, P₂ = ?
Where V₁ and V₂ are initial and final volume respectively
T₁ and T₂ are initial and final temperature respectively
P₁ and P₂ are initial and final pressure respectively
The formula to be used here is the general gas equation:
P₁V₁/T₁=P₂V₂/T₂
1.05 × 2.23/289 = P₂ × 1.08/304
P₂ × 1.08 × 289 = 1.05 × 2.23 × 304
P₂ = (1.05 × 2.23 ×304) ÷ (1.08 × 289)
P₂ = 711.82 ÷ 312.12
P₂ = 2.28 atm
Answer:
A). half, higher
Explanation:
The Formal charge is elaborated as the 'allocated charge to a molecules' atom' on the basis of the assumption that the electrons present in the chemical bond are equally split among the atoms. It is estimated by 'halving the no. of bonding electrons that encircle the atom.
While Oxidation number is characterized as the 'hypothetical charge of an atom that is present within a molecule.' It is also defined as 'the actual number of lost or gained electrons or the rate at which the electrons are gained or lost by an atom to develop a chemical bond along with the other atom.' It is <u>calculated by allocating or sharing the electrons having the higher electronegativity belonging to a specific bond with the other</u>. Thus, <u>option A</u> is the correct answer.
Lead (Pb) has the electron configuration [xe] 6s2 4f14 5d10 6p2.
<h3><u>
What is electronic configuration ?</u></h3>
A neutral element's total number of electrons is represented by its electronic configuration. To get the total number of electrons in an atom, we sum all the superscripts.
As the last electron enters the p orbital, the provided element is a p block element. Xenon, a noble gas with 54 electrons, is the closest.
According to Afbau's rule, the electrons are filled in the sequence of increasing energies, and the electronic configuration in terms of the noble gs configuration is as follows:
Total electrons = 54 + 2 + 14 + 10 + 2 = 82
Lead is the element with the symbol whose atomic number is 82 since it contains 82 electrons.
