Hmmm.. i think B. I dont understand the the answer choices.
Answer:
47.01g/mol
Explanation:
The formula of Nitrous acid is HNO₂:
The formula mass of a compound gives the sum of the atomic masses of the elements that makes up a compound.
Atomic mass of H = 1.0079g/mol
N = 14.0067g/mol
O = 15.9994g/mol
Formula mass of HNO₂ = 1.0079 + 14.0067 + 2(15.9994)
= 1.0079 + 14.0067 +31.9988
= 47.01g/mol
Answer:
D. Hund's rule
Explanation:
Not sure, but I would go with Hund's since it talks about filing electrons in each orbital before you can pair them up. The reason sulfur has lower ionization is because it has one set of paired electrons which makes the orbital unstable whereas phosphorus has 3 unpaired e's which means it is more stable. Thus it is easier to remove electron from sulfur hence lower ionization energy.
