Answer:
For this angular momentum, no quantum number exist
Explanation:
From the question we are told that
The magnitude of the angular momentum is 
The generally formula for Orbital angular momentum is mathematically represented as

Where
is the quantum number
now
We can look at the given angular momentum in this form as

comparing this equation to the generally equation for Orbital angular momentum
We see that there is no quantum number that would satisfy this equation
Mole percent is the percentage of the total moles that is of a particular component.
Answer:
d
Explanation:
HF gives its H to HPO42 making it H2PO4, so HF is the acid and F- is the conj base
More specifically two atoms but this is indeed true. The elements do not need to be different but there can only be two atoms. The prefix indicates the quantity of two. Di - means "of two".
