Answer:
The answer is
<h2>0.63 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5C)
From the question
mass = 47 g
volume = 75 mL
The density is
![density = \frac{47}{75} \\ = 0.626666666...](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B47%7D%7B75%7D%20%20%5C%5C%20%20%3D%200.626666666...)
We have the final answer as
<h3>0.63 g/mL</h3>
Hope this helps you
Answer:
D) energy required to remove a valence electron
Explanation:
Ionization energy can be defined as the atom's ability to and the energy required to remove a valence electron. Ionization energy increases up a group and to the right along a period. So helium has the highest first Ionization energy meaning that it is very hard to remove an electron from helium because octet is already complete.
Answer:
According to the subshells, the ns subshell has a sphere-like shape, and on average, lower energy than the rest of the subshells on the same quantum level
The np subshell has two lobes opposite the origin, and on average has more energy than a ns subshell since it has one more angular node, and thus np electrons are less core-like (and further away from the nucleus).
n
d orbitals have five spatial orientations:
and n
f orbitals have seven spatial orientations
The energies are on average in increasing order for the same energy level , n as follows,
nS < nP < nD < nF
C. ability to bond is a chemical property of tin.
This
electronic transition would result in the emission of a photon with the highest
energy:
4p
– 2s
<span>This
can be the same with the emission of 4f to 2s which would emit energy in the
visible region. The energy in the visible region would emit more energy than in
the infrared region which makes this emission to have the highest energy.</span>
