Which of the following atoms would be expected to be diamagnetic in the ground state?
O magnesium (Mg)
O potassiun (K)
O chlorine (CI)
O cobalt (Co)
The atoms that would be expected to be diamagnetic in the ground state is magnesium
The magnetism of an atom refers to its electronic configuration. A diamagnetic atom is an atom whose electrons are all paired.
A paired electron is an electron that occurs in pairs in its orbital shell.
At their respective ground state, the electronic configuration of the given elements are as follows:
The electronic configuration of magnesium is 1s²2s²2p⁶3s². As such its a diamagnetic atom.
The electronic configuration of Potassium is 1s²2s²2p⁶3s²3p⁶4s¹. Hence, Potassium has one unpaired electron in its outermost shell.
The electronic configuration of Chlorine is 1s²2s²2p⁶3s²3p⁵. Hence, Chlorine has one unpaired electron in its outermost shell.
The electronic configuration of Cobalt is 1s²2s²2p⁶3s²3p⁶3d⁷4s². Hence, the unpaired electrons of Cobalt in its outermost shell are three.
Therefore, the atoms that are diamagnetic in the ground state is magnesium.

Explain… What are the subatomic particles of an atom, and where are they located in the atom? Be specific.
Atomic Particles
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

Which Liquid, A or B, would float on top of the other if the two liquids were put in the same container?
Liquid A = 8 g/ml
Liquid B = 3 g/ml
Answer:
liquid B
Explanation:
because of the density of liquid A being 8, liquid B being 3 would be less dense
Calculate the osmolarity of a 1.15% (m/v) KBr solution.
Answer:
1) Convert percent (m/V) to molarity
percent (m/V)=1.15 grams/100ml=1.15 g/0.1L=11.5g/L
molarity of KBr=mol/L=g/L *(1mol/molecular weight of KBr)=(11.5g/L) * (1mol/119.0g/mol)=0.0966 mol/L=0.0966M
2) calculation of osmol from mol
In solution, KBr dissociates into two ions K+ and Br- so there are 2 osmol of KBr per mol
3) calculation of osmolarity=molarity*2=0.0966*2=0.193 Osm or Osmolar

How do you define note-taking and how do you take notes to help you understand the material?
Answer:
Note-taking is simply jotting down the steps to solve specific problems, or listing the resources that can help you when learning something new. In order to take effective notes that can help you understand the material, you can use techniques like Cornell Notes which help you to organize your writing in a way that makes it referable when stuck doing independent work.
List two differences between a map and a giobe
Answer:
1. A map is two dimensional, while a globe is three dimensional
2. A globe is a scaled down representation of the entire Planet Earth. A map can represent an area of any size.
Explanation:
1. A map is usually a sheet of rectangular paper that is a flattened image of an area as seen from the top. A globe on the other hand is a sphere which is a 3D shape.
2. Earth is in the shape of a sphere, so Globes are a smaller representation of the planet. A map can be for a city, state, country, or the world.

If an ionic compound has a 2- charge how does that affect the total number of electrons in a Lewis structure
In the situation where an ion has a charge of -2, the Lewis structure is affected because it must add two additional electrons.
The Lewis structure is a term to refer to the graphical representation that shows the pairs of electrons in dashes or points of bonds between:
The atoms of a moleculeThe lone electron pairs that may existAdditionally, the charge of an ionic compound is calculated using the difference in electrical charge between the electrons. On the other hand, an ion is formed by adding or removing electrons, so the magnitude of the resulting charge depends on the number of electrons added or removed.
According to the above, if an ionic compound has a -2 charge, the Lewis structure must add two electrons.

It moves slowly.
It has a fixed volume.
It can be compressed.
Answer:
it has a fixed volume it can also be compressed
Explanation:
a gases molecules don't move slow because they are not solid and are not compacted.
a gas does not have a fixed shape because there is nothing to hold its shape

Explain why “advancing water contact angles are more sensitive to the hydrophobic property of a surface whereas receding water contact angles are more sensitive to the hydrophilic property of a surface”.
Answer: Surface tension has a more complicated effect on capillary pressure: on the one hand, capillary pressure is directly proportional to surface tension. High surface tension liquids, on the other hand, typically have higher contact angles, which lowers capillary pressure.
