Answer:
-2, -1, 0, +1, +2
Explanation:
The quantum numbers describe the quantum state of an electron in an atom. These numbers are symbolized as n, l, m, and s. There are rules for the combination of these numbers. The angular quantum number (ℓ) is related to the magnetic number (m): if ℓ is equal to a number a, thus m can be any integer number between - a and +a.
According to this rule:
If ℓ = 2, thus m can be have a value of an integer between -2 and +2 ⇒ -2, -1, 0, +1, +2

Solution A has a pH of 3, and solution B has a pH of 5. Which statement best
describes these solutions?
A. Solution B is more acidic than solution A
B. Solution A is acidic, and solution B is basic.
C. Solution B is less acidic than solution A.
O D. Solution A is basic, and solution B is acidic.
Answer:
The answer will be C
Explanation:
Solution A has a pH of 3, and solution B has a pH of 5 "Solution B is less acidic than solution A".
What is pH ?The chemical circumstances of such a solution are reflected by pH, which is an essential quantity. The pH might influence nutritional availability, biological functioning, microbial activity, as well as chemical behavior.
What is acidic?Acidic substances were characterized by a sour flavor. An acid is a molecule that can give an H+ ion while remaining energetically stable.
It is known that if pH ≥7 then solution will be acidic
Hence, solution B is less acidic than solution A.
Therefore, the correct answer will be option (C).

A medallion was dropped into 20.0 mL of water. The water level rose to 25.3 mL. What is the volume of the medallion? (Vobj = Vf - Vi)
Answer:
5.3 mL
Explanation:
We solve this problem using Archimede's principle, which states that the volume displaced by a submerged object is equal to the volume of the object.
With that in mind we calculate the volume of water displaced by the medallion:
25.3 mL - 20.0 mL = 5.3 mLAs the medallion displaced 5.3 mL of water when submerged, the volume of the medallion is also 5.3 mL.

Which compounds can be made with the reaction benzene via electrophilic aromatic substitution using isopropyl chloride and AlCl3 as reagents (1 equivalent or excess).
Answer:
isopropyl benzene (cumene)
Explanation:
The reaction of isopropyl chloride and AlCl3 and benzene belongs to the class of organic reactions known as the Friedel Kraft alkylation.
The mechanism of the reaction involves the formation of a tetrahedral complex [AlCl4]^-.
The electrophile now is the isopropyl group which attacks the benzene to yield the product.

Most representative metal atoms tend to gain enough electrons to attain a stable noble gas (octet) configuration.
True or False
Answer:
False
Explanation:
Non- metals tend to gain electrons easily, metals tend to lose electrons easily
For example, oxygen, a non-gas, when it is an ion, has the option to lose 6 electrons to become like helium, or gain 2 electrons to become like the noble gas neon. However, it becomes like neon for 2 reasons.
A. As a general rule, atoms lose/gain the LEAST amount of electrons.
B. Oxygen is a nonmetal, therefore, to become like a Noble Gas, it would gain, as non-metals usually would, 2 electrons.
What mass of sodium hydroxide would be required to make 1.0L of a 0.75M solution of sodium hydroxide,
NaOH?
Given values are:
Volume, V = 1.0 L or, 1000 mLSolution, M = 0.75 MAs we know the relation,
→ [tex]M = \frac{W}{GM}\times \frac{1000}{V}[/tex]
or,
→ [tex]W = \frac{M\times GM\times V}{1000}[/tex]
By substituting the values, we get
[tex]= \frac{0.75\times 40\times 1000}{1000}[/tex]
[tex]= 30 \ g[/tex]

Which of the following factors does NOT affect surface currents?
A. Coriolis effect
B. density
C. continental deflection
D .wind
The only factors that doesn't affect surface current from the question is B:
density.
Surface currents can be regarded as current that is been formed as a result of Earth's rotation as well as changes in temperature.Surface currents is know as one of the determinant for climate. These currents is responsible for the bringing of warm water from the equator then transfer it to the cooler parts of the ocean as a result of this heat energy is transferred.Some factors that influence surface current are; Coriolis effect : This also aid the movement of the currentcontinental deflection : this helps the deflection of the currents from the continental land masses.wind : without wind there cannot be transfer of the warm water from the equator to the part of the ocean that is cool.Therefore, Option D is correct because density does affect the surface current.

and then _________
Answer:
I’m not sure how they want you to answer the fill in blank.
Explanation:
The Big Bang is a theory where 14 billions years ago all matter and energy in the universe was compressed into an extremely small volume that exploded and began expanding in all directions.
The big bang theory is a hypothesis that states that all matter and energy were compressed into a small volume at one time and then expanded outward.
What is Big Bang Theory?The big bang model of the universe can be described as the model to identify the beginning of the universe. The big bang model is a cosmological model which is described by the software development life cycle.
The Big Bang theory is the dominant model of the observable universe from its beginnings to large-scale evolution. This model explains how the universe is expanded from a state of high density and temperature. It provides an explanation for phenomena, such as cosmic microwave background radiation, the abundance of light elements, and large-scale structure.
Due to the big bang as we know, the universe has been created existing about 12 - 15 billion years ago. According to the theory that the Big bang was a gigantic explosion that formed all of the energy and mass in less than a second in the universe.
