Compounds usually have the same properties as the bonds they are made from true or false

gavmur [86]

Well , I will say this is a false statement.
This is because compounds which were all made by the same bond have same physical properties but different chemical properties.

Chemical Properties :
How do the subtances react with ( water, acid,alkaline, base , gas like oxygen, etc. )

Physical Properties :
- Solubility of those subtances in (water or organic solvent )
- Electric Conductivity
- Melting or Boiling Point
- Density
- Smell (exp : Ammonia has pungent smell , Esters has fruity smell)

SpyIntel [72]

8760 hours in a year 525600 minutes in one year 8760 times 60 equals 525600 minutes now multiply that by 5 to get 2628000 minutes

If a sound wave speeds up and its frequency does not change, what happens to the wavelength?

yan [13]

Answer: No, the speed of propagation is constant in a given medium; only the wavelength changes as the frequency changes.

Two electrons are found in the same atom. One has the quantum number set (3, 2, 0, +?), and the other has the quantum number set

Vilka [71]

D. Same energy level but different sublevel.

<h3>Explanation</h3>

There are four quantum numbers [1]:

n, the principal quantum number,
l, the orbital angular momentum quantum number,
 $m_l$ , the magnetic quantum number, and
$m_s$ , the electron spin quantum number.

As their names might suggest:

n determines the main energy level of an electron.
l determines the type of sublevel of an electron.
Each sublevel might contain more than one orbital. $m_l$ gives the orbital of an electron.
Each orbital contains up to two electrons. $m_s$ tells two electrons in the same orbital apart.

The two electrons in question come from the same atom. The question suggests that they have the same n, $m_l$ , and $m_s$ . As a result, both electrons are in main energy level n = 3. They share the same spin.

However, the two electrons differ in their value of l.

l = 2 for the first electron. It belongs to a d sublevel.
l = 1 for the second electron. It belongs to a p sublevel.
