When sodium bonds with chlorine, what is the chlorine electron configuration like?A. any other halogenB. neonC. argonD. radon
Vika [28.1K]

Answer:

C

Explanation:

For sodium to bond with chlorine, it is through electrovalent bonding.

It means , one electron is transferred from the sodium to the chlorine.

Normally, chlorine has 17 electrons, by adding one , we get 18 electrons.

This is the number of electrons for Argon

3. What is the meaning of coordination number?
ryzh [129]

Answer:

Explanation:

Its simple

This is the number of atoms, ions, or molecules that a central atom or ion holds as its nearest neighbours in a complex or coordination compound or in a crystal.

for example: Sodium chloride (NaCl) or table salt is an ionic compound. It means that each cation will have exactly one anion associated with it, which means the cation Na+ and the anion Cl− have the same number of coordinates.

It may be really confusing at first

I recommend you go online and watch tutorial  videos on the topic

Calculate to three significant digits the density of chlorine pentafluoride gas at exactly and exactly . You can assume chlorine
slega [8]

Answer:

Density is 6.16g/L

Explanation:

<em>... at exactly -15°C and exactly 1atm...</em>

<em />

Using general gas law:

PV = nRT

We can find density (Ratio of mass and volume) in an ideal gas as follows:

P/RT = n/V

<em>To convert moles to grams we need to multiply the moles with Molar Weight, MW:</em>

n*MW = m

n = m/MW

P/RT = m/V*MW

P*MW/RT = m/V

<em>Where P is pressure: 1atm;</em>

<em>MW of chlorine pentafluoride: 130.445g/mol</em>

<em>R is gas constant: 0.082atmL/molK</em>

<em>And T is absolute temperature: -15°C+273.15 = 258.15K</em>

<em />

Replacing:

P*MW/RT = m/V

1atm*130.445g/mol / 0.082atmL/molK*258.15K = m/V

6.16g/L = m/V

<h3>Density of the gas is 6.16g/L</h3>

Do you feel that people’s safety is compromised when they live near a nuclear power plant? Why or why not? What sort of informat
Olegator [25]
So, personally, I think it's not that safe to live right by a nuclear plant because it contains radioactive energy and that is unhealthy to the human body. Living by one a person should also take the precautions that it could have a malfunction and that could cause a fatal accident, an explosion. With that radioactive energy is released and both ruins the area and destroys everything. Well my answer is not that great but I hope this helps.
