Answer: Yes , in
, two electrons from magnesium are transferred to chlorine atoms.
Explanation:
Ionic compound is formed by the transfer of electrons. For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
For example : For formation of ![MgCl_2](https://tex.z-dn.net/?f=MgCl_2)
Electronic configuration of magnesium:
![[Mg]=1s^22s^22p^63s^2](https://tex.z-dn.net/?f=%5BMg%5D%3D1s%5E22s%5E22p%5E63s%5E2)
Magnesium atom will loose two electrons to gain noble gas configuration and form magnesium cation with +2 charge.
![[Mg^{2+}]=1s^22s^22p^63s^0](https://tex.z-dn.net/?f=%5BMg%5E%7B2%2B%7D%5D%3D1s%5E22s%5E22p%5E63s%5E0)
Electronic configuration of chlorine:
![[Cl]=1s^22s^22p^63s^23p^5](https://tex.z-dn.net/?f=%5BCl%5D%3D1s%5E22s%5E22p%5E63s%5E23p%5E5)
Chlorine atom will gain one electron to gain noble gas configuration and form chloride ion with -1 charge.
![[Cl^-]=1s^22s^22p^63s^23p^6](https://tex.z-dn.net/?f=%5BCl%5E-%5D%3D1s%5E22s%5E22p%5E63s%5E23p%5E6)
In Magnesium chloride two electrons from magnesium metal gets transferred to two chlorine atoms and thus
is formed.
The total number of electron pairs that are shared between the two carbon atoms in a molecule of ethyne is 3.

C) The student and desk have to be in contact to apply the force.
Explanation:
I am pretty sure :)
Answer:
<u>Option B is correct</u>
Explanation:
Step 1: Define volatility
In chemistry, the term volatility, is a way to describe how readily a substance transitions from a liquid phase to a gas phase, also called evaporating.
At a given temperature and pressure, a substance with high volatility is more likely to evaporate more quickly , while a substance with a lower volatility is more likely to be a liquid or solid, so not to evaporate or slower.
The higher the volatility, the higher the (vapor) pressure of a compound. Increasing temperature means the vapor pressure will also increase,
Step 2: In this case:
⇒ O<u>ption A is false</u> because the pressure will be higher when volatility is higher.
<u>⇒ Option B is correct</u> because higher volatility means evaporating more quickly
<u>⇒ Option C is false</u> because higher volatility means higher pressure. When pressure increases, the surface tension decreases.
<u>⇒ Option D is false</u> because when the volatility is higher, the liquid/gas escape the container, easier, so there will be less resistance.
