Answer : The correct option is, (B) Magnesium nitride

Explanation :

Mg_3N_2 is an ionic compound because magnesium element is a metal and nitrogen element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

The naming of ionic compounds is given by :

  • Cation is written first.
  • The anion is written next and a suffix is added at the end of the anion. The suffix written is '-ide'.

Thus, the name of Mg_3N_2 is magnesium nitride.

Therefore, the correct option is, (B) Magnesium nitride

Which molecule is usually comprised of six carbons in a ring (with six sides)?
Oksana_A [137]
The hydrocarbon is usually named using the prefix that would indicate or entail how many carbon are present in it. For six carbons, the name would begin with hexa-. For cyclic molecule, the name would begin further with cyclo-. Thus, for the molecule that is described above, the name would be, cyclohexane. 

Another, more well-known, component is the cyclic molecule with alternating double bonds, this will be named, benzene.

What happens to electrons in ionic bonds?
vlabodo [156]

Answer:

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Hope this helps :)

A gas at 300 k and 4.0 atm is moved to a new loacation with a temperature of 250 k. The volume changes from 5.5 L to 2.0 L. What
alexgriva [62]
Answer is: <span>the pressure of the gas is 9,2 atm.
</span>p₁ = 4,0 atm.
T₁ = 300 K.
V₁ = 5,5 L.
p₂ = ?
T₂ = 250 K.
V₂ = 2,0 L.
Use combined gas law - the volume of amount of gas is proportional to the ratio of its Kelvin temperature and its pressure.<span> 
</span>p₁V₁/T₁ = p₂V₂/T₂.
4 atm · 5,5 L ÷ 300 K  = p₂ · 2,0 L ÷ 250 K.
0,0733 = 0,008p₂.
p₂ = 9,2 atm.
