Which is an acceptable Lewis structure for a diatomic nitrogen molecule?

1 answer:

4 0

Answer:
Acceptable Lewis structure of Diatomic Nitrogen Molecule is as follow,

:N≡N:

Explanation:
The given lewis structure is acceptable because each nitrogen atom has a complete octet and and the formal charge of each nitrogen atom is zero. So those lewis structures which has zero or least formal charges are said to be more stable and acceptable. The formal charge is calculated is,

Formal Charge = # of Valence e⁻s - [# of non-bonded e⁻ + 1/2 # of bonded e⁻]

For N,

Formal Charge = 5 - [ 2 + 6/2]

Formal Charge = 5 - [ 2 + 3 ]

Formal Charge = 5 - 5

Formal Charge = 0

Same result will come for the second N atom.

Answer:

$P_2=50kPa$

Explanation:

Hello,

In this case, we can apply the Boyle's law in order to understand the pressure-volume relationship as an inversely proportional relationship relating the initial and the final volume:

$P_1V_1=P_2V_2$

Next, we compute the final pressure P2:

$P_2=\frac{P_1V_1}{V_2}=\frac{100.00kPa*500.0mL}{1000.0mL} \\\\P_2=50kPa$

Thus we validate, the higher the volume the lower the pressure.

Best regards.

If you currently have 1 kg of Uranium^238, in how many years will you have 1/2 kg of Lead^206? PLEASE HELP!!!!!!!

Bogdan [553]

From literature, we would find that the half life of Uranium-238 is equal to 4.5x10^9 years. This is the same number of years to obtain 1/2 kg of Lead-206. Hope this answers the question. Have a nice day.

The ionization of pure water forms _____.

Evgesh-ka [11]

Answer: The ionization of pure water forms hydroxide and hydronium ions.

Explanation:

Ionization is a reaction in the pure water in which water breaks down into its constituting ions that hydronium ion and hydroxide ions.

$H_2O+H_2O\rightleftharpoons H_3O^++OH^-$

One molecule of water looses its proton to form hydroxide ion and l=the lost protons get associated with another water molecule to form hydronium ion.
