Is there an N−Cl bond in solid ammonium chloride?
Tems11 [23]
When ammonia is reacted with HCl it abstracts proton from acid and forms Ammonium Ion and Chloride Ion.

                              NH₃  +  HCl   →   ⁺NH₄  + Cl⁻ (simply Written NH₄Cl)
Structure,
              The structure of Ammonium Chloride is among those structures which contains all three types of bonding's, i.e.
                                  
                                                Ionic Bond

                                                Covalent Bond

                                                Coordinate Covalent Bond

Three Hydrogen atoms previously bonded with Nitrogen are covalent in nature. The new incoming proton from HCl forms co-ordinate covalent bond with Nitrogen and Chloride Ion containing negative charge make Ionic Bond with the positive Ammonium Ion. In question, if the line between Nitrogen and Chlorine atom is assumed covalent then it is incorrect. Structure is shown below,

If 1.20 moles of an ideal gas occupy a volume of 18.2 l at a pressure of 1.80 atm, what is the temperature of the gas, in degree
scoundrel [369]

We can calculate for temperature by assuming the equation for ideal gas law:

P V = n R T

Where,

P = pressure = 1.80 atm

V = volume = 18.2 L

n = number of moles = 1.20 moles

R = gas constant = 0.08205746 L atm / mol K

Substituting to the given equation:

T = P V / n R

T = (1.8 atm * 18.2 L) / (1.2 moles * 0.08205746 L atm / mol K)

T = 332.70 K

We can convert K unit to ˚C unit by subtracting 273.15 to Kelvin, therefore

T = 59.55 ˚<span>C</span>

Which choice represents a pair of resonance structures? Note that lone pairs have been omitted for clarity. View Available Hint(
stepladder [879]

Answer:

A. O=C=O and O≡C−O

Explanation:

Resonance:                                                                                                                

          When the electron distribution on the molecule become uneven like one molecule have more electron compare to other.Resonance occurs due to overlap of the orbitals.When electron flow through pi system then resonance occurs.

So the option A is correct.

A. O=C=O and O≡C−O
