Nitrogen gas (N₂) reacts with hydrogen gas (H₂) to form ammonia (NH₃). At 200°C in a closed container, 1.0 atm of nitrogen gas i
Pie

Answer:

The partial pressure of hydrogen gas at equilibrium is 1.26 atm

Explanation:

Let's use the molar fraction to solve this:

Molar fraction = Moles of gas / Total moles

Molar fraction = Gas pressure / Total pressure

Without equilibrium, we can think that the total system pressure is the sum of the partial pressures of each gas.

1 atm N₂ + 2 atm H₂ = 3 atm

Molar fraction for H₂ = 2 atm / 3atm → 0.66

Let's replace the molar fraction in equilibrium

Gas pressure / 1.9 atm = 0.66

Gas pressure = 1.26atm

The statement comparing ionic and covalent bonds which is correct is; Choice B; Covalent bonds tend to be less polar than ionic bonds

  • Although, covalent bonds between atoms of different elements are characterized as polar bonds, but the degree of polarity varies widely. Some bonds between different elements are only minimally polar, while others are strongly polar.

Ultimately, Ionic bonds can be considered the extreme in polarity, with electrons being transferred rather than shared.

  • Ionic bonds are formed between highly electropositive elements (metals) and highly electronegative elements (non-metals).

  • Covalent bonds are characterized by the the sharing of electrons between atoms unlike the complete transfer of electrons in ionic bonds.

Among the choices, the statement which is correct when comparing covalent bond to ionic bond is: Choice B: Covalent bonds tend to be less polar than ionic bonds.
