NH3 is a weak base (Kb = 1.8 × 10–5) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution that is 0.084 M in
kolbaska11 [484]
Answer is: pH of solution is 5,17.
Kb(NH₃) = 1,8·10⁻⁵.
c(NH₄Cl) = 0,084 M = 0,084 mol/L.
Chemical reaction: NH₄⁺ + H₂O → NH₃ + H₃O⁺.
Ka · Kb = 10⁻¹⁴.
Ka(NH₄⁺) = 10⁻¹⁴ ÷ 1,8·10⁻⁵.
Ka(NH₄⁺) = 5,55·10⁻¹⁰.
[H₃O⁺] = [NH₃]  = x.
Ka(NH₄⁺) = [H₃O⁺] · [NH₃] ÷ [NH₄⁺].
5,55·10⁻¹⁰ = x² ÷ (0,084 M - x).
Solve quadratic equation: x = [H₃O⁺] = 6,8·10⁻⁶ M.
pH = -log[H₃O⁺].
pH = -log(6,8·10⁻⁶ M) = 5,17.

Q: How many of the molecules shown contain only one covalent bond?
SVETLANKA909090 [29]

Answer:

cl2 - 1 bond

HCl.- 1 bond

N2 - 3 bond

o2 - 2 bond

  • Cl requires one electron to complete it's octave so it share it's one electron with other chlorine and make a single covalent bond
  • H has one electron and Cl requires one so both form one single bond
  • N requires 3 electrons so it form 3 bonds with other N
  • oxygen requires 2 electrons so it forms 2 bond with other oxygen
