Answer:

Both have a pH greater than 7, but NH₃ has a lower pH than KOH.

Explanation:

  • Both of NH₃ and KOH are bases (can produce OH⁻), so both have a pH greater than 7.
  • NH₃ is considered as a weak base (not completely ionized), while KOH is a strong base (completely ionized).
  • If both NH₃ an KOH has the same concentration, KOH produces OH⁻ higher than that of NH₃.
  • So, NH₃ has a lower pH than KOH.

  • Thus the right choice is:

<em>Both have a pH greater than 7, but NH₃ has a lower pH than KOH.</em>

<em></em>

polet [3.4K]

Answer:

12.09 L

Explanation:

Step 1: Convert 826.1 mmHg to atm

We will use the conversion factor 760 mmHg = 1 atm.

826.1 mmHg × 1 atm/760 mmHg = 1.087 atm

Step 2: Convert 427.8 J to L.atm

We will use the conversion factor 101.3 J = 1 L.atm.

427.8 J × 1 L.atm/101.3 J = 4.223 L.atm

Step 3: Calculate the change in the volume

Assuming the work done (w) is 4.223 L.atm against a pressure (P) of 1.087 atm, the change in the volume is:

w = P × ΔV

ΔV = w/P

ΔV = 4.223 L.atm/1.087 atm = 3.885 L

Step 4: Calculate the final volume

V₂ = V₁ + ΔV

V₂ = 8.20 L + 3.885 L = 12.09 L
