Answer:
if you did it would probably make it bigger...
Explanation:
:)
Here we have to get the 
of the reaction at 520 K temperature.
The of the reaction is 1.705 atm
We know the relation between and 
is 
, where = The equilibrium constant of the reaction in terms of partial pressure, = The equilibrium constant of the reaction in terms of concentration and N = number of moles of gaseous products - Number of moles of gaseous reactants.
Now in this reaction, PCl₃ + Cl₂ ⇄ PCl₅
Thus number of moles of gaseous product is 1, and number of moles of gaseous reactants are 2. Thus N = |1 - 2| = 1 mole
The given value of is 4.0×10⁻²
The molar gas constant, R = 0.082 L. Atm. mol⁻¹. K⁻¹ and temperature, T = 520 K.
On plugging the values in the equation we get,
Or, = 1.705 atm
Thus, the of the reaction is 1.705 atm
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>

D all of these I’m about 99% sure
