What is the pOH of 0.5 M KOH?

Chemistry
1 answer:
jenyasd209 [6]3 years ago
5 0

Answer:

pOH = 0.3

Explanation:

As KOH is a strong base, the molar concentration of OH⁻ is equal to the molar concentration of the solution. That means that in this case:

  • [OH⁻] = 0.5 M

With that information in mind we can<u> calculate the pOH </u>by using the following formula:

  • pOH = -log[OH⁻]
  • pOH = -log(0.5)
  • pOH = 0.3

How does distance affect work pls quick its 15 points pls keep it short pls help!!!!
ra1l [238]
The simple equation used to calculate work is force multiplied by distance, thus as this is the case increasing the distance by a certain amount, assuming the force applied to the object is constant, the amount of work you are doing on the box for instance pushing it, is going to be greater

Since you are pushing the box with the same force covering a greater distance with the force.
