A 1 liter solution contains 0.227 M acetic acid and 0.302 M potassium acetate. Addition of 0.113 moles of sodium hydroxide will: (Assume that the volume does not change upon the addition of sodium hydroxide.)

(e) No Change on pH

Explanation:

The question is not complete. The completed question is;

A 1 liter solution contains 0.227 M acetic acid and 0.302 M potassium acetate. Addition of 0.113 moles of sodium hydroxide will:

(a) Raise the pH

(b)lower the pH

(c) Raise the pH by several unit

(d) lower the pH by several unit

(e) No Change on pH

The mixture of 0.227 M acetic acid and 0.302 M potassium acetate, gives a buffer solution.

The mixture resists change in pH when the Sodiumhydroxide is added

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
