Hi there!
I believe the answer to this is B. Elementary and High school students.
Hope this helps! ☺♥
0001 M HCl is the same as saying that 1 *10-4 moles of H+ ions have been added to solution. The -log[. 0001] =4, so the pH of the solution =4.
The amount of kinetic energu has depens upon an object's speed and its mass.
So its I and IV.
The correct answer is B.
