HELP ASAP I WILL GIVE BRAINLIST What is the pH of a solution with a 4.60 × 10−4 M hydroxide ion concentration? (4 points)

0.663

3.33

10.1

10.7

10.7

Explanation:

According to this question, we have 4.60 × 10^-4 M hydroxide ion (OH-) concentration.

Since we were given the OH concentration, we first calculate the pOH of the solution, which is given as:

pOH = -log {OH-}

pOH = - log {4.60 × 10^-4}

pOH = - log {0.000460}

pOH = 3.337

pOH = 3.34

Given that; pOH + pH = 14

The pH of the solution = 14 - pOH

pH = 14 - 3.34

pH = 10.66

pH = 10.7

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
