3. 200 ml of 0.2 m hcl is neutralized with 0.1 m
naoh. then during their half neutralization,
what will be the molarity of hci?
a. 0.1 m
b. 0.5 m
c. 0.05 m
d. 1 m

Explanation:

By definition, half neutralization is the point at which half of the acid has been neutralized.

The neutralization reaction that you are studying is the acid-base reaction:

Then, since the starting molarity of the acid (HCl) is 0.2 M, you just need to find half of that concentration:

So, the answer is the first choice: a. 0.1 M.

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.
