What is the H+ concentration when pH is 2, 6, 7, 8, and 12?
Mariulka [41]

Answer:

See below.

Explanation:

pH = - log (H+)

So the pH of 1 x 10^-7 M solution is 7.

I'm sorry but I'm not sure about what the other units mean, so Im not sure of the answer to those.

If you convert the other units to the form  1 x 10^-n  then the pH will be n.

What do we call the amount of energy required to change from a liquid to a gas?
rewona [7]
Hello!

When something is a liquid then turns to a gas, this is known as evaporating so we would call it the heat of evaporation or also known as latent heat. Just remember liquid to gas is vapor! 

I hope this helped!

I am, yours most sincerely,
