Consider two solutions, solution A and solution B. [H ] in solution A is 500 times greater than that in solution B. what is the difference in the pH values of the two solutions?

-2.70 is the difference in the pH values of the two solutions.

Explanation:

Hydrogen ion concentration in solution A =

Hydrogen ion concentration in solution B =

The pH of solution A: pH

The pH of solution B: pH'

-2.70 is the difference in the pH values of the two solutions.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
