Answer: A substance with a pH of 2 has a 10 times higher concentration of H+ than a substance with a pH of 3.

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration and pOH is calculated by taking negative logarithm of hydroxide ion concentration.

pH=-\log [H^+]

pOH=-log{OH^-}

pH+pOH=14

Given: pH=2

2=-log[H^+]

[H^+]=10^{-2}M

pH=3

3=-log[H^+]

[H^+]=10^{-3}M

A substance with a pH of 2 has a 10 times higher concentration of H+ than a substance with a pH of 3.

If the Earth is round... why is the land flat?
stiv31 [10]

Answer:

See explanation

Explanation:

The land around us appears flat because the Earth is just so unimaginably large, and the curvature is extremely small from our point of view. In reality, the land is slightly bendy, which is why certain structures (like very long bridges) need to be constructed with the curvature in mind, with different ends at slightly different elevations. Hope this helps!

Minchanka [31]
I didn't know if you meant to the power of 14 but if you did here your answer:
3.64 x 10^-19
(you just multiply the frequency by Planck's constant= 6.63 × 10^–34)
