Lelu [443]

Answer:

3.5

Step-by-step explanation:

Given : the hydronium ion concentration is 3.4*10^{-4} in orange juice

To Find: what is the pH?

Solution :

Definition of pH : pH is the negative log of the molar hydrogen ion concentration

Formula of pH : - log [H+]

Since we are given H+ =  3.4*10^{-4}

So, substituting this value in formula :

pH = - log [3.4*10^{-4}]

pH = - log [3.4*0.0001]

pH = - log [0.00034]

pH = 3.468

pH = 3.468≈3.5

Thus the pH is 3.5

ExtremeBDS [4]

Answer:

Mauna Kea has from the base that is to say the deepest 10 km of height that is to say 10,000 m which is equivalent to being higher than Mount Everest.jj

Step-by-step explanation:

 The main reason why we could say that Mauna Kea is the highest mountain, even surpassing Mount Everest, is because of its altitude if we compare them we see the difference; for example Mauna Kea from its base that is to say from the deepest the ocean measures 10,000 m of altitude, on the other hand the Mount Everest has an altitude of 8848 meters (29,029 ft) above sea level, that is to say from its base it measures 8848 m altitude.
