Answer:
3.5
Step-by-step explanation:
Given : the hydronium ion concentration is 
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+ =
So, substituting this value in formula :
![pH = - log [3.4*10^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B3.4%2A10%5E%7B-4%7D%5D)
![pH = - log [3.4*0.0001]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B3.4%2A0.0001%5D)
![pH = - log [0.00034]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B0.00034%5D)
pH = 3.468≈3.5
Thus the pH is 3.5
Can I see the full problem from the worksheet?your work looks correct to me.
Answer: The HL Theorem can be used to prove ABR ≅ RCA because both triangles share the same hypotenuse and a leg. The HL theorem states that If the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

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.
