Answer:
Explanation:
The acidity of a solution is measured by its pH, which is the logarithm of the inverse of the molar concentration of hydronium (H₃O⁺) ions:
- pH = log 1 / [H₃O⁺] = - log [H₃O⁺]
When you know the pH value you can find hydronium concentration using the antilogaritm function:
![pH=-log[H_3O^{+}]\\ \\ {[H_3O^+]}=10^{-pH}\\ \\ {[H_3O^+]}=10^{-2.50}\\ \\ {[H_3O^+]}=0.0032](https://tex.z-dn.net/?f=pH%3D-log%5BH_3O%5E%7B%2B%7D%5D%5C%5C%20%5C%5C%20%7B%5BH_3O%5E%2B%5D%7D%3D10%5E%7B-pH%7D%5C%5C%20%5C%5C%20%7B%5BH_3O%5E%2B%5D%7D%3D10%5E%7B-2.50%7D%5C%5C%20%5C%5C%20%7B%5BH_3O%5E%2B%5D%7D%3D0.0032)
The unit of molar concentration is M.
To prove your answer you can take the logarithm of 0.0316:
<h2><em>Summary: Jupiter is the largest and widest planet in the solar system. Jupiter's moon name is Europa. Jupiter only has one 79 moons that we know of. Jupiter is the 5th planet from the sun.Jupiter’s mass is 318 times larger than Earth.A year on Jupiter is equal to 11.9 Earth Years.</em></h2>
Ionic compound is formed by negative and positive ions, these ions form ionic bond
Answer: C the study of living things
Explanation:
A closed economy<span> is self-sufficient, meaning no imports are brought in and no exports are sent out, the goal being to provide consumers with everything they need from within the </span>economy's borders. An example would be how <span>Brazil's is an unusually </span>closed economy<span> as measured by trade penetration, with exports plus imports equal to just 27.6 per cent of GDP in 2013.</span>
