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:
The unit of molar concentration is M.
To prove your answer you can take the logarithm of 0.0316:
Can you please post the whole question and show the prism as well?
Answer:
Velocity
Explanation:
In the context of speed, this refers to the change of position in a fixed amount of time, and velocity provides more depth to that; it also gives direction, which makes sense when you eventually learn that the velocity is the derivative of the position.
In physics, velocity is prevalently used.
