The mean is the average of the sample data, while standard deviation is the average of the differences of each data to the mean. This could only be valid if there is a normal distribution. This distribution pertains to a bell-shaped frequency graph. However, in particle size distribution, the frequency of the sizes is rarely concentrated on the medium or middle size. It may be skewed to the left or skewed to the right. So, the mean and standard deviation is not a good measure for this type of distribution.
Because One Side Is Heaver Then The Other Side
Answer: they are both animals and they live near the yellow stone volcano so basically if the volcano erupts they'll be the first to die.
Explanation:
<u>Answer:</u>
<em>Equivalence point and end point are terminologies in pH titrations and they are not the same.
</em>
<u>Explanation:</u>
In a <em>titration the substance</em> added slowly to a solution usually through a pippette is called titrante and the solution to which it is added is called titrand. In acid-base titrations acid is added to base or base is added to acid.the strengths of the <em>acid and base titrated</em> determines the nature of the final solution.
At equivalence point the <em>number of moles of the acid</em> will be equal to the number of moles of the base as given in the equation. The nature of the final solution determines the <em>pH at equivalence point. </em>
<em>A pH less than 7 will be the result if the resultant is acidic and if it is basic the pH will be greater than 7. </em>In a strong base-strong acid and weak base-weak acid titration the pH at the equivalence point will be 7 indicating <em>neutral nature of the solution.
