Purposeful <span>Opening but with a good direction Open questions require more than a yes or no answer. </span>Encourages higher levels of thinking – Not all questions are created equal. A question that facilitates critical thinking and processing is of more value than a “got it” question (questions that are usually a repetition of content presented by the lecturer).http://blog.lifeway.com/explorethebible/blog/5-characteristics-of-a-good-question/
Answer:
no
Explanation:
due to the refraction of light,meaning bending of light when it passes from diffrent mediums with diffrent densities
(probably mot the complete ans but smtg like this)
<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.

The air mass that originates over land in Canada is most likely to be cold and dry
<u>Explanation:</u>
- The air masses overland from a continent is usually Dry. The air masses are formed by the uneven warming and cooling of the surface of the earth by the sun gives rise to air masses.
- Canada is affected by the five air masses they are Continental Arctic, Maritime Arctic, Maritime polar, Maritime tropical, and Continental Tropic.
- As Canada is most likely affected by the Continental Arctic the air masses are cold and dry.
