Answer:
D. The sodium ions are separated from the chloride ions, and both dissolve separately into the water.
Explanation:
When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This process is called dissociation.
In other words, In water, the sodium ions become attracted to the negatively-charged oxygen end of the water molecule, and the chloride to the positively-charged hydrogen side, which allows the two ions to become separated, hence dissolve.
An introductory paragraph must and must not contain these things:
Must-
1. Hook/Grabber - Interesting fact, rhetorical question (not recommended), statistic, or just anything (in this case) relating to what your essay is going to talk about that may make the reader more interested. I suggest that you try and make this a little more interesting, such as something relating to Elie and the holocaust to keep the reader interested.
2. Overview of Support - Write what you will further explain in the next paragraphs so that the reader actually knows what they're getting into. It is vital for any article or essay because it helped ease into the writing without any confusion. You should also include shortened reasoning of why your statement is correct/to justify your claim.
Must Not-
1. Very long, dragged out sentences - This will obviously bore the reader. Long and dragged out/descriptive intros will make the reader disinterested and possibly just outright explain what the entire essay is about, which is also a bad sign because it could be considered repetition (which, yes, consistency is key, but seeing the same thing over and over constantly may annoy the reader). You also want to avoid doing this because it takes up more time than it needs to -- remember this is just an introduction!
2. Anything off-topic or unrelated to what your essay/article is about - This means not talking about yourself (especially if it is an informative essay) or talking about your family and the Holocaust (as an example, but not accurate), (etc.) when that is not the main focus of the essay.
This is about all I can think of for now, if you have any further questions, please PM me. Hope I helped and good luck!
