Explain why iodine is an appropriate name for the element discovered by Bernard Courtois. Write at least 3 sentences.
Explanation:
In 1811 the French chemist Bernard Courtois obtained a violet vapour by heating seaweed ashes with sulfuric acid as a by-product of the manufacture of saltpetre. This vapour condensed to a black crystalline substance, which he called “substance X.” In 1813 British chemist Sir Humphry Davy, who was passing through Paris on his way to Italy, recognized substance X as an element analogous to chlorine; he suggested the name iodine from the Greek word ioeides, “violet coloured.”

Occurrence and distribution
Iodine is never found in nature uncombined, and it is not concentrated sufficiently to form independent minerals. It is present in seawater, but sparingly, as the iodide ion, I−, to the extent of approximately 50 mg per metric ton (0.0016 ounce per ton) of seawater. It is also formed in seaweeds, oysters, and cod livers. Sodium iodate (NaIO3) is contained in crude Chile saltpetre (sodium nitrate, NaNO3). The human body contains iodine in the compound thyroxine, which is produced in the thyroid gland.
The only naturally occurring isotope of iodine is stable iodine-127. An exceptionally useful radioactive isotope is iodine-131, which has a half-life of eight days. It is employed in medicine to monitor thyroid gland functioning, to treat goitre and thyroid cancer, and to locate tumours of the brain and of the liver. It is also used in investigations to trace the course of compounds in metabolism. Several iodine compounds are used as contrast mediums in diagnostic radiology. In aqueous solution even minute amounts of iodine in the presence of starch produce a blue-black colour

Constitution
B. Make the process of changing the Constitution as easy as
possible
C. Ensure that state governments submit to federal authority under
the Constitution
D. Allow the Constitution to be updated to suit changing times
Answer:
D
Explanation:
It doesn't prevent small political groups from blocking changes to the Constitution because the amendment was approved by a higher percentage of states than the House and Senate.
It doesn't make the process of changing the Constitution as easy as possible because it still needs to go through many stages of approval.
It doesn't ensure that state governments submit to federal authority under the Constitution because, again, the state had a higher percentage in vote.
So, D must be the correct answer; with the collective view of the states, house and senate, the amendment can reflect the needs of the time.
