Explain why iodine is an appropriate name for the element discovered by Bernard Courtois. Write at least 3 sentences.

Answers

Answer 1

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

mention the obstacles to the modernization of agriculture in Nepal​

Answers

Answer:

Hello friend heres your answer……..

Explanation:

Although Nepal's economy is mainly focused on agriculture, it faces many problems and obstacles to modernizing agriculture. The first obstacle is that the country has a low investment in technology, which prevents farmers from having access to new resources aimed at agriculture, causing them to be stuck with traditional agricultural systems and elements.

These traditional agricultural systems do not allow high productivity of crops, causing crops to be low, sales to be low and economic gain to be weak, preventing farmers from investing in better production methods.

Other challenges to this modernization are the lack of investment in research, the lack of efficient transport, the lack of a good irrigation system and a limited market.
