2. Amid the annular Solar Eclipse visible in India here is a trivia on Solar Eclipse and Chemistry,
French astronomer Pierre Jansen observed the "King of Siam's eclipse", in 1868 from Guntur in Madras state, India. It was the first total eclipse since Gustav Kirchhoff's theory that the Fraunhofer lines in the solar spectrum correspond to the emission line of the different chemical elements present in the Sun. This led to the discovery of X in chemistry, with India witness to it.
3. Founded by the name of Minnesota Mining and Manufacturing Company as a mining venture in Two Harbors, Minnesota. The goal was to mine corundum, but this failed leading to a very vast diversification to a lot of sectors with 3M now holding large number of US patents. Recently, one of its patented products again came in huge demands, due to the coronavirus pandemic and invocation of defense production act in the US. What is that product.
4. Sir Humphrey Davy was chemist who experimented and nicknamed nitrous oxide "laughing gas" and wrote about its potential anaesthetic properties in relieving pain during surgery. He also invented the Davy lamp and a very early form of arc lamp to be used in mines. Also credited to him were first isolation of a number of elements even discovering elemental form of Iodine still, He always joked that X was his greatest discovery. Who is X?
