Ostwald process

The Ostwald process is a chemical process used for making nitric acid. Wilhelm Ostwald developed the process, he patented it in 1902; the Ostwald process is a mainstay of the modern chemical industry, it provides the main raw material for the most common type of fertilizer production. And the Ostwald process is associated with the Haber process, which provides the requisite raw material, ammonia. Ammonia is converted to nitric acid in 2 stages, it is oxidized by heating with oxygen in the presence of a catalyst such as platinum with 10% rhodium, platinum metal on fused silica wool, copper or nickel, to form nitric oxide and water. This reaction is exothermic, making it a useful heat source once initiated: 4 NH 3 + 5 O 2 ⟶ 4 NO + 6 H 2 O Stage two encompasses two reactions and is carried out in an absorption apparatus containing water. Nitric oxide is oxidized again to yield nitrogen dioxide; this gas is readily absorbed by the water, yielding the desired product, while reducing a portion of it back to nitric oxide: 2 NO + O 2 ⟶ 2 NO 2 3 NO 2 + H 2 O ⟶ 2 HNO 3 + NO The NO is recycled, the acid is concentrated to the required strength by distillation.

Alternatively, if the last step is carried out in air: 4 NO 2 + O 2 + 2 H 2 O ⟶ 4 HNO 3 Typical conditions for the first stage, which contribute to an overall yield of about 98%, are: pressure is between 4–10 standard atmospheres and temperature is about 870–1,073 K. A complication that needs to be taken into consideration involves a side-reaction in the first step that reverts the nitric oxide back to nitrogen: 4 NH 3 + 6 NO ⟶ 5 N 2 + 6 H 2 O This is a secondary reaction, minimised by reducing the time the gas mixtures are in contact with the catalyst; the overall reaction is the sum of the first equation, 3 times the second equation, 2 times the last equation. Without considering the state of water, NH 3 + 2 O 2 ⟶ H 2 O + HNO 3 Nitrogen & Phosphorus, Purdue University Drake, G.

Stafford and Lovell rebellion

The Stafford and Lovell rebellion was the first armed uprising against King Henry VII after he won the crown at the Battle of Bosworth in 1485. The uprising was led by Francis Lovell, Viscount Lovell along with Sir Humphrey Stafford and Thomas Stafford, brothers from Grafton, Worcestershire; the uprising occurred during Eastertime 1486. After the Battle of Bosworth in 1485, Francis Lord Lovell and Humphrey Stafford sought sanctuary at Colchester Abbey; the conspirators hoped to restore the Yorkist monarchy. Henry VII used spies to monitor the activities of known Yorkist supporters. Sometime in April 1486, King Henry learned that Lovell and Humphrey Stafford had escaped and were planning a rebellion. Sir Richard Edgcumbe and Sir William Tyler were appointed by the King to apprehend Lovell. With the failure of the plot, Lovell first joined fellow rebels at Furness Falls and fled to Margaret of York in Flanders. In the meantime the Stafford brothers had risen in rebellion in Worcester, despite the fact that King Henry had mass support in that area.

During this time Henry was in York on a nationwide tour of the country. As soon as he advanced towards Worcester in order to eliminate Yorkist support, on 11 May 1486 the Stafford brothers again fled to sanctuary, this time at Culham Abbey. King Henry had the Staffords forcibly removed from the abbey on the night of 14 May by John Barrowman and one follower, they were tried before the Court of King's Bench, where the justices ruled that sanctuary was not applicable in cases of treason. Henry ordered the execution of Humphrey Stafford of Grafton, but pardoned the younger Thomas Stafford; the arrest prompted a series of protests to Pope Innocent VIII over the breaking of sanctuary.

The Stand In (Seinfeld)

"The Stand In" is the 80th episode of the NBC sitcom Seinfeld. This was the 16th episode of the fifth season, it aired on February 24, 1994. In this episode, Jerry struggles to get a hospitalized friend to laugh, George persists in dating a woman he doesn't like to avoid being perceived as unable to commit, Kramer encourages his friend Mickey Abbott to wear lifts in order to keep his job as a stand-in. Riding on a bus and George meet a friend, Al Netche, who tells them another friend, Fulton, is in the hospital, has asked Jerry to visit him as he "needs a good laugh." Jerry visits Fulton and tells a story about a guy named "Pachyderm" juggling hot pizza slices, but Fulton never laughs. George has nothing to talk about with his girlfriend and wants to break up. Daphne tells George that Al advised her to end the relationship as George doesn't commit and will end up hurting her. George postpones the breakup. Kramer has a job as a stand-in in the series All My Children, along with his friend Mickey Abbott, a little person.

Mickey is worried about keeping his job as the young actor he stands in for is growing. Kramer suggests Mickey use lifts to increase his height. Mickey reluctantly agrees. Jerry sets up a date for Elaine with Phil Totola; the date is ruined. When he bumps into Phil at the hospital, Jerry drops hints that such exposure is offensive, but they go over Phil's head. Mickey plans to a little woman. Johnny Bigiano, another dwarf stand-in who envies Mickey, breaks into Mickey's locker and finds the lifts. Mickey is ostracized by the other dwarfs; as Tammy leaves with Johnny, Mickey angrily attacks Kramer. Jerry feels added pressure to be funny after his visit to the hospital coincides with a deterioration in Fulton's condition, he offers to do his act with new material. Jerry is so funny. To George's relief, Daphne says that she met another person: Jerry Persach, nicknamed "Pachyderm.” Larry David got the idea for the Mickey Abbott plot when he noticed how many little people worked as stand-ins for child actors.

Michael Richards recalled being excited by his work with Danny Woodburn, the actor who plays Mickey, due to the chemistry between their two characters. In the scene where Mickey attacks a seated Kramer, Richards wore a back brace and padding so that he could take a full fall without injury. A man exposing his penis on a date was drawn from a real date staff writer. David Sims of The A. V. Club gave the episode a B grade saying: " is not a great episode considering Larry David wrote it, but it's got some impressive touches, Phil Totola's dick move is one of them".
