Stardew Valley is a farming simulation game primarily inspired by Story of Seasons, a series by Marvelous and previously known as Harvest Moon. [1] At the start of the game, players create a character, who inherits a plot of land and a small house once owned by their grandfather in a small village called Pelican Town, located in the titular ...
The Official Stardew Valley Cookbook consists of 74 recipes from Stardew Valley, and these selections are divided into seasons. [1] Based on in-game food, the book offers options ranging from farmed foods to foraged mushrooms, berries, and fresh fish. [2]
Iridium compounds are used as catalysts in the Cativa process for carbonylation of methanol to produce acetic acid. [92] [93] Iridium complexes are often active for asymmetric hydrogenation both by traditional hydrogenation. [94] and transfer hydrogenation. [95] This property is the basis of the industrial route to the chiral herbicide (S ...
Metallic iridium is found with platinum and other platinum group metals in alluvial deposits. [23] Naturally occurring iridium alloys include osmiridium and iridosmine, both of which are mixtures of iridium and osmium. It is recovered commercially as a by-product from nickel mining and processing. [20]
Iridium is the most corrosion-resistant metal known as it is not attacked by acids, including aqua regia. In the presence of oxygen, it reacts with cyanide salts. Traditional oxidants also react, including the halogens and oxygen at higher temperatures. Iridium also reacts directly with sulfur at atmospheric pressure to yield iridium disulfide.
Another oxide, iridium tetroxide, is also known, with iridium in the +8 oxiation state. [7] This compound was formed by photochemical rearrangement of [(η 1-O 2)IrO 2] in solid argon at a temperature of 6 K (−267.15 °C; −448.87 °F). At higher temperatures, the oxide is unstable. [8] The detection of the iridium tetroxide cation IrO +
Iridium is part of WikiProject Rocks and minerals, an attempt at creating a standardized, informative, comprehensive and easy-to-use rocks and minerals resource. If you would like to participate, you can choose to edit this article, or visit the project page for more information.
Iridium(IV) oxide, IrO 2, is the only well-characterised oxide of iridium. It is a blue-black solid. It is a blue-black solid. The compound adopts the TiO 2 rutile structure , featuring six coordinate iridium and three coordinate oxygen.
