Question: Uranium metal heated to 250 to 300 C (482 to 572 F) reacts with hydrogen to form uranium hydride. Even higher temperatures will reversibly remove the hydrogen. This property makes uranium hydrides convenient starting materials to create reactive uranium powder along with various uranium carbide, nitride, and halide compounds. Two crystal modifications of uranium hydride exist: an form that is obtained at low temperatures and a form that is created when the formation temperature is above 250 C.
Try to answer this question if possible: At what temperature range in degrees Fahrenheit won't uranium metal form uranium hydride?
Answer: unanswerable
Question: Similar alloys with the addition of a small amount of lead can be cold-rolled into sheets. An alloy of 96% zinc and 4% aluminium is used to make stamping dies for low production run applications for which ferrous metal dies would be too expensive. In building facades, roofs or other applications in which zinc is used as sheet metal and for methods such as deep drawing, roll forming or bending, zinc alloys with titanium and copper are used. Unalloyed zinc is too brittle for these kinds of manufacturing processes.
Try to answer this question if possible: Why isn't unalloyed zinc used in construction applications?
Answer: too brittle
Question: After finishing the first draft and returning it to Lippincott, the manuscript, at that point titled "Go Set a Watchman", fell into the hands of Therese von Hohoff Torrey known professionally as Tay Hohoff a small, wiry veteran editor in her late 50s. Hohoff was impressed. "[T]he spark of the true writer flashed in every line," she would later recount in a corporate history of Lippincott. But as Hohoff saw it, the manuscript was by no means fit for publication. It was, as she described it, "more a series of anecdotes than a fully conceived novel." During the next couple of years, she led Lee from one draft to the next until the book finally achieved its finished form and was retitled To Kill a Mockingbird.
Try to answer this question if possible: What was the name of the editor who helped Lee finish her book?
Answer: Therese von Hohoff Torrey
Question: There are scouting and guiding groups on Saint Helena and Ascension Island. Scouting was established on Saint Helena island in 1912. Lord and Lady Baden-Powell visited the Scouts on Saint Helena on the return from their 1937 tour of Africa. The visit is described in Lord Baden-Powell's book entitled African Adventures.
Try to answer this question if possible: When was Scouting established on Saint Helena?
Answer:
1912
