Question: Uranium metal reacts with almost all non-metal elements (with an exception of the noble gases) and their compounds, with reactivity increasing with temperature. Hydrochloric and nitric acids dissolve uranium, but non-oxidizing acids other than hydrochloric acid attack the element very slowly. When finely divided, it can react with cold water; in air, uranium metal becomes coated with a dark layer of uranium oxide. Uranium in ores is extracted chemically and converted into uranium dioxide or other chemical forms usable in industry.
Try to answer this question if possible: What is a notable form uranium ore is converted into after extraction?
Answer: uranium dioxide
Question: Most legal theorists believe that the rule of law has purely formal characteristics, meaning that the law must be publicly declared, with prospective application, and possess the characteristics of generality, equality, and certainty, but there are no requirements with regard to the content of the law. Others, including a few legal theorists, believe that the rule of law necessarily entails protection of individual rights. Within legal theory, these two approaches to the rule of law are seen as the two basic alternatives, respectively labelled the formal and substantive approaches. Still, there are other views as well. Some believe that democracy is part of the rule of law.
Try to answer this question if possible: According to some, what is the rule of law is formed to protect?
Answer: individual rights
Question: From the 1930s through much of the 1960s, Florida was essentially a one-party state dominated by white conservative Democrats, who together with other Democrats of the Solid South, exercised considerable control in Congress. They gained federal money from national programs; like other southern states, Florida residents have received more federal monies than they pay in taxes: the state is a net beneficiary. Since the 1970s, the conservative white majority of voters in the state has largely shifted from the Democratic to the Republican Party. It has continued to support Republican presidential candidates through the 20th century, except in 1976 and 1996, when the Democratic nominee was from the South. They have had "the luxury of voting for presidential candidates who pledge to cut taxes and halt the expansion of government while knowing that their congressional delegations will continue to protect federal spending."
Try to answer this question if possible: Does Florida benefit from taxes
Answer: Florida residents have received more federal monies than they pay in taxes: the state is a net beneficiary
Question: Matte solder is usually fused to provide a better bonding surface or stripped to bare copper. Treatments, such as benzimidazolethiol, prevent surface oxidation of bare copper. The places to which components will be mounted are typically plated, because untreated bare copper oxidizes quickly, and therefore is not readily solderable. Traditionally, any exposed copper was coated with solder by hot air solder levelling (HASL). The HASL finish prevents oxidation from the underlying copper, thereby guaranteeing a solderable surface. This solder was a tin-lead alloy, however new solder compounds are now used to achieve compliance with the RoHS directive in the EU and US, which restricts the use of lead. One of these lead-free compounds is SN100CL, made up of 99.3% tin, 0.7% copper, 0.05% nickel, and a nominal of 60ppm germanium.
Try to answer this question if possible: What's the process by which bare copper gets covered in solder?
Answer:
hot air solder levelling
