Heres What Happens If You Drop Francium in Water

Francium is element No. 87 on the periodic table. The element can be prepared by bombarding thorium with protons. An extremely small amount occurs naturally in uranium minerals, but it is so rare and radioactive that there has never been enough of it to actually see what would happen if a piece was dropped into water. However, scientists know for sure that the reaction would be energetic, possibly even explosive. ​ The piece of francium would blow apart, while  the  reaction with water would produce hydrogen gas, francium hydroxide, and a lot of heat. The entire area would be contaminated with radioactive material. Why Francium Reacts so Strongly The reason for the strong exothermic reaction  is because francium is an alkali metal. As you move down the first column of the periodic table, the reaction between the alkali metals and water becomes increasingly violent, as follows: A small amount of lithium will float on water and burn.Sodium burns more readily.Potassium breaks apart, burning with a violet flame.Rubidium ignites with a red flame.Cesium releases enough energy that even a small piece blows up in water.Francium is below cesium on the table and would react more readily and violently. This occurs because each of the alkali metals is characterized by having a single valence electron. This electron easily reacts with other atoms, such as those in water. As you move down the periodic table, the atoms become larger and the lone valence electron is easier to remove, making the element more reactive. In addition, francium is so radioactive that it is expected to release heat. Many chemical reactions are accelerated or enhanced by temperature. Francium would input the energy of its radioactive decay, which is expected to magnify the reaction with water.

Board of Education of Topeka, Kans., unanimously agreeing that segregation in public schools is unconstitutional. The ruling paves the way for large-scale desegregation. The decision overturns the 1896 Plessey v. Ferguson ruling that sanctioned separate but equal segregation of the races, ruling that separate educational facilities are inherently unequal. It is a victory for NAACP attorney Thurgood Marshall, who will later return to the Supreme Court as the nation s first black justice.

It was passed by the Senate on April 8, 1864, by the House on January 31, 1865, and adopted on December 6, 1865. On December 18, Secretary of State William H.

Mardi Gras (French, fat Tuesday), pre

Mardi Gras (French, fat Tuesday), pre-Lenten fes Essay Mardi Gras (French, fat Tuesday), pre-Lenten festival celebrated in Roman Catholic countries and communities. In a strict sense, Mardi Gras, or Shrove Tuesday, is celebrated by the French as the last of the three days of Shrovetide and is a time of preparation immediately before Ash Wednesday and the start of the fast of Lent. It is thus the last opportunity for merrymaking and indulgence in food and drink. In practice, Mardi Gras is generally celebrated for a full week before Lent. It is marked by spectacular parades featuring floats, pageants, elaborate costumes, masked balls, and dancing in the streets. Mardi Gras originated as one of the series of carnival days held in all Roman Catholic countries between Twelfth Night, or Epiphany, and Ash Wednesday; these carnivals had their origin in pre-Christian spring fertility rites. The most famous modern Mardi Gras festivities are those held in New Orleans, Louisiana; Rio de Janeiro, Brazil; Nice, France; and Cologne, Germany. Lent, period of fasting and penitence traditionally observed by Christians in preparation for Easter. The length of the Lenten fast, during which observants eat sparingly, was established in the 4th century as 40 days. In the Eastern churches, where both Saturdays and Sundays are regarded as festival days, the period of Lent is the eight weeks before Easter; in the Western churches, where only Sunday is regarded as a festival, the 40-day period begins on Ash Wednesday and extends, with the omission of Sundays, to the day before Easter. The observance of fasting or other forms of self-denial during Lent varies within Protestant and Anglican churches. These bodies emphasize penitence. The Roman Catholic church has in recent years relaxed its laws on fasting. According to an apostolic constitution issued by Pope Paul VI in February 1966, fasting and abstinence during Lent are obligatory only on Ash Wednesday and Good Friday. Each year more than 24 million visitors produce more than $4.7 billion for the Louisiana economy. The hub of this tourism industry is New Orleans. The quiet old-world charm of the French Quarter is periodically disturbed by celebrations at the time of Mardi Gras, the Sugar Bowl football game, and major events at the Superdome. The state is also noted for its Gulf and freshwater fishing and for its excellent hunting opportunities, as well as Thoroughbred and quarter-horse racing. Louisiana maintains a system of 26 parks and recreation areas.

Each role is dramatically important to the structure of the play, Alfieri acts as a bridge between the audience and events taking place in the play. The play is opened by a speech form Alfieri You can see how uneasily they nod to me. This is addressing the audience and immediately establishes a bridge between the audience and the play. He explains the cultural and social backgrounds of both the characters and Red Hook. He tells the way Sicilians were taught to take the law into their own hands and to do to them, as they have done to you, in other words, an eye for an eye. Alfieri describes how many brought this way of life from Sicily with them Frankie Yale himself was cut precisely in half by a machine-gun on the corner of Union Street, two blocks away and there were many shot by unjust men. Alfieri explains that things have calmed and the residents of Red Hook adapted to American society and the law and Alfieri prefers it this way. Alfieri hints that the events that are to come are inevitable sat there as powerless as I, and watched it run its bloody course.

Alfieri mentions that Eddie has a Destiny and that expands on the point that it is inevitable because destinies cannot change there was a future, there was a trouble that would not go away.
