Hi,

#7259. Name the element, because it is highly reactive, it is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). With few exceptions, minerals containing the element are in the maximally oxidized state as inorganic phosphate rocks.

#7260. Name the village on the Swedish island of Resarö, in Vaxholm Municipality in the Stockholm archipelago. Today the residential area is dominated by suburban homes.

The name of the village translates to "outer village". It is perhaps most famous for being the single richest source of elemental discoveries in the world; the chemical elements yttrium (Y), ytterbium (Yb), erbium (Er) and terbium (Tb) are all named after it.

Re: General Quiz

Hi,

Borax bead

A small loop is made in the end of a platinum or nichrome wire and heated in a Bunsen burner flame until red hot. A stick made of another inert substance such as a magnesia stick (MgO) may also be used. It is then dipped into powdered borax and held in the hottest part of the flame where it swells up as it loses its water of crystallization and then shrinks, forming a colourless, transparent glass-like bead (a mixture of sodium metaborate and boric anhydride).

The bead is allowed to cool and than wetted and dipped into the sample to be tested such that only a tiny amount of the substance adheres to the bead. If too much substance is used, the bead will become dark and opaque. The bead and adhering substance is then heated in the lower, reducing, part of the flame, allowed to cool, and the colour observed. It is then heated in the upper, oxidizing, part of the flame, allowed to cool, and the colour observed again.

Characteristic coloured beads are produced with salts of copper, iron, chromium, manganese, cobalt and nickel. After the test, the bead is removed by heating it to fusion point, and plunging it into a vessel of water.

#7261. Name the color in Metal in Oxidizing flame and Reducing flame of Cobalt.

#7262. Name the color in Metal in Oxidizing flame and Reducing flame of Chromium.

Hi,

#7265. Name the  is the only tennis player (born 9 August 1938) to twice achieve a Grand Slam, in 1962 and 1969, and the latter remains the only time a man has done so in the Open Era. He also won eight Pro Slam titles, including the "pro Grand Slam" in 1967, and he contributed to five Davis Cup titles for Australia during an age when Davis Cup was deemed as significant as the four majors.

#7266. What is also referred to as the "Channel Slam" - still arguably the sport's biggest challenge?

Re: General Quiz

Hi,

#7267. What is the motto of Forbes magazine?

#7268. In 1922, DeWitt Wallace started the magazine while he was recovering from shrapnel wounds received in World War I. Wallace had the idea to gather a sampling of favorite articles on many subjects from various monthly magazines, sometimes condensing and rewriting them, and to combine them into one magazine.

The magazine's format for several decades consisted of 30 articles per issue (one per day), along with a vocabulary page, a page of "Amusing Anecdotes" and "Personal Glimpses", two features of funny stories entitled "Humor in Uniform" and "Life in these United States", and a lengthier article at the end, usually condensed from a published book.

Name the magazine.
