Aum (or Om, ॐ) is the sacred symbol of Hinduism, and is prefixed and sometimes suffixed to all Hindu mantras and prayers. Because it represents God, the supreme reality in three aspects of Brahma, Vishnu and Shiva, it is the symbol of the Hindu Dharma. It contains a deep symbolic message of the divine primordial vibration of the Universe, representing all existence, encompassing all of nature into the One Ultimate Reality. This symbol is commonly found on necklaces worn by Hindus. In the Upanishads, it is defined as an affirmation, as in allowing or saying 'yes'.

1 AU = the average distance from the earth to the sun. I can't remember what that is, but if you find out, just multiply it by 40.

From en.wikipedia.org:\n\n"Gold does not react with most chemicals but is attacked by chlorine, fluorine, aqua regia and cyanide. Gold dissolves in Mercury. In particular, gold is insoluble in nitric acid, which will dissolve most other metals. Nitric acid has long been used to confirm the presence of gold in items."

The symbol above is a Pound from England.  The elaborate L stands for the abbreviation of lb. (libra - pound)\n\nThe Australian dollar (currency code AUD) has been, since 1966, the currency of the Commonwealth of Australia, including the Australian Antarctic Territory, Christmas Island, Cocos (Keeling) Islands, Heard Island and McDonald Islands and Norfolk Island, as well as the independent Pacific Island states of Kiribati, Nauru and Tuvalu. It is normally abbreviated with the dollar sign $ or alternatively A$ to distinguish it from other dollar-denominated currencies. It is sometimes affectionately called the "Aussie battler"—during a low period (relative to the US dollar) around 2001 and 2002 the currency was sometimes locally called the "Pacific Peso". It is divided into 100 cents. All previous issues of Australian coins and banknotes, including Pounds, shillings and pence are still legal tender.\n\nThe Australian dollar is currently the sixth-most-traded currency in world foreign exchange markets (behind the US dollar, the yen, the euro, the British pound and the Canadian dollar), accounting for approximately 4-5% of worldwide foreign exchange transactions. The Australian dollar is popular with currency traders due to the relative lack of government intervention in the foreign exchange market, the general stability of the economy and government as well as the prevailing view that it offers diversification benefits in a portfolio containing the major world currencies (especially because of its greater exposure to Asian economies and the commodities cycle).

Yup.  According to the electrochemical series, the Au3+ ion (in order to plate itself, gold must first be converted to an ion from an anode in an electrochemical cell: how that is so is another question...) is a relatively good oxidizing agent (which means itself gets reduced) when compared with other metals at least.  You can check this by seeing its standard reduction potential.  Standard reduction potential for gold is +1.50 eV while that of Fe(steel is mostly iron) is only ) 0.77eV.  The rule is that, the metal with the greater reduction potential gets plated on the one with less potential.\n\nCheck this link for a better understanding. http://en.wikipedia.org/wiki/Image:Srptable.JPG

Mercury is an elemental compound and has the chemical symbol Hg.  As such, you can not "chemically" make it.  The chief source of Mercury is from an ore called cinnbar (HgS)  You mine the ore -- Spain and Italy produce about 50% of the world's supply.

Elemental symbol is S. Atomic number is 16, and Mass number 32, which means it has 16 protons, 16 electrons and 16 neutron. It is in period 3 in the periodic table and group VI which puts it in the p-block. This means that it has 6 elctrons in its outer shell, and three electronic shells all together. It can be found in meteorites, hot springs and volcanoes, and Jupiters Moon Io is made up mainly of sulfur compounds. In it's pure form it is a pale yellow, odourless, brittle solid which is insoluble in water. It is vital to life as it is a minor (but essential) constituent of fats, body fluids and skeletal minerals. Sulfur dioxide in the atmosphere is one of the main causes of acid rain.\n\nHope that helped

No, it's Ag2S. The 2 is a subscript, denoting 2 Silver atoms to 1 Sulphur atom. Silver has a valency of 1+, while Sulpur has a valency of 2-, hence 2 Silver atoms are needed to balance with 1 Sulphur atom to form a compound. Besides, the equation would make sense then. 2 Silver atoms and 1 Sulphur atom on both sides of the equation, the equation is now balanced. 10 marks please, thank you!
