Copper was first used by man over 10,000 years ago. A copper pendant discovered in what is now northern Iraq has been dated about 8700 B.C. For nearly five millennia copper was the only metal known to man, and thus had all the metal applications.

The origin of the metal mirrors is linked with the Parthasarathy Temple of Aranmula. According to the local legends, the local king had brought 8 families of bronze smiths from Tamil Nadu in connection with the renovation work of the Parthasarathy Temple centuries ago. + Follow Source: aranmulakannadi.org

Chemical Properties of Nonmetals. Non-metals have a tendency to gain or share electrons with other atoms. They are electronegative in character. Nonmetals, when reacting with metals, tend to gain electrons (typically attaining noble gas electron configuration) and become anions: \[\ce{3Br2(l) + 2Al(s) \rightarrow 2AlBr3(s)} onumber \]

Solution Hydrogen gas is usually liberated when an acid reacts with a metal. Take few pieces of zinc granules and add 5 ml of dilute H2SO4 and shake it. The gas produced is passed into a soap solution. The bubbles of soap solution are formed. These soap bubbles contain hydrogen gas. The reaction occurs as follows: H2SO4(aq)+Zn (s)→ ZnSO4(aq)+H2(↑)

Explanation: a) zinc metal is added to copper sulphate solution. When zinc is added to copper sulphate solution due to more reactivity of zinc, copper is replaced by zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless. → (Zinc) (Copper sulphate) (Zinc sulphate) (Copper)

JEE State Boards Byju's Answer Reaction of HCl with Metals Metal compound A reacts with dilute Hydrochloric acid to produce effervescence. The gas evolved extinguishes a burning candle. Write a balanced chemical equation for the reaction if one of the compounds formed is Calcium chloride. Understanding the chemical reaction:

Solution. Verified by Toppr. Usually, hydrogen gas is liberated when an acid reacts with a metal. Eg. zinc + sulphuric acid → zinc sulphate + hydrogen. Zn+H 2SO 4→ZnSO 4→+H 2(gas) Was this answer helpful?

In general, electrolytic refining is a process of purification of impure metal during which an electric current is passed through an electrolytic cell which contains impure metal as anode, a suitable electrolyte and pure metal as cathode.

An electrolytic reduction process known as smelting dissolves the alumina in a cryolite bath inside carbon-lined cells, or pots. A powerful electric current, which is passed through the bath, separates aluminum metal from the chemical solution and the metal is siphoned off.
