Question

Heating mixture of \[C{u_2}O\] and \[C{u_2}S\] will give
(A) \[Cu + S{O_2}\]
(B) \[Cu + S{O_3}\]
(C) \[CuO + CuS\]
(D) \[C{u_2}O + S\]

Answer 1

Hint: In a chemical reaction reactants reaction with each other at appropriate conditions to give products. The speed of some reaction is fast and the speed of some reaction is slow. And slow reactions can be made fast by using specific catalysts.

Complete step by step answer:
Copper is a metal denoted by the symbol \[Cu\] and copper electropositive in nature it donates two electrons and oxygen is electronegative. It takes two electrons from copper metal and an ionic bond is formed between copper and oxygen. So to break this bond heat is supplied to it is an endothermic reaction. And the atomic mass of copper is \[63.5u\].
Copper is a metal denoted by symbol \[Cu\] and copper electropositive in nature it donates two electrons and sulphur is electronegative in nature takes two electrons from copper metal and an ionic bond is formed between copper and sulphur. So to break this bond heat is supplied.
Heating mixture of copper oxide \[C{u_2}O\]and copper sulphide\[C{u_2}S\]gives- Copper and sulphur dioxide gas.
\[2C{u_2}O + C{u_2}S\xrightarrow{{Heat}}6Cu + S{O_2}\]
This reaction is an example of an autoreduction process because copper metal reduces itself.

Hence, option A is the correct option.

Note:
-Copper metal is soft in nature due to this it is ductile in nature and so it is very used in industry. And the electrical conductivity and thermal conductivity of copper metal is very high. So it is used in making wires copper is used.
-Copper metal is solid in state at room temperature.
-Sulphur dioxide gas is colourless gas in nature and the odour of this gas like rotten egg. And sulphur dioxide is used as a strong oxidising agent. It can be liquefied very easily at low temperature and high pressure.
