Question

What happens when a mixture of cu2o and cu2s are heated

Answer 1

When a mixture of Cu2O and Cu2S is heated, they react together to give copper metal and sulphur dioxide gas. ... Copper glance,Cu2S, is roasted in the presence of air to get converted to Cu2O. Cu2O then reacts with non-oxidised Cu2S ore in the absence of air to form copper metal.

Answer 2

Copper and sulfur dioxide gas is produced by heating a combination of copper oxide [$Cu_{2} O$] and copper sulfide [$Cu_{2} S$].

When a combination of $Cu_{2} O$ and $Cu_{2} S$ is heated, what happens?

• When $Cu_{2} O$ and $Cu_{2} S$ are heated together, they combine to form copper metal and sulfur dioxide gas.
• This is one of the processes for converting less reactive copper sulfide ore to copper metal.

Chemical decomposition:

• The act or effect of breaking down a single chemical entity into two or more fragments is known as chemical decomposition.
• Chemical breakdown is sometimes thought of as the polar opposite of chemical synthesis.
