Question

Write a balanced chemical equation when (ii) Mixture of cuprous oxide and cuprous sulfide is heated.

Answer 1

Chemical Reactions:

• When two or more molecules combine to create a new product, the process is known as a chemical reaction.
• Reactants are substances that interact to make new substances, whereas products are those substances that result from the interaction.

Balanced Reactions:

• An equation for a chemical reaction is said to be balanced if both the reactants and the products have the same number of atoms and the total charge for each component of the reaction.
• In other words, both sides of the reaction have an equal balance of mass and charge.

In case, when the mixture of Cuprous oxide/ cuprous sulfide mixture is heated:

• Copper metal is formed as a byproduct when a mixture of cuprous oxide and cuprous sulfide is heated, along with the development of ${\mathrm{SO}}_2$ gas.

$$\begin{gathered} 2{\mathrm{Cu}}_2\mathrm{O}\left(\mathrm{aq}\right)+{\mathrm{Cu}}_2\mathrm{S}\left(\mathrm{s}\right)\to 6\mathrm{Cu}\left(\mathrm{s}\right)+{\mathrm{SO}}_2\left(\mathrm{g}\right) \\ \mathrm{Cuprous}\mathrm{Cuprous}\mathrm{Copper}\mathrm{Sulphur} \\ \mathrm{Oxide}\mathrm{Sulphide}\mathrm{Dioxide} \end{gathered}$$
