Question

What else can the copper react with? Note the type of reaction you expect for reactants Cu and O

Answer 1

Copper can react with oxygen to form copper oxide in a redox reaction. It can also react with silver ions to reduce them to elemental silver.

Step-by-step explanation:

Copper can react with a variety of elements. One example is the reaction with oxygen, where copper and oxygen combine to form a compound called copper oxide. This reaction is an example of a redox reaction, where copper acts as a reducing agent by reducing the oxygen. Another example is the reaction between copper and silver ions, where copper reduces the silver ions to elemental silver. This reaction can be observed by placing copper wire in a silver salt solution.

Answer 2

Copper reacts with oxygen in a synthesis reaction to form copper oxide, undergoes redox reactions with solutions like silver nitrate, and participates in single displacement reactions such as with zinc and copper(II) chloride.

Step-by-step explanation:

Copper can react with a variety of substances, including oxygen, acids like nitric acid, and solutions containing other metal ions. For example, when copper reacts with oxygen, the type of reaction is a synthesis reaction, forming copper oxide. When copper is placed in a solution of silver nitrate, a redox reaction occurs where copper reduces the silver ions to elemental silver while it is oxidized to copper ions. Zinc can also displace copper from copper(II) chloride in a single displacement reaction. Oxygen is known to react with metals and nonmetals forming different types of oxides. However, in the context of copper, it reacts at elevated temperatures to form black copper oxide. Other reactions include copper reacting with nitric acid to produce copper nitrate and nitrogen dioxide or with an aqueous solution of copper sulfate to displace the copper and form iron(II) sulfate in the case of iron.
