No, its a compound which is 2 or more elements combined. Copper oxide is copper + oxygen which are 2 separate substances.
Neither. Copper is not a mixture at all. It is a pure element.
No. Copper used in wiring would not qualify as laboratory-grade (pure). It would be far too expensive to manufacture and would not improve the conductivity enough to make a difference. Some copper wire is even plated. Laboratory-grade (pure) copper is a single substance, the element copper.
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
No, Salt is a compound of Sodium and Chlorine. A pure substance consists of only one type of element.
Heating copper oxide with carbon (in the form of coal or charcoal) causes a reduction reaction, where carbon removes oxygen from copper oxide to produce carbon dioxide and leave behind pure copper. This process is known as a reduction reaction, where carbon acts as a reducing agent to extract copper from its oxide form.
Copper is a pure substance.
Yes, copper is an element, which is a pure substance.
Yes. Calcium oxide is a compound which is a type of pure substance.
Copper wire is a pure substance, as it is made entirely of copper atoms.
copper oxide...
Copper metal is an element and thus a pure substance.
Copper metal is an element and thus a pure substance.
Oxide is not an element . Copper plus oxygen eaquals copper oxide .Pure copper exposed to oxygen turns greenish .
Homogeneous
Copper metal is an element and thus a pure substance.
Copper sulfate is a pure substance.
Copper(I) chloride is a pure substance.
