What is the word equation for zinc oxide plus magnesium?

Zinc oxide reacts with metallic magnesium to produce magnesium oxide and metallic zinc.


How do you separate copper from copper oxide?

I think you mean how do you extract copper from copper oxide, if so here's your answer. Take your copper oxide and heat it with something that is more reactive than copper. Carbon is a good example. The more reactive carbon will oxidise, taking the oxygen from the copper oxide leaving copper. copper oxide + carbon --> copper + carbon dioxide 2Cu0 + C --> 2Cu + CO2


What happens if you combine zinc oxide and copper?

Reaction of Zinc with Copper(I) oxide (cuprous oxide, Cu2O), a red powder; 2 Zn + Cu2O →2 Zn O + 2 Cu and Reaction of Zinc with Copper(II) oxide (cupric oxide, CuO), a black powder; Zn + CuO →Zn O + Cu Reason :- The most reactive metals (for example Zn) can displace any of the metals (for example Cu) which are lower in the reactivity series; the higher metal reduce the ions of the lower metal.

What salt is produced from zinc oxide plus hydrochloric acid?

Zinc chloride is produced when zinc oxide reacts with hydrochloric acid.


Is zinc plus cupric sulfate equals zinc sulfate plus copper a single displacement reaction?

Yes, the reaction between zinc and copper sulfate is a single displacement reaction. In this reaction, zinc displaces copper from copper sulfate to form zinc sulfate and copper. The more reactive zinc replaces the less reactive copper in the compound.

Why does sodium oxide plus zinc give sodium zincate plus hydrogen?

It doesn't. There is no source of hydrogen atoms in the equation, and there is no zincate. Sodium oxide plus zinc produces zinc oxide plus sodium. Na2O + Zn ---> ZnO + 2Na

What does zinc plus oxygen equals?

Zinc is a metal and Oxygen is a non-metal.


What type of reaction is this 2ZnO plus C gives 2Zn plus CO2?

This is an oxidation-reduction reaction. The carbon reduces the zinc oxide to zinc and the zinc oxide oxidises the carbon to carbon dioxide. It can also be called a displacement reaction, as the carbon displaces the zinc from its oxide.

Compounds composing of metal and oxygen?

A compound containing a metal plus oxygen would be a metal oxide. For example: Sodium plus oxygen would produce Sodium oxide, Bismuth and Oxygen would produce Bismuth oxide, Zinc plus Oxyen would produce Zinc oxide and so on.


How do you separate copper oxide from a mixture of copper oxide and zinc oxide?

wel u put the mixture in a glass cup and pour vinegar and salt and surgar into it. mix it around by putting ur hand on top of the glass and shake.the apply 2 pints of water and shake it. then watch as they separate!!!!!!!!!! its cool. trust me=)


What is zink plus oxygen make?

When zinc reacts with oxygen, it forms zinc oxide. This chemical reaction is a synthesis reaction where zinc combines with oxygen to produce zinc oxide as a product.
