IN Ellingham diagram formation of zinc oxide curve appears below the curve of carbon monoxide so zinc is a better reducing agent
Zinc is a transition element with general oxidation state as +2. It gets easily oxidised to its oxidation state of +2 by elements which are less reactive than zinc . For example: 2Zn + H2O --> Zn2O + H2
Metals are extracted from ores. An ore is a rock that contains enough of a mineral (metal compound) for the metal to be extracted from it. Most metals are extracted from an ore by reduction with carbon or by electrolysis.
what is product when zinc added to carbon dioxide?
If the reduction involves carbon getting oxidized, it would be... Zinc oxide + carbon -----------> Zinc + carbon monoxide that's ZnO + C ----------> Zn + CO or if the reduction involves carbon monoxide getting oxidized, it would be... Zinc oxide + carbon monoxide -----------------> Zinc + carbon dioxide that's ZnO + CO ----------> Zn + CO2
no.
Hey! I have the same class don't worry I found it out: Zinc is a stronger reducing agent than hydrogen and thus tends to reduce the hydrogen and force it out of the solution. Hope that Helps! :)
The only possible product would be zinc hydride. Zinc hydride is usually not prepared directly from zinc and hydrogen, but by using an even stronger reducing agent such as sodium hydride or lithium aluminum hydride. Zinc hydride is unstable and decomposes back to zinc and hydrogen over time.

Zinc (metal) does not react with gold (metal), neither with cyanide (salt).
Metals are extracted from ores. An ore is a rock that contains enough of a mineral (metal compound) for the metal to be extracted from it. Most metals are extracted from an ore by reduction with carbon or by electrolysis.
Magnesium is a more reactive metal therefore for using any extraction method you would have to use electrolysis, which is expensive. Whereas for zinc it is extracted from its ore chemically by reduction using carbon. When an ore is reduced you are taking the oxygen out of the metal, this is because carbon can only take the oxygen away from metals which are less reactive than carbon its self. For example, zinc oxide is reduced in a blast furnace to make zinc.
zinc is metal

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.
no.
to extract zinc from its mineral you can heat it with carbon
