Question

which metal have least possible chances of getting corrode and why?or complete reaction for following with their types of reaction a.) zinc +silver nitrate= b.)zinc carbonate on heating gives=?​

Answer 1

Answer:

a)zinc + silver nitrate=zinc nitrate+ silver

Displacement reaction

b)zinc carbonate --->zinc oxide+co2(on heating)

decomposition reaction

Explanation:

because silver is least reactive in the reactivity series so (a) has least chances to corrode.

Answer 2

Hey mate here's your answer hope you find it helpful..

Gold is the metal which have least chances of getting corroded as it does not react with oxygen, moisture present in air..

OR

Zn+AgNo3=>Zn(No3)2 (displacement reaction as a more reactive metal displaces a less reactive metal from it's salt sol.)

Heat

ZnCo3=========>ZnO+Co2 ( decomposition reaction as a single reactant breaks down into two or more products)..

ZnO+C==>Zn+Co2
