Answer 2

Explanation:

• Reddish brown color flakes on iron utensils or tools are due to reaction between the iron and oxygen present in an air.

$4Fe+3O_2\rightarrow 2Fe_2O_3$

• Copper reacts with oxygen gas to form copper oxide.

$4Cu+O_2\rightarrow 2Cu_2O_$

• Black tarnish on silver is due to hydrogen sulfide and oxygen.

$4Ag+2H_2S+O_2\rightarrow 2Ag_2S+2H_2O$
