True becuase dew is coming out of the air which if you look at a glass of water it has condensation on it becuase it is hot
Ferrous sulfate (FeSO4) is obtained by the reaction of aqueous ferric sulfate with gaseous sulfur dioxide and water according to the equation below:
Aqueous ferric sulfate = 
Gaseous sulfur dioxide = 
Water = 
Aqueous sulfuric acid = 
Aqueous ferrous sulfate = 
Thus, the balance equation becomes:
+
+
