How does copper react to gasoline?
Copper lines should not be used because fuel polymerizes (thickens) in copper tubing during long periods of disuse and can clog fuel injectors. … The molecular structure of the copper or galvanized lines or tanks reacts with the acid and contaminates the fuel.
Is copper sulfate a gas?
Copper(II) sulfate is a hydrated, blue solid – it is attached to water molecules. This becomes whitish when anhydrous – when it is not molecularly bound to water.
Why are refrigerator copper ac pipes icing up?

Is zinc more reactive than copper?
Explanation: Elements differ in relative reactivity, it is something often taught in schools as “the reactivity series”.
