Question

airborne pollutants are highly corrosive to metal, including residue from factory smoke and acid rain. a. true b. false

Explanation:

Airborne pollutants like factory smoke residue and acid rain contain substances (e.g., sulfur - containing compounds in acid rain) that can react with metals. For example, acid rain (which has a low pH due to dissolved acidic gases) can corrode metals through chemical reactions such as oxidation - reduction reactions. Factory smoke may contain particulate matter with reactive chemicals that also contribute to metal corrosion.

Answer:

A. True
