Question

What is 3 acetyl-2-methyl-4-phenyl-4,5-dihydrofuran 2,4-dinitrophenylhydrazine?

Answer 1

Rust is the result of corroding steel after the iron (Fe) particles have been exposed to oxygen and moisture (e.g., humidity, vapor, immersion). When steel is exposed to water, the iron particles are lost to the water's acidic electrolytes. ... Oxygen causes these electrons to rise up and form hydroxyl ions (OH).
