Rusting is a chemical reaction.
Rust is of 2 types . Rust on iron is part of chemistry while rust on cereal crops is part of Fungi or Biology .
The question is a little vague, but rust could be categorised under chemistry as rust is a chemical reaction between oxygen (O2) and water (H2O)
Physical properties- such as it's color, weight, etc. Chemical properties- such as ability to rust, flammability, etc.
Its iron being converted into iron oxide (rust) by oxidation. That's chemistry.
What cleaning product will remove rust stains best.
There is a dangerous chemical called dihydrogen oxide that causes people to perspire and cars to rust. Very very bad chemistry for earth! Dihydrogen Oxide Must be banned !!!!
Chemistry developed from the observations of natural processes, in which substances were mixed, dissolved, heated, or cooled. Natural processes include rust, solubility, fermentation, crystallization, and alloying (mixtures of metals). (For more on how chemistry developed, see the related link)
They DO know something about inorganic chemistry.
What cleaning product will remove rust stains best
To determine a reacting substance that use in manufacture of machines buildings ex iron get rust etc
Based purely on the knowledge of chemistry, rust forms faster in the heat. Rust is the oxidation of iron and this reaction will occur at a faster rate at a higher temperature as the molecules are provided with more kinetic energy. However, the rate of 'rusting' also depends on humidity etc.
