oxygen is 1 but i don't know the other 1 sorry
There are a few products that can be used to build a firewood storage rack. Some of these materials are two by four wooden boards, Allan blocks, and rust resistant screws.
Rust is a chemical change and indicates a reaction do to the dramatic color change. It is the result of an oxide. So, there are NO substances needed for steel to rust. Even though steel itself is an alloy. :P However, you do need one element: OXYGEN!==========================Answer #2:Rust is iron oxide. In order for it to form,iron and oxygen must be present. Iron isan essential component of steel.
For example the cause of sliding friction of two materials is when the stress between the Materials is not equal to zero
yes, the moisture in the air will cause rust to form on brake rotors, bare metal and moisture causes rust, nothing to worry about, the rust will go away when you drive it and will return when your vehicle sits for any length of time
Rust is a compound of iron and oxygen.
two weeks til rust two weeks til rust
Any type of material has friction because everything has microscopic hills and valleys; some materials have more friction because the materials hills and valleys are larger than other materials.
it will cause a chemical reaction between the two materials
The two colors that make rust are light/dark brown with some orange
Taking two or more drugs at the same time will usually cause an interaction of some type.
almost all the rust resistant materials like wheel whims , huge machinery and the most important some times our utensils too . they are so made due to contact with water which cause rusting in several metals . therefore alloys such as tungsten chromium etc. are used.
A composite material is a type of artificial material. This artificial material is usually made of two different materials usually held together by cement.
