carbon
When a substance reacts with oxygen, it forms an oxide. For example, iron reacting with oxygen forms iron oxide (rust), sulfur reacting with oxygen forms sulfur dioxide, and carbon reacting with oxygen forms carbon dioxide.
Reacting with another elements oxygen forms oxides.
6H2 + 6O2 ---> 6H2O + 3O2 This reaction leave excess unreacted oxygen behind.
u get O3 and thats what makes up our ozone layer
The bonds that connect hydrogen molecules to oxygen molecules in water are covalent bonds. In a water molecule, each hydrogen atom forms a covalent bond with the oxygen atom by sharing electrons.
Rust is the result of iron reacting with oxygen in the presence of water or moisture, leading to the formation of iron oxide. Sulfur can sometimes accelerate the corrosion process by forming sulfuric acid when combined with water, but it is not the direct cause of rust on iron.
carbon CH4
3 bonds are commonly formed by nitrogen and 2 are commonly formed by oxygen.
The formula for ozone reacting to form oxygen is O3+O= 2O2
When sodium reacts, it forms sodium oxide (Na2O) by reacting with oxygen from the air. This reaction involves one atom of sodium reacting with one molecule of oxygen to produce two atoms of sodium and one molecule of oxygen combined as sodium oxide.
When a metal is burned, it can form metal oxides by reacting with oxygen in the air. For example, when iron is burned, it forms iron oxide (rust).
Metals react with air in a form called oxidizing. This is caused because the oxygen molecules are reacting with the surface of the metal.
