Carbon and hydrogen are the two main elements that make up crude oil.
About 2.57 ounces of cinnabar are required to yield one ounce of mercury because cinnabar is composed of approximately 96.3% mercury by weight.
Iron is, itself, and element. It is not a compound of two elements.
Hydrogen oxide consists of hydrogen and oxygen elements.
Silicon and oxygen are the two elements that make up silicates. They are the building blocks of the silica tetrahedron, which is the fundamental structure of silicate minerals.
Earth+Minerals=Cinnabar
No elements make time.
After a chemical reaction two elements form a chemical compound.

Iron is, itself, and element. It is not a compound of two elements.
Calcium (Ca) and oxygen (O) are the two elements that make up calcium oxide (CaO).
Cinnabar is not a pure substance because it is a mineral composed of mercury sulfide and may contain impurities or other elements mixed in its crystalline structure. This impurity affects the chemical composition of cinnabar, making it a mineral rather than a pure substance.
Cinnabar (with an "A" after the two "N") is made from the two elements Mercury (metal) and sulfur, however sulfur isn't a metal. It's symbol is HgS, and is actually an ore of mercury and is most often found near volcanic activity while it can also be found in alkaline geothermal springs.
NABR is composed of the elements sodium (Na), bromine (Br), and nitrogen (N).
Two elements, two hydrogen atoms and one oxygen atom
Two or more elements can combine into a compound.
