These compounds are iron oxides as FeO, Fe2O3, Fe3O4.
Rust.
Two iron chlorides are known: iron(II) chloride and iron(III) chloride, FeCl2 and FeCl3.
NO!!!! It is a COMPOUND. It is made up of two elements. viz. Iron(Fe) and oxygen(O).
It is not an element. It is an compound made of two elements: Iron and Oxygen, FeO.
Water is a compound. It has molecules consisting of two hydrogen atoms bonded to one oxygen atom. So it is made of 2 different elements - Hydrogen and oxygen -- to become H20. Hydrogen is made out of two atoms hence the subscript number 2.
Carbon dioxide (CO2) is a chemical compound.
Fe2O3
Rust is a compound of iron and oxygen.
Two iron chlorides are known: iron(II) chloride and iron(III) chloride, FeCl2 and FeCl3.
Ozone is the only compound which has only three atoms of oxygen.
YES
Ozone is a compound. It is made of three atoms of oxygen.
Oxygen cannot be broken into two atoms unless it is an oxygen compound of oxygen. Oxygen is an element, therefore made up of atoms, and therefore atoms cannot be broken down into more atoms.
Iron Sulfate is a compound, FeSO4, made of three different elements (Fe, S and 4 Oxygen atoms) bound together in a molecule (eg. it is a greenish, soluble salt).
Water is a compound. A molecule of water is made up of two hydrogen atoms and one oxygen atoms. Oxygen and hydrogen are both elements. Water is a compound. A molecule of water is made up of two hydrogen atoms and one oxygen atoms. Oxygen and hydrogen are both elements.
NO!!!! It is a COMPOUND. It is made up of two elements. viz. Iron(Fe) and oxygen(O).
Si2O3
Water is made of one oxygen atom and two hydrogen atoms per molecule
