Aluminium hydroxide
C2 , h5 , oh
Iron, oxygen, hydrogen Fe(OH)2 and Fe(OH)3
Talc chemical formula is Mg3Si4O10(OH)2.
OH is not an element. It consists of two separate elements: hydrogen (H) and oxygen (O).
The formula for hydroxide is (OH) however, hydroxide leaves an electron un-paired and bonds with another element or elements.
Aluminium hydroxide
slack lime consists of calcium(Ca) and hydroxide ion(OH ).It's formula is Ca(OH)2.
Calcium hydroxide contain calcium, hydrogen and oxygen.
Calcium hydroxide has molecular formula Ca(OH)2, so its elements are Calcium, Oxygen and Hydrogen.
Rust consists of hydrated iron oxides Fe2O3·nH2O and iron oxide-hydroxide (FeO(OH), Fe(OH)3).
DARK,EARTH,FIRE,LIGHT,WATER AND WIND
