Ca(OH)2
Three structural isomers with the molecular formula C4H10O are butan-1-ol, butan-2-ol, and methoxyethane. Each of these isomers has a unique arrangement of atoms, resulting in different chemical and physical properties.
The subscript refers to the amount of atoms of that element in the formula e.g. H2O means two atoms of hydrogen and one atom of oxygen in one molecule of water. Hope this helps.
Certain rocks, such as arsenic-rich minerals like realgar, or minerals containing lead or mercury, can be poisonous if ingested or inhaled. It is important to exercise caution when handling these types of rocks and to avoid prolonged contact or ingestion to prevent potential harm.
