Welcome to FSMT. Thank you for downloading and using our APP, our developers will continue to optimize the user interface, aiming to improve the user experience.
The effects of sulfide are widely used in chemistry, biology, environment and so on. It is necessary to learn about common metallic and nonmetallic sulfides.
The APP focuses on sulfides and sulfates with the aim of understanding and learning their molecular formula, CAS number, atomic mass and special properties and properties. Users can doodle characters by "imitating" them. This is a way to learn the molecular formula of sulfides and to understand their physical and chemical properties.
