What are three major contents of meteorites?
Silicates, oxides, and sulfides.
Do silicates react with acids as carbonates do?
Silicates generally do not react with acids like carbonates do. Silicates are generally insoluble in common acids due to their strong chemical bonds, whereas carbonates typically react with acids to form carbon dioxide gas, water, and a salt.
How do sheet silicates differ from framework silicates?
Sheet silicates have a layered structure where silica tetrahedra are arranged in sheets with cations between the layers, while framework silicates have a three-dimensional network of silica tetrahedra connected in all directions. Sheet silicates have weaker bonds between layers, allowing for easier cleavage and flexibility, while framework silicates have stronger bonds, resulting in a more rigid structure.
What most common mineral group is broken into the subgroups of ferromagnesian and non ferromagnesian?
The most common mineral group that is broken into the subgroups of ferromagnesian and non-ferromagnesian is the silicate mineral group. Ferromagnesian silicates contain iron and/or magnesium, while non-ferromagnesian silicates do not contain these elements. Examples of ferromagnesian silicates include olivine and pyroxene, while examples of non-ferromagnesian silicates include feldspar and quartz.
What is the second most common group of minerals?
Silicates are the second most common group of minerals, after the group of minerals known as the carbonates. Silicates are composed of oxygen and silicon atoms, and they make up the majority of the Earth's crust.
Describe the six main crystalline structures of silicate minerals?
Isolated tetrahedra silicates do not link with other silicon or oxygen atoms Ring Silicates form by sharing oxygen atoms Single Chain Silicates form a chain when sharing oxygen atoms Double Chain Silicates form when two or more single chains of tetrahedra bond to each other Sheet Silicates form when each tetrahedron shares three of its oxygen atoms with other tetrahedra Framework Silicates form when each tetrahedron is bonded to four other tetrahedras :)
How do sheet silicates differ from network silicates?
Sheet silicates and network silicates differ primarily in their structural arrangements. Sheet silicates, such as micas and clays, consist of layered structures where silicate tetrahedra are arranged in two-dimensional sheets, allowing for easy cleavage and flexibility. In contrast, network silicates, like quartz and feldspar, have a three-dimensional framework where tetrahedra are interconnected in all directions, resulting in a more rigid structure. This difference in bonding and arrangement affects their physical properties, such as cleavage, hardness, and overall stability.
