What mineral is nonsilicate and cleaves when it breaks and has a salty taste?
The mineral you are describing is halite, commonly known as rock salt. Halite is a nonsilicate mineral that exhibits perfect cubic cleavage when it breaks. It has a characteristic salty taste, which is due to its sodium chloride composition. This mineral is often found in evaporite deposits formed by the evaporation of seawater.
What are the angles at which cleavage surfaces meet in halite?
In halite, which is the mineral form of sodium chloride (NaCl), cleavage surfaces meet at angles of 90 degrees. This characteristic cubic cleavage results from the mineral's isometric crystal system, where the internal atomic arrangement allows for easy breakage along specific planes. As a result, halite typically exhibits well-defined cubic crystals with sharp edges and corners.
What is an hypothesis for mineral identification?
A hypothesis for mineral identification could be that specific physical and chemical properties, such as hardness, color, luster, and crystal structure, can be used to accurately classify minerals into distinct categories. For example, "If a mineral exhibits a Mohs hardness of 7, a vitreous luster, and a cubic crystal habit, then it is likely to be identified as quartz." This hypothesis can be tested by examining various minerals and comparing their properties to known standards.
Is azurite metallic?
No, azurite is not metallic. It is a copper carbonate mineral that typically exhibits a bright blue color due to its chemical composition.
What mineral has striations?
Quartz is a mineral that commonly exhibits striations on its surface. These are often caused by growth patterns during its formation, giving it a lined or grooved appearance.
What is the mineral that is softer than calcite has a metallic luster and has cubic cleavage?
Pyrite is a mineral that is softer than calcite, has a metallic luster, and exhibits cubic cleavage.
A mineral that breaks into jagged pieces exhibits this property?
A mineral that breaks into jagged pieces exhibits fracture.
An unidentified mineral that is softer than calcite that exhibits a metallic luster and cubic cleavage?
The mineral might be pyrite, which has a hardness lower than calcite, a metallic luster, and cubic cleavage. Pyrite's hardness is around 6-6.5 on the Mohs scale, compared to calcite's 3. It forms cubic crystals and has a brassy color.
What mineral is nonsilicate and cleaves when it breaks and has a salty taste?
The mineral you are describing is halite, commonly known as rock salt. Halite is a nonsilicate mineral that exhibits perfect cubic cleavage when it breaks. It has a characteristic salty taste, which is due to its sodium chloride composition. This mineral is often found in evaporite deposits formed by the evaporation of seawater.
What is a mineral that breaks along one or more straight lines exhibits which?
That is cleavage.
What are the angles at which cleavage surfaces meet in halite?
In halite, which is the mineral form of sodium chloride (NaCl), cleavage surfaces meet at angles of 90 degrees. This characteristic cubic cleavage results from the mineral's isometric crystal system, where the internal atomic arrangement allows for easy breakage along specific planes. As a result, halite typically exhibits well-defined cubic crystals with sharp edges and corners.
What is the cubic shape of a mineral is a result of?
The shape of a mineral depends on the chemical structure that the bonds form between atoms in the mineral. A cubic mineral (such as pyrite) has a chemical structure that, as bonds are made, a cubic shape is formed.
What is cleavage of Galena?
Cleavage of galena is the tendency of the mineral to break along planes of weakness, resulting in smooth, flat surfaces. Galena exhibits perfect cleavage in three directions at right angles to each other, producing cubic or octahedral shapes. This property is a result of the crystal structure of galena.
Is cubic zirconia a mineral?
Minerals are, by definition, naturally occurring. Since cubic zirconia is synthesized in a lab, it is not considered a mineral.
What is a mineral with the same crystal system as salt?
Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
Is calcite metallic?
No, calcite is not metallic. It is a mineral that exhibits a vitreous or pearly luster and is typically translucent to opaque. It is a non-metallic mineral.
Is azurite metallic?
No, azurite is not metallic. It is a copper carbonate mineral that typically exhibits a bright blue color due to its chemical composition.
