Is an wedge shattering a slab of shale a physical or chemical change?
The wedge shattering the slab of shale is a physical change. This is because the shale undergoes a change in shape and size without any new substances being formed.
What property of a mineral is determined by its chemical composition?
The color of a mineral sample is determined by its chemical composition
What is energy stored in a substance because of its composition?
Chemical energy is the energy stored in a substance due to its chemical composition. This energy is released when chemical reactions occur.
What is the chemical composition of tin?
Tin is a chemical element with the symbol Sn and atomic number 50. Its chemical composition is typically just the element tin itself.
Does fluorite have a definite chemical composition?
Yes, fluorite has a definite chemical composition: it is a calcium fluoride mineral with the chemical formula CaF2.
What is shales chemical symbol?
It doesn't have one. Shale is a mixture and doesn't always have the same composition. Only elements have chemical symbols
What is the chemical formula for shale?
Shale is a rock not a chemical compound.
What is the chemical formula of shale?
The chemical formula of shale is variable, as it is a sedimentary rock composed mainly of clay minerals, quartz, and other minerals. The general formula can be written as (Al,Si)3O10(OH)2, representing the presence of aluminosilicate clay minerals in shale.
Is shale a chemical rock?
No, shale is clastic.
What is the chemical formula of shale rock?
The chemical formula for shale rock is variable, as it is composed of different minerals such as clay minerals (e.g., kaolinite, illite), quartz, feldspar, and various other components. Overall, shale is primarily composed of silicon, oxygen, aluminum, and other elements depending on its specific composition.
What happens when shale is soaked in vinegar?
When shale is soaked in vinegar, the acetic acid in the vinegar reacts with the calcium carbonate and other minerals present in the shale, leading to a chemical reaction that can dissolve some of these components. This can result in the weakening of the shale structure and the release of certain ions into the solution. Over time, the vinegar may also help to remove some of the organic materials or contaminants present on the shale's surface. However, the overall impact depends on the specific mineral composition of the shale.
What is the bulk modulus of shale?
The bulk modulus of shale typically ranges from 15 to 30 GPa, depending on factors such as composition and porosity.
What causes shale to change into slate?
Shale changes into slate through a process called metamorphism, which involves heat, pressure, and chemical changes. The heat and pressure cause the minerals in the shale to recrystallize into a denser, more compact form, resulting in the fine-grained texture and foliation characteristic of slate. The composition of the original shale, as well as the intensity and duration of the metamorphic conditions, influence the final characteristics of the slate.
What is the average seismic velocity of shale?
The average seismic velocity of shale typically ranges from 2 to 4 kilometers per second (km/s) depending on the composition and porosity of the shale formation.
When water evaporates its chemical composition?
The chemical composition remain unchanged.
How are slate and shale alike?
Dark Colour, Clay mineral composition (Kaolanite), Laminations of minerals
Is shale formed by physical or chemical weathering?
Shale is a clastic sedimentary rock formed of clay and silt sized eroded particles that are a result of both physical and chemical weathering. The clay minerals, however are the result of chemical weathering of feldspars.
