What else can I help you with?
What is composition of clay?
Clays are hydrous aluminum silicates with trace amounts of other elements like calcium, iron, and magnesium.
What is the mineral group to gypsum?
it's in the mineral group sulfate because gypsum is a hydrous calcium sulfate
What is an example of a hydrous salt?
An example of a hygroscopic salt would be calcium chloride, a salt that absorbs water from the atmosphere to form a saturated solution
What type of rock is alabaster?
Alabaster refers to varieties of two different minerals: gypsum (a hydrous sulfate of calcium) and calcite (a carbonate of calcium). Gypsum is the alabaster of the present day; calcite is generally the alabaster of the ancients
Is ulexite combustible?
No, ulexite is not combustible. It is a hydrous sodium calcium borate mineral that is typically used for its optical properties rather than as a fuel source.
Why the mineral of a metamorphic rock usually different from the protolith?
Remineralization can occur because of an exchange of fluids or because the squeezing out of fluids by pressure and heat create an environment where hydrous minerals cannot exist and are replaced with non-hydrous minerals.
What is the chemical name for baby powder?
It is made of a hydrous silicate material called talc, which has a chemical formula of Mg3Si4O10(OH)2. It is called talcum powder. (those are the only possible chemical names)
How does a metamorphic turn into a sedimentary rock?
By exposure to heat and/or pressure through depth of burial, directed pressure, or proximity to a magma source. Existing minerals can recrystallize, non-hydrous minerals can replace hydrous minerals, new minerals can be formed from the introduction of new ions from heated solutions, and minerals can become flattened and aligned in parallel layers.

What is the chemical name of talcum powder?
The chemical name of talcum powder is Hydrous Magnesium Silicate. It is one of the extensively used substances. It is also known as the softest mineral.
WHAT IS THE MEANING OF THE gypsum?
A mineral consisting of the hydrous sulphate of lime (calcium). When calcined, it forms plaster of Paris. Selenite is a transparent, crystalline variety; alabaster, a fine, white, massive variety.
