How are gypsum and selenite chemically similar?
Gypsum and selenite are chemically similar as they both are forms of calcium sulfate with the same chemical formula (CaSO4·2H2O). They have the same crystal structure but differ in their crystal habits - gypsum typically forms as massive white rocks, whereas selenite forms clear and prismatic crystals.
What mineral will not scratch glass?

Chemical name for BrO4 and SeO32?

What are the largest crystals on earth?
The largest crystals on Earth are found in the Cave of the Crystals in Naica, Mexico. These selenite crystals can reach sizes of up to 39 feet (12 meters) in length and weigh several tons. They formed under unique conditions of high temperature and high mineral concentrations in the cave.
What are four types of crystals found in caves?
Calcite, selenite, and that's normally about it apart from perhaps some other metallic minerals if the cave is an area affected by mineralisation. They are not for collection though, except in serious scientific study, but to be left undisturbed for other cavers to enjoy seeing.
How is selenite formed?
Selenite is formed through the evaporation of water with high concentrations of calcium and sulfate ions. Over time, these ions combine and crystallize to form selenite structures, typically in underground caves or as mineral deposits in sedimentary environments. Temperature, pressure, and the presence of other minerals can also influence the formation of selenite.
Is sodium selenite an acid or base?
Sodium selenite is a salt formed by the combination of sodium hydroxide (a base) and selenous acid (an acid). Overall, it is considered to be a neutral compound.
What is the geological processes that formed the crystals in naica mine?
The selenite crystals were formed by hydrothermal fluids emanating from the magma chambers below.
What type of rock is selenite?

What does sodium selenite do in feed?
Sodium selenite is an inorganic form of selenium. Selenium is needed in a dog's diet. At the time sodium selenite was approved for use in dog foods, it was not known that it poses a high risk for dogs. Unfortunately, its use has not been stopped, but there are dog foods that do not have sodium selenite added to them. In order to avoid feeding your dogs dog food that contains sodium selenite, read the ingredients on the package. Sodium selenite should not be listed, though if grains are listed the food may contain some levels of sodium selenite that is present in the grains, depending on what soil the gran was grown in.
