The first plagioclase crystals to form as a hot melt cools are high in?
The first plagioclase crystals to form as a hot melt cools are high in calcium content. These calcium-rich plagioclase crystals are known as anorthite and are typically found in the early stages of crystallization in igneous rocks.
Permanent hardness of water due to?
Permanent hardness of water is typically caused by the presence of calcium sulfate (CaSO4) and magnesium sulfate (MgSO4) in the water. These minerals do not precipitate out of solution when water is boiled, unlike temporary hardness caused by calcium bicarbonate which can be easily removed by boiling. Permanent hardness can be removed through processes like ion exchange or chemical precipitation.
Is there calcium in cement?
Yes,Sorel in 1867 announced the discovery of an excellent cement formed from the combination of magnesium oxide and magnesium chloride solution. This cement type is known by many different names, such as Sorel, magnesite and magnesium oxychloride cement. This cement has many superior properties to Portland cement. However, there are two other known magnesia cements. The first is magnesium oxysulfate (MOS), which is the sulfate analogue of magnesium oxychloride and is formed by the combination of magnesium oxide and magnesium sulfate solution. The second is magnesium phosphate cement (MAP), formed by the reaction between magnesium oxide and a soluble phosphate, such as ammonium phosphate monobasic (NH4H2PO4)
How does calcium first ionization energy compare to the first ionization energy of magnesium and potassium?
Calcium's first ionization energy is lower than that of magnesium but higher than that of potassium. This is due to the increasing atomic size down the group, which decreases the effective nuclear charge felt by the outermost electron. Magnesium, being higher in the group, has a smaller atomic radius and a stronger attraction between the nucleus and its valence electron, resulting in a higher ionization energy. Conversely, potassium, being further down the group, has an even larger atomic radius, leading to a lower ionization energy than calcium.
When magma cools minerals with higher melting points will?
crystallize first because they will solidify at higher temperatures. This process is called fractional crystallization and leads to the formation of different minerals with varying compositions and textures in the cooling magma.
What minerals are absorbed in the gastrointestinal tract without being digested first?
Minerals such as calcium, iron, and magnesium are absorbed in the gastrointestinal tract without being digested first.

Origin name for magnesium?
The name magnesium comes from the Greek word "magnesia," which refers to the district in Thessaly where magnesium minerals were first discovered.

Alphabatically which is the first and last of the Alkaline Earth Metals?
Barium Beryllium Calcium Magnesium Radium Strontium
Is there a fertilizer or soil amendment for calcium and magnesium deficient soils?
Yes, dolomitic lime treats calcium and magnesium deficient soils. But first do a soil test to find out the exact pH. The pH determines the application rate of your treatment. Then follow the container's instructions exactly.
Which is metal out of the first twenty elements?
Lithium, Beryllium, Sodium, Magnesium, Aluminium, potassium & calcium.... Boron is a metalloid.
When magma cools minerals with higher melting points will crystallized first or second?
Minerals with higher melting points will crystallize first as the magma cools because they will solidify at higher temperatures. This process is known as fractional crystallization and helps explain the formation of different mineral layers in a cooling magma chamber.
What are the first five alkali earth metals?
Beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), and barium (Ba).
Who discovered magnesuim?
Sir Humphry Davy first isolated magnesium in its pure form.Even before that many compounds and minerals of magnesium were known to man and were used.Best example is epsum salt.
What elements has the highest first ionization energy out of strontium magnesium beryllium calcium?
Beryllium will have the highest. Down a group ionization energy decreases.
What is the first minerals tends to form by Bowen's Series?
Bowens' Reaction Series measures the melting points of various silicate minerals, with the ones with highest melting points at the top. So as a completely moltenmagma containing all these minerals cools down, the first to crystallise are:ABOUT 1400 CELSIUSOlivinePyroxene (e.g. augite)Amphibole (e.g. hornblende)Biotite micaOrthoclase feldsparMuscovite micaSilica (e.g. quartz).ABOUT 800 CELSIUSNotice I've deliberately left out plagioclase feldspar because plagioclases of different composition crystallise out at different temperatures. Calcium-rich plagioclase crystallises out at about the same temperature as olivine (mineral 1), but sodium-rich plagioclase crystallises out about the same temperature as biotite mica (mineral 4). All plagioclase crystallises out at a higher temperature than orthoclase (mineral 5).So in answer to your question the first minerals to form as a magma cools are olivine and calcium-rich plagioclase feldspar, at around 1400 Celsius.
