Which of the following is called argentite?
In mineralogy, argentite (from the Latin argentum, silver) is cubic silver sulfide (Ag2S), which can only exist at temperatures above 173 °C, 177 °C or 179 °C.
What does the ore argentite contain?
Argentite, a silver sulfide mineral, is an important constituent of silver ore deposits. It contains 87% silver, and forms blackish-gray coatings or masses with a metallic luster and a shining black STREAK. Characteristic is the ease with which it is cut.
Which metal is extracted from argentite?
Silver metal
Silver metal is extracted from its argentite ore by the method of.

What is the ore of argentite?
What is the chemical formula for kaolinite?
Al2O3 2SiO2
Kaolinite is a clay mineral of chemical formula Al2O3 2SiO2·2H2O that has a structure of 1:1 uncharged dioctahedral layer where each layer consists of single silica tetrahedral sheet and single alumina octahedral sheet [123,124].
What is the empirical formula for the mass of MG?
The empirical formula is the simplest whole-number ratio of atoms in a compound. The ratio of atoms is the same as the ratio of moles. So our job is to calculate the molar ratio of #”Mg”# to #”O”#. #”Mass of Mg = 0.297 g”#.
How do you find the empirical formula of magnesium oxide?
Measure the mass of the crucible and contents again. Calculate the mass of the magnesium oxide by subtracting the mass of the empty crucible. To work out the empirical formula, you need the mass of the magnesium (from step 2) and the mass of the oxygen atoms as well.
What is argentite named after the Latin word for silver?
Argentite is named for argentum, which is the Latin word used for silver. Black. Streak shiny. Acanthite crystallizes in the monoclinic system, and Argentite crystallizes in the isometric system.
Can argentite exist at normal temperatures?
As explained below in more detail, Argentite cannot exist at normal temperatures. Specimens labeled as Argentite are sometimes sold by dealers, however, these specimens are really Acanthite pseudomorph s after Argentite. Acanthite is named for the Greek term akantha, which means “thorn”, in allusion to it pointy crystal forms.
