The silicate ion in the mineral kinoite ...

The silicate ion in the mineral kinoite is a chain of three `SiO_(4)^(4-)` tetrahedral that share corners with adjacent tetrahedral. The mineral also contains `Ca^(2+)` ions, `Cu^(2+)` ions and water molecules in ` 1 : 1 : 1` ratio. The mineral is represented as

A

`CaCuSi_(3)O_(10).H_(2)O`

B

`CaCuSi_(3)O_(10).2H_(2)O`

C

`Ca_(2)Cu_(2)Si_(3)O_(10).2H_(2)O`

D

None of these

The name 'silica' covers an entire froup of minerals which have the general formula SiO_2 the most tetrahedra arratnged in spirals . The spirals can turn in a clockwise or anti-clockwise direction - a feature that results in these being two mirror images opticallyy active, varieties of quartz. The silicate anion in the mineral kinoite is a chain of three SiO_4^(-4) tetrahedra that share corners with the adacent tatrahdr . The mineral also contains Ca^(2)=0 ions , Cu^(2+) ions and water molecules in a 1: 1: 1 ratio . This mineral is represented as :
