Question

The silicate anion in the mineral kinetic is a chain of three SiO₄^4– tetrahedral that shares conners with adjacent tetrahedral. The mineral also contains Ca icon Cu ions and water molecules in a 1:1:1 ratio mineral represented as :

CaCu₂Si₃O₁₀⋅H₂O

CaCuSi₃O₁₀⋅H₂O

Ca₂Cu₂Si₃O₁₀⋅2H₂O

None of these

Given :
Ca,CH and H₂O molecule in the ratio 1:1:1

Hence, among the given options. B is rejected.

Ca₂Cu₂Si₃O₁₀.2H₂O shares corner with next and 80 on and so it forms linear structure with (SiO₃)^–²ⁿ ions.

Therefore, three units will have total negative charge of eight and positive charge will be the same.

Hence, the mineral is Ca₂Cu₂Si₃O₁₀.2H₂O. *(SiO₃)n^–²ⁿ:

Therefore, "the correct answer is option C."
