Read the following passage and answer the questions followed by is silicates are a group of minerals which have the general formula SiO_(2), the most common of which is quartz. Quartz is a frame work silicate with SiO_(4), tetrahydra arranged in spirals. The spirals can turn in clockwise or anticlock wise direction a feature that results in there being two mirror images opticlaly active varities of quartz. The silicate anion in the mineral kinoite is a chain of three SiO_(4), tetrahedra that share coners with adjacent tetrahedra. The mineral also contain Ca^(2+),Cu^(2+) ions and water molecules in 1 : 1 : 1 ratio. The mineral is represented as
