1.	Read the following message passage and answer the followed by is silicates are a group of minerals which havegeneral 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 anticlork wise direction a feature that result in there being two mirror images optically active varities of quartz The following represents various silicate anions . Their formulae are respectively
Answer» `SiO_(3)^(2-), SiO_(7)^(2-)` `SiO_(4)^(4-), Si_(3) O_(10)^(8-)` `SiO_(4)^(2-), SI_(3)O_(9)^(2-)` `SiO_(3)^(4-), Si_(3)O_(7)^(8-)` Solution :`[SiO_(4)^(-4), Si_(3)O_(10)^(8-)]` [TETRAHEDRAL units]
