Consider the single chain silicate in figure (page 88). complete single chain crystals are built by bonding many of these chains together. how is that done? select one: a. covalent bonds form between the chains b. lonic bonds form between the chains o c. the chains bond to each other through the unbounded oxygens in the chains d. metallic bonds from between the chains e. the chains are held together by bonds to cations (like ca, mg, fe, or ai) between the chains - the cations bond to the unbounded oxygens in the silicate chains the silica tetrahedron (complex anion) is not electrically neutral - each oxygen is only half satisfied by the silicon atom at the center. what does this allow to happen? select one: a. it allows silica tetrahedrons to link together to form chains or sheets, or to bond with cations like ca, na, fe, or mg. b. it makes the silica tetrahedron weaker than other kinds of minerals c. it makes silica tetrahedrons more susceptible to chemical reactions that break down silicates d. all of the above why is color sometimes not a good way to identify minerals? select one: a. some minerals come in many colors b. color depends on grain size c. some minerals are metallic d. none of the above
