What is the basic structural unit of silicate minerals? And draw the structure
Explain how the structure of silicate minerals ultimately affects how different types of tectonic plates form and interact.

Which of the following minerals is an example of one single silicate tetrahedron? a. augite b. olivine c. biotite d. quartz
Consider the structure of caffeine (re-draw it here), and answer the following questions from a structural perspective. Caffeine is an alkaloid and, as such, is weakly basic. Circle and label the basic atom or atoms (hints: consider the base in Experiment 4C, and consult the Derivative procedure on page 235). Identify (circle on your structure) and discuss two different structural features that would account for solubility in methylene chloride (hint: think intermolecular forces). Identify (circle on your structure) and discuss...
1) Draw the full structural formula, the condensed structural formula, and the line structure of each of the following molecules: butane 1-butene Full structural formula Condensed structural formula Line structure 2) What is the molecular formula of the molecule whose structure is shown below? 3) What are isomers?
2. Draw the structure for caffeine. What part of caffeine is basic?
2) Chemical analyses of silicate minerals are given as weight percent oxides, to ensure that charges of cations and anions are balanced. It’s important to be able to interconvert mineral chemical formula and chemical analyses (see Klein pp. 99-104). Analysis of an olivine yields (all as weight percent): 36.63% SiO2, 30.96% MgO, 32.41% FeO; express this composition in terms of mole % forsterite (i.e., Fox, find x). You will need to calculate the formula weights of FeO and MgO. Please...
