Please show work, completely and neatly. Use a separate piece of paper. Apply rules for significant figures. Show units in work. Show conversions. Relevant chapters in our text are chapters 11 and 12. 1. An iron-rich species of the mineral garnet is almandine. Its chemical formula is Fe:AlzSi:012. (a) How many chemical elements make-up almandine? (b) How many atoms make up a single almandine? 2. Salt is a crystalline sodium-chloride (NaCl). (a) Why do sodium and chlorine atoms bond together to form salt? (b) What crystalline form (shape) do the bonded sodium and chlorine atoms make? 3. Pick an element which has an isotope of interest, or use in, science (there are many), and discuss its significance (a paragraph should suffice). 4. How much would a ball (sphere) of granite 12 inches in diameter weigh? (You'll need to find the density of granite. Assume the ball of granite is a perfect sphere, volume V = ar", where r is the radius.)
