D: variation, There are two scenarios presented: V Two objects move toward each other and then attract. 0.3803 mol = 37.1 g c) How many grams of the excess reactant will remain after the reaction is over? Since the amount of product in grams is not required, only the molar mass of the reactants is needed. The chemical equation is already balanced. 6. Compound states [like (s) (aq) or (g)] are not required. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. 97.445 ZnS 8 moles Zns 1 mole Zn g Zn remaining Zn = 95.2 - 70.7173 = 24.4827 g Zn 105.4 gZnS x 1mole ZnS x 1mole S8 x 256.52 g S8 . 1. Therefore the ratio between cationic and anionic radii in zinc blend is 0.39 (74pm/190 pm) .This suggests a tetrahedral ion arrangement and four nearest neighbors from standard crystal structure prediction tables.
