1) Calcium Oxalate (CaC 2 O 4 ) crystal kidney stones are most common.  A few other types  are Sturvite ((NH 4 )MgPO 4 ∙6(H 2 O)), Uric acid (C 5 H 4 N 4 O 3 ), Calcium Phosphate  (Ca 3 (PO 4 ) 2 ), and Cystine ((SCH 2 CH(NH 2 )CO 2 H) 2 ). 2) Many of chemicals off of the given list of chemicals will combine to yield a precipitate.  Anything that contains Cl - , NH 4 + , or NO 3 -  will likely not yield a precipitate.  Carbonates,  phosphates, and oxalates are not very soluble and will very likely yield a precipitate. 3) Calcium Oxalate: Na 2 C 2 O 4  (aq) + CaCl 2  (aq)   CaC 2 O 4  (s) + 2NaCl (aq) Ca 2+  (aq) + C 2 O 4 2-  (aq)  CaC 2 O 4  (s) Sturvite:       Mg(NO 3 ) 2  (aq) + NH 4 (NO 3 ) 2  (aq) + Na 3 PO 4  (aq)   (NH 4 )MgPO 4  (s) + Na(NO 3 ) (aq) + (NO 3 ) -  (aq) Mg 2+  (aq) + NH 4 +  (aq) + PO 4 3-  (aq)   (NH 4 )MgPO 4  (s) Brushite:    CaCl 2  (aq) + Na 2 HPO 4  (aq)   CaHPO 4  (s) + 2NaCl (aq) Ca 2+  (aq) + HPO 4 2-  (aq)   CaHPO
