Multiple-choice questions may continue on the next column or page find all choices before answering. 001 2.0 points What is the main objective of the synthetic procedure that you are going to carry out in the laboratory? 1. The main objective is to complete the experiment in less than 90 minutes. 2. The main objective is to convert toxic reagents into a more environmentally safe form for disposal. 3. The main objective is to make obser- vations and then develop a theory that will explain our observations. 4. The main objective is to compare a syn- thetic procedure with a natural procedure. 5. The main objective is to create a crystal sample for subsequent analysis. correct 6. The main objective is to verify that den- sity is an intensive property. Explanation: The main objective of any chemical synthe- sis procedure is to create the desired chemical product. 002 2.0 points You will begin your synthetic procedure by reacting ammonium iron (II) sulfate hexahy- drate, Fe(NH 4 ) 2 (SO 4 ) 2 6H 2 O, with oxalic acid, H 2 C 2 O 4 .
