Hello, sorry I think I was a bit bland with the question. In the periodic descriptions attached below, how did you come to the conclusion that the letters equalled the elements in the chart?- Which clue helped you figure that out for each element. (Provide a small explanation of how you came to the conclusion using the given properties.) Also, how does the Hydride, Chloride, and Oxide tell about the element? How is that helping us when finding the element?

I Review I Constants I Periodic Table On Greg's last visit to his doctor, he complained of feeling tired. His doctor orders a blood test for iron. Sandra, the registered nurse, does a venipuncture and withdraws 8.0 mL of blood. About 70% of the iron in the body is used to form hemoglobin, which is a protein in the red blood cells that carries oxygen to the cells of the body. About 30% is stored in ferritin, bone marrow, and the liver. When the iron level is low, a person may have fatigue and decreased immunity. Enter an equality for one tablet of the iron supplement. Express the mass in milligrams to two significant figures. Previous Answers The normal range for serum iron in men is 80 to 160 mcg/dL. Greg's iron test showed a blood serum iron level of 42 mcg/dL, which indicates that Greg has iron deficiency anemia. His doctor orders an iron supplement to be taken twice daily (b.i.d.). One tablet of the iron supplement contains 110 mg of iron. Part B Choose two conversion factors for…
