Iron ions and neutral iron atoms have the same physical and chemical properties.

Question

Iron ions and neutral iron atoms have the same physical and chemical properties. True False A reaction that forms an insoluble salt from aqueous solutions is known as a precipitation reaction. True False Sometimes you see the terms (aq), (s), (l), or (g) in a balanced chemical equation. What do these terms mean? They indicate how reactive or dangerous the chemicals in the equation are. They indicate whether a reaction takes place. The indicate if the chemical is a strong or weak electrolyte. They specify the phases of the reactants and products in the equation. Can I use these same six spot test reagents to identify cobalt in a unknown sample? Yes, if you ran a cobalt nitrate standard and it yielded a different pattern of reactions or different colors than the other metals. Yes, provided it is in the 2+ oxidation state. Yes, it will give similar results to iron because cobalt and iron are next to each other m the periodic table. After you have completed your reactions, how should you dispose of the liquids in your well plate? in the orange bottles in the fume hood they should be returned to the reagent containers they should be washed down the sink with plenty of water
