Vanadium can lose 1 to 5 electrons to give possible positive charges 1, 2, 3, 4, or 5. A previous worker in your lab gave you a vial labelled "Vanadium fluoride", but did not include the chemical formula on the label and did not indicate the charge of the vanadium ion. {Always be complete when you label things!!} The label does indicate that the formula mass is 126.94g/mol. What is the charge of the vanadium in this "vanadium fluoride"

What term is missing from the central region that describes hypotheses, theories, and laws? popular predictable mathematical falsifiable

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
