Chemistry Matter and Change
When 9.59 g of a certain vanadium oxide is heated in the presence of hydrogen, water and a new oxide of vanadium are formed. This new vanadium oxide has a mass of 8.76 g. When the second vanadium oxide undergoes additional heating in the presence of hydrogen, 5.38 g of vanadium metal forms.
a. Determine the empirical formulas for the two vanadium oxides.
b. Write balanced equations for the steps of the reaction.
c. Determine the mass of hydrogen needed to complete the steps of this reaction.
