The vanadium in a sample of ore is converted to VO2. The VO2 ion is subsequently titrated with MnO4 in acidic solution to form V(OH)4 and manganese(II) ion. To titrate the solution, 26.45 mL of 0.02250 M MnO4 was required. If the mass percent of vanadium in the ore was 58.1%, what was the mass of the ore sample? Which of the four transition metal ions in this titration has the highest oxidation state?
When heavy oils are cracked in a catalytic or thermal cracking process, lighter hydrocarbon compounds are formed. Most cracking processes on heavy oil feeds form products with carbon numbers ranging from two to greater than twenty.
