An iron ore sample was dissolved in hydrochloric acid and the iron was obtained as Fe2+(aq). The iron solution was titrated with 39.65 mL of 0.494 M Ce4+ solution according to the balanced chemical reaction shown below.Ce4+(aq) + Fe2+(aq) → Ce3+(aq) + Fe3+(aq)Calculate the mass of iron in the original ore sample. Please round your answer to the hundredths place.
Though illegal in many states,there are people who do it.However,it may confuse your computer,since you would loose the oxygen sensors on that corner.
Get the exhaust from a car with the factory dualsno one will complain about that.
buy to universal cat. converters at your local auto-zone. go to a local muffler shop. 1. cut everything off from the exhaust manifold back. 2. run tail pipe from manifold back about 3 ft. (both sides) 3. weld on cat. converters (both sides) 4. weld on another few feet on tail pipe (both sides) 5. weld on mufflers(both sides) glass pack's are cheapest 6. weld on another section on pipe (both sides) ready to cruise all legel
