A student noticed that the magnesium ribbon appeared to be oxidized-the metal surface was black and dull rather than silver and shiny. What effect would the oxidized magnesium ribbon have on the measured volume of hydrogen gas? Woulc the calculated molar volume of hydrogen be too high or too low as a result of this error? Explain.
