Determine percentage by weight of HNO 3 in the original sample of concentrated nitric acid. Omit formulas for any ionic or molecular species that do not take part in the reaction. You need not balance. In all cases a reaction occurs. Excess concentrated sodium hydroxide solution is added to solid aluminum hydroxide.
Propanol is burned completely in air.
The first ionization energy of aluminum is lower than the first ionization energy of magnesium. In a separate experiment, a concentrated solution of sodium chloride, NaCl, was electrolyzed also using inert platinum electrodes. In each experiment, gas formation was observed at both electrodes. Clearly indicate which half-reaction occurs at each electrode. Clearly indicate which half-reaction occurs at each electrode.
