Given that up to four ammonia (nh3) molecules can form a complex with one zinc ion (zn2+), what equation would you employ to calculate the fraction of free zinc ion (zn2+) when dissolved in water that also contains a large stoichiometric excess of dissolved ammonia ? show only the equation with all terms specified explicitly, no calculations.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
