One contributor to the destruction of the ozone layer in the upper atmosphere is the reaction with jet fuel from high flying aircraft. The reaction occurs in the following two step pathway: Step 1: O3 + NO --> NO2 + O2 Step 2: NO2 + O --> NO + O2 The nitrogen dioxide is considered to be a(n)

The nitrogen dioxide is considered to be an intermediate.

Explanation:

The nitrogen dioxide is considered to be an intermediate.

The reaction occurs in the following two step pathway:

Step 1: ..[1]

Step 2: ..[2]

Over all reaction :

[1] + [2] :

The nitrogen dioxide is considered to be an intermediate because its serving as a product in reaction occurring in step 1 and reactant in in reaction occurring in step 2. Also it do not appear in overall reaction of the process.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
