Lightning equation of Nitrogen Why can NO be produced during lightning? |
N2(g) + O2(g) -> 2NO Nitrogen atoms are bonded to each other by triple covalent bonds. Very difficult to break apart and require high temperatures |
|
|
Automobile engines equation Nitric acid equation Effects of acid rain |
NO(g) + 1/2 O2 (g) -> NO2 (g) 2NO2 (g) + H2O (l) + 1/2 O2 (g) -> 2HNO3 Acidifies lakes and kills fish and water plants. Destroys buildings, monuments of marble |

|
SO2 (g), SO3(g) Oxidation of SO2 SO3 and acid rain equation |
SO2(g) + 1/2 O2(g) -> SO3 SO2 (g) + NO2(g) (CATALYST) -> SO3 (g) + NO (g) How is NO2 regenerated? NO (g) + 1/2 O2(g) -> NO2(g) SO3 + H2O -> H2SO4 |
