Answer:
the correct answer is number (1)
Explanation:
this number is the one who refers to the continental shelf because as you can see it refers to an area which is a shallow water area and near from the continent . and the continental shelf is exactly this area , it is defined as a continent which is under an area of a shallow water of the sea which we can called shelf sea
number 2 refers to continental slope and it defines as the steep slope which connect between the continental shelf and the sea floor
<h3><u>Answer;</u></h3>
N₂(g) + 2O₂(g) → 2NO₂(g).
<h3><u>Explanation;</u></h3>
- <em><u>Photo-chemical smog is a type of air pollution that results from the reaction of solar radiation with airborne pollutant mixtures of nitrogen oxides (NOx) and volatile organic compounds (hydrocarbons).</u></em>
- Formation of photochemical smog involves a couple of chemical reactions which includes;
<em>N2 + O2 → 2NO </em>
<em>2NO + O2 → 2NO2</em>
<em>NO2 → NO +O </em>
<em>O + O2 → O3 </em>
<em>O3 + NO ⇆ NO2 + O2 </em>
Combining all the reactions we obtain an overall reaction;
N₂(g) + 2O₂(g) → 2NO₂(g).
