Answer:
D. Error is in sentence 1. The beam was a cathode ray.
Explanation:
Legit just looked up his experiments and it said right off the bat he studied cathode rays not gamma.
<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).
It must be freezing or condensation
