Question

Give the balanced equations for the following:
i) The reaction that takes place during lightning.
ii) In the atmosphere, oxygen is converted into ozone.
iii) The reaction involved in the formation of acid rain.

Answer 1

(i) Splitting of $O_2$ into individual oxygenation

$O=O\underrightarrow{Lightning}2\left[O\right]$

$\left[O\right]+O_2⟶O_3$ (Ozone)

(ii) Conversion of oxygen into Ozone

$O_2\underrightarrow{UV}O+O$

$O+O_2⟶O_3$ (Ozone)

(iii) Formation of Acid Rain

$S{O}_2\left(g\right)+H_{2}O\left(g\right)⟶H_{2}S{O}_3\left(aq\right)$

$SO\left(g\right)+H_{2}O\left(g\right)⟶H_{2}S{O}_4\left(aq\right)$

$NO\left(g\right)+H_{2}O\left(g\right)⟶HN{O}_2\left(aq\right)$

$N{O}_2\left(g\right)+H_{2}O\left(g\right)⟶HN{O}_3\left(aq\right)$
