Current Question (ID: 17839)

Question:

$\text{Acid rain occurs due to the oxidation of:}$ $1.\ \text{Carbon, sulphur (unsaturated hydrocarbon) and nitrogen.}$ $2.\ \text{Ethanol.}$ $3.\ \text{Methanol.}$ $4.\ \text{Methane.}$

Options:

1. $\text{Carbon, sulphur (unsaturated hydrocarbon) and nitrogen.}$
2. $\text{Ethanol.}$
3. $\text{Methanol.}$
4. $\text{Methane.}$

Solution:

$\text{Acid rain is due to oxides of carbon, sulphur (unsaturated hydrocarbon) and nitrogen.}$ $\text{Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms.}$ $\text{Acid rain is caused by emissions of sulphur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.}$ $2\text{SO}_2(s) + \text{O}_2(g) + 2\text{H}_2\text{O}(l) \rightarrow 2\text{H}_2\text{SO}_4(aq)$ $4\text{NO}_2(g) + \text{O}_2(g) + 2\text{H}_2\text{O}(l) \rightarrow 4\text{HNO}_3(aq)$
