The acidity of normal rain water is due to
a) so2
b) co2
c) no2
d) no

SO₂

Explanation:

Acid rain is due to SO₂.

SO₂ + ½ O₂ + H2O = H₂SO₄

H₂SO₄= 2H⁺ + SO₄²⁻

Harmful pollutant in the air such as sulfur dioxide creates acid rain. SO₂ reacts with water vapor and oxygen to form sulfuric acid, which makes the rain acidic. H₂SO₄ releases H⁺ which decreases the pH of rain water. At acidic pH rainwater is harmful to both living beings and architectural objects.

the answer is the first option

explanation:

just googled it m8. not that hard

lol

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
