A. Reaction with what gas in the atmosphere makes natural rain water slightly acidic? (2 points) B. Describe the chemical reactions that occur to change sulfur to sulfuric acid. (2 points)
C. How much more acidic is acid rain water with a pH of 2 than unpolluted rainwater with a pH of 6? Use your knowledge of pH (not the information provided in this article) and show your work. (2 points)

See explanation

Explanation:

On the pH scale acidity ranges from pH values of 0-6.9. Natural rain water is slightly acidic due to the presence of carbon dioxide in the atmosphere which is an anhydride of carbonic acid.

CO2(g) + H2O(l) > H2CO3(aq)

B. The equations that turn sulfur to sulfuric acid are;

S(l) + O2(g) > SO2(g)

2SO2(l) + O2(g) > 2SO3(g)

SO3(g) + H2SO4(l) > H2S2O7(l)

H2S2O7(l) + H2O(l) > 2H2SO4(l)

-

At pH 6, H^+ concentration = 1 * 10^-6 M

At pH 2, H^+ concentration = 1 * 10^-2 M

Hence;

1 * 10^-2/1 * 10^-6

= 10^4 times more acidic

the answer is b & c i believe : )

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
