Sulfuric acid will react with which of the following to form sulfur dioxide gas Select one: a. Sodium sulfite b. Thioacetamide c. Sodium sulfate d. Oxygen Clear my choice

Sodium sulfite (Na2SO3)

Explanation:

Sulfuric acid is able to displace volatile acids from their corresponding salts and the acids displaced are unstable and they break down to give volatile products

For example, in to reaction of sulfuric acid and sodium sulfite; two processes occur

1. Sulfuric acid forms sodium sulfate and sulfurous acid

Na2SO3(s) + H2SO4(aq) > Na2SO4(aq) + H2SO3

2. The H2SO3 is unstable thereby decompose spontaneously to water and sulfur dioxide gas.

H2SO3 > H2O(l) + SO2(g)

Final reaction gives;

Na2SO3(s) + H2SO4 (aq) > Na2SO4(aq) + H2O(l) + SO2(g)

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

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.
