Nitrogen dioxide (NO2) reacts with OH in the atmosphere to form nitric acid (HNO3). Nitric acid can also form when nitrogen dioxide (NO2) reacts with the nitrate radical (NO3) in the presence of atmospheric water

Why is nitric acid (HNO3) important?

Please see this link.


How many atoms are there in the formula HNO3 (Nitric acid)?

One. One hydrogen, one nitrogen, and 3 oxygen (notice the 3 in subscript after the O).


What gasses make up acid rain?

Most of what is termed as Acid Rain contains Sulphuric Acid, this is formed by a combination of Hydrogen Sulphide, Sulphur Dioxide and water. Answer: Acid precipitation is formed when sulfur oxides (SOx) and nitrogen oxides (NOx) are absorbed by water droplets. This forms sulfurous/sulfuric and nitrous/nitric acids. Some of the sulfurous acid can be transformed into sulfuric acid. The chemistry:Sulfur dioxide and water form sulfurous acid (H2SO3)SO2(g) + H2O(l) H2SO3(aq) In some cases sulfur dioxide (SO2) oxidizes to sulfur trioxide (SO3)2SO2(g) + O2(g) -> 2SO3(g) The sulfur trioxide (SO3) then combines with water making sulfuric acid (H2SO4)SO3(g) + H2O(l) -> H2SO4(aq) Some oxides of nitrogen like nitrogen dioxide (NO2) react with water to form nitrous acid (HNO2) and nitric acid (HNO3)2NO2(g) + H2O(l) -> HNO2(aq) + HNO3(aq)


What observations can be made when dilute nitric acid is added to lead carbonate?

The lead carbonate is dissolved in nitric acid and carbon dioxide is released.


When silver nitrate reacts to hydrochloric acid what type of reaction takes place?

When silver nitrate (AgNO3(aq)) reacts with hydrochloric acid (HCl(aq)), a chemical reaction takes place:AgNO3(aq) + HCl(aq) ---> AgCl(s) + HNO3(aq)This is specifically called a double replacement reaction. Silver nitrate and hydrochloric acid react to create silver chloride and nitric acid.A precipitation reaction (double displacement reaction):AgNO3 + HCl = AgCl + HNO3
