What is a chemical reaction that can explain acid rain?
Here we go.The Acid Rain Problem:Carbon dioxide in the air can dissolve in rain water to form carbonic acid, H2CO3.CO2 + H2O <==> H2CO3Carbonic acid is a weak acid. It partially ionises to form hydrogen ions.H2CO3 <==> H+ + HCO3-The hydrogen ions from carbonic acid give natural rain water a slightly acid pH value of 5.6. Over millions of years this very dilute acidic solution has been responsible for the formation of caves in areas of limestone rocks. Limestone is made of calcium carbonate, which reacts with acids.calcium carbonate + acid = calcium salt + water + carbon dioxideDuring the last century the rain water in some parts of the world has become far more acidic. This acid rain has been caused by the emission of pollutant gases such as sulfur dioxide. When coal is burned in electricity power stations, sulfur impurities form sulfur dioxide.S + O2 = SO2The gas is also produced when fuels obtained from crude oil are burned. When sulfur dioxide is released into the air it reacts with water and oxygen to form sulfuric acid, H2SO4.Sulfuric acid is a strong acid. It ionises completely to hydrogen ions.H2SO4 = 2H+ + SO42-
How is the equation for the formation of acid rain determined?
You know,factory give off billion tons of poisonous gases years which contain sulfur dioxide,nitrogen oxide,carbon dioxide,…When Sulfur Dioxide is blown up:SO2 + H2O >> H2SO3Also:2SO2 + 2H2O + O2 >>2H2SO4When Nitrogen Oxide is blown up:2NO + O2 >> 2NO2Then:3NO2 + H2O >> 2HNO3 + NOAlso:4NO2 + O2 + 3H2O >> 4HNO3When arbon Dioxide is blown up:CO2 + H2O >> H2CO3And the Nitrogen in air will also react with Oxygen when there’re lightning:2N2 + 5O2 >lightning> 2N2O5Then:N2O5 + H2O >> 2HNO3My pleasure to help you :)
What is the equation for formation of nitric acid in acid rain?
Nitric oxide (NO) is formed during lightning storms by the reaction of nitrogen and oxygen, two common atmospheric gases . In air, NO is oxidized to nitrogen dioxide (NO2), which in turn reacts with water to give nitric acid (HNO3) .This acid dissociates in water to yield hydrogen ions and nitrate ions. in a reaction analagous to the lowering the pH of the rain.EQUATIONS ARE -a) N2 (g) + O2 (g) ————-> 2NO (g)b) 2NO (g ) + O2 (g) ————-> NO2 (g)c) 3NO2 (g ) + H2O ——-> 2HNO3 (aq.) + NO (g )
Writing Balanced Equation?
4NO2 + 2H2O + O2 -----> 4HNO3 Nitric acid = formed (thus, it is a product) = HNO3 Nitrogen dioxide = NO2 = reactant ( so it's on the left side) Gaseous Oxygen = O2 = reactant (so it's on the left side of the equation) Water = H2O = reactant (on the left side) To balance, you must be sure that both sides have the same number of elements. Left side: 4-N + 8-O + 4-H + 4-O = 4-N, 4-H, 12-O Right side: 4-H + 4-N + 12-O = 4-N, 4-H, 12-O Thus, the balanced equation is: 4NO2 + 2H2O + O2 -----> 4HNO3 Hope that helps
What is the balanced chemical equation for acid rain?
Acid rain is formed when SO3 dissolves in water, i.e. in droplets that form clouds. As a product H2SO4 is formed. Since SO3 is produced as a common nusproduct in areas with heavy industry, thus these areas are under particular danger of acid rain. So, instead of pure rainwater, diluted H2SO4 falls on the ground. SO3(g) + H2O(l) ---> H2SO4(aq)
Another form of acid rain is one based around a nitrogen-containing acid. What acid might this be?
Nitric acid (HNO3) is one of the acid rains containing nitrogen. N2 + O2 ---lightning---> 2NO NO + 1/2 O2 ------> NO2 NO2 + H2O -----> 2HNO3 + NO The website below provides a fairly good explaination.
Nitric acid is a component of acid rain that forms when gaseous nitrogen dioxide pollutant reacts with gaseous?
...oxygen and liquid water to form aqueous nitric acid. Write a balanced chemical equation for this reaction. So far all I can think of is: NO2+O2+H2O yields HNO3. I try to balance the equation out on both sides but it doesn't look like it's going to happen. I'm pretty sure I'm doing this wrong. Somebody please help me!
Acid rain is formed when sulphur dioxide gas from industry reacts with water to form sulfuric acid. The acid then dissolves marble in statues. Is it correct? And what are the equations?
Usually, sulfur dioxide is released alongside with other pollutants like nitrous oxides, [math]NO_x[/math]. [math]SO_2[/math] doesn't directly turn into sulfuric acid but rather sulfurous acid upon reaction with atmospheric humidity:[math]SO_2 (g) + H_2O (l) \rightleftharpoons H_2SO_3 (aq) [/math]Sulfurous acid by itself is a weak acid. The one that causes acid rain is Sulfuric acid, which is the stronger one. However, in order to form sulfuric acid you need not sulfure dioxide but rather sulfur trioxide, [math]SO_3[/math]. Now comes the role of nitrous oxides.Nitric Oxide (NO), when in contact with oxygen oxidizes into Nitrogen Dioxide: [math]NO (g) + \frac{1}{2}O_2 (g) \rightarrow NO_2 (g) [/math]Nitrogen oxides can interact with UV rays and to produce a phenomenon called 'smog', which is a type of air pollutant. Anyway, when a Sulfur Dioxide molecule comes along, the [math]NO_2[/math] can act as an oxidizing agent to oxidize [math]SO_2[/math] into [math]SO_3[/math]. [math]SO_2[/math] cannot itself be oxidized by atmospheric oxygen gas but [math]NO[/math] can:[math]NO_2(g) + SO_2 (g) \rightarrow SO_3 (g) + NO (g)[/math][math]NO[/math] is regenerated again, so you could say that [math]NO[/math] acts as a catalyst to the reaction. The [math]SO_3[/math] now reacts with the atmospheric humidity to form sulfuric acid:[math]SO_3 (g) + H_2O (l) \rightarrow H_2SO_4 (aq)[/math]This [math]H_2SO_4 (aq)[/math] formed is responsible for acid rain. The process repeats again to form more and more sulfuric acid, so controlling emission nitrogen oxides (which act as catalysts) has a huge impact on reducing severity of acid rain. This is why the recent Volkswagen scandal was so severe.This acid rain can damage marble and limestone (largely calcium carbonate) by reacting with it:[math]H_2SO_4 (aq) + CaCO_3 (s) \rightarrow CaSO_4 (s) + CO_2 (g) + H_2O (l)[/math]
