pollutants such as carbon monoxide‚ nitrogen oxides‚ sulfur oxides and hydrocarbons are produced as fossil fuels are used (Union of Concerned Scientist‚ n. d.). Carbon monoxide causes headaches and aggravates people with heart disease. Nitrogen dioxide and nitric oxides create smog‚ a yellowish-brown “cloud” layer that settles on the ground. And these substances irritate lungs causing issues like bronchitis and pneumonia. Sulfur oxides and nitrogen oxides are the primary components of acid rain and

solution of nitric acid (HNO3) through a pipe. The ammonia combines with the nitric acid to form ammonium nitrate. The formula for this reaction can be written as NH3 + HNO3 → NH4NO3. Large amounts of heat are released during the reaction‚ so the pipe and supporting equipment must be very strong. The solution of ammonium nitrate in water is allowed to evaporate‚ leaving behind pure white crystals of the compound.

Harmful metabolites like nitric oxides can also be dispersed and limited in hope to rescue the dying cells (T Nakase‚ Sohl‚ Theis‚ Willecke‚ & Naus‚ 2004).

But there are different kinds of pollution—some visible‚ some invisible—that contribute to global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered as air pollution. Air pollutant Carbon dioxide dioxide

Afterwards‚ I added sodium hydroxide‚ and my solution colored to a dark blue solution called copper hydroxide. I heated the solution to evaporate the water and I got a brownish-blackish solid called copper oxide. Once the solid appeared‚ I poured in sulfuric acid to it and I got copper sulfate‚ a bluish solution

Acid Rain Sulfur and nitrogen oxides are released from industrial factories‚ electrical power plants‚ smelting plants and motor vehicles. When these gases combine with the moisture in the atmosphere‚ they return to the ground as sulfuric acids and nitric acids. These are popularly known as Acid Rain‚ and it bring damages to lakes‚ the soil‚ forest
