Answer: Acid rain.
Explanation:
According to some experts, acid precipitation can lead to acid rain. Acid rain is a product of chemical reactions caused by the release of compounds such as sulfur dioxide and nitrogen oxides into the air. These substances can form in the atmosphere itself and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
There are specific theories that nitrogen oxides cause acid rain, in other sulfur oxides, which are produced by the combustion of coal or petroleum products, for example, in thermal power plants, automobile engines, and plants for the production and purification of metals. With water vapor, they produce nitric or sulfuric acid, respectively. This natural disaster is very bad for flora and fauna, it has a particular negative reflection on forests and the aquatic world, especially fish.
Iron(III) oxide is insoluble in water but dissolves readily in strong acid, e.g. hydrochloric and sulfuric acids. It also dissolves well in solutions of chelating agents such as EDTA and oxalic acid.
Two factors that determine whether a molecule is polar are the types of atoms in the molecule and the SHAPE of the molecule.
A polar molecule is a molecule with two opposing charges, one end of the molecule has a partial negative charge while the other end has a partial positive charge. This occurs because the molecule is not totally symmetric. The polarity of a substance is typically determined by the characteristics of its constituent atoms and the shape of the molecule. Polar molecules are usually bent or trigonal in shape.
