Answer. It is a combustion reaction in which ethane is oxidised by oxygen, burns and produces carbon dioxide and water vapour as by products. It’s also a redox reaction.

A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products. Usually, a double displacement reaction results in precipitate formation. The chemical bonds between the reactants may be either covalent or ionic.

Combustion reaction

This is a gas evolution reaction, O 2 is the formed gas.

The Lewis acid-base reaction between SO3 and H2O to form H2SO4 is the reaction that is the primary cause of acid rain. The oxygen atom of the water molecule contains two lone pairs, so water is a Lewis base, while the sulfur atom in SO3 has only three electron regions, which makes SO3 Lewis acidic.

SO3 (Sulfur trioxide) is a Lewis acid mainly because the sulfur atom in SO3 has only three electron regions. The sulfur atom tends to accept an electron pair. Besides, SO3 is also a non-metal oxide which is acidic in nature.

Emissions of sulfur trioxide (SO3) are a key component of plume opacity and acid deposition. The emissions Of SO3 from such a boiler depend on coal sulfur content, combustion conditions, flue gas characteristics, and air pollution devices being used.

Touching sulfuric acid will burn your skin, and breathing sulfuric acid can result in tooth erosion and respiratory tract irritation. Drinking sulfuric acid can burn your mouth, throat, and stomach; it can result in death. If you get sulfuric acid in your eyes, it will cause your eyes to water and will burn.

Health and Environmental Effects Sulfur trioxide is an air pollutant that affects the lungs and makes it hard to breath. Sulfur oxides, both SO2 and SO3, are constituents of acid rain.

It is corrosive to metals and tissue. It causes eye and skin burns. Ingestion causes severe burns of mouth esophagus and stomach. The vapor is very toxic by inhalation.

In SO3 there are three double bonds, and no lone pairs at sulfur. Adding two extra electrons changes that by giving two more electrons to sulfur. SO3 is sulfate trioxide, while SO3 -2 is called the sulfite ion.

When sulphur trioxide is passed through water. It produces sulphuric acid.

Given that simple fact here is a quantum mechanical rationalization: Sulfur can expand its octet, which means in SO2 it has 12 electrons ‘around’ it. Hence SO2 should be a better structure than SO overall.

Sulfur monoxide is an inorganic compound with formula SO. It is only found as a dilute gas phase. When concentrated or condensed, it converts to S2O2 (disulfur dioxide). It has been detected in space but is rarely encountered intact otherwise.

In Lewis Structure of SO3, there are 12 electron in valance cell of sulphur atom and therefore SO3 is a Hypervalent specie and exception to octet rule.

Statement 1: The structure of SO3​ shown by using more than one structural formula. Statement 2: SO3​ is very unstable and resonates between these possible structures.
