The United States chemical industry makes more sulfuric acid than any other chemical. One process uses hydrogen sulfide from “sour” natural gas wells or petroleum refineries as a raw material. Write a balanced equation, without including states, for each of the steps leading from hydrogen sulfide to sulfuric acid: a) Hydrogen sulfide (which could be called dihydrogen monosulfide) combines with oxygen to form sulfur dioxide and water. b) The sulfur dioxide reacts with more hydrogen sulfide to form sulfur and water. (Sulfur is described as both S and S8 in chemical equations. Use S in this equation). c) After imp
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

b) The sulfur dioxide reacts with more hydrogen sulfide to form sulfur and water. (Sulfur is described as both S and S8 in chemical equations. Use S in this equation).
c) After impurities are removed, the sulfur is reacted with oxygen to form sulfur dioxide.
d) Sulfur dioxide reacts with oxygen to yield sulfur trioxide.
e) Sulfur trioxide and water combine to make sulfuric acid, H2SO4.
