As science and technology are advancing rapidly, the use of chemicals becomes more and more popular. Chemical reactions are taking place in nature and industries anytime. So far, there are more than a hundred elements has been found by people. And every single element has significant impact on the development of the whole world. Sulfur is an important element existing in nature throughout long history. As sulfur is being widely used, human life has changed tremendously. Sulfur plays a necessary role in daily life. It has great effects on industry, agriculture, medical treatment and many other fields. The property and functions of it is still being discovered by people.
The most common allotrope of sulfur is Octasulfur, which widely exists in nature. It is a soft, odourless, bright-yellow solid. Sulfur is insoluble in water and melts at

The contributions of sulfur to the development in science and technology are so great. It has brought people too much convenience in their daily life. Sulfur is always a controversial element. It has both the advantages and disadvantages to people. The advantages of it are the improvement it takes in industry, agriculture and medical treatment or even a small thing that we need to use every day. The disadvantages of it are mainly its polluted gas and some dangerous properties. But comparing the advantages and the disadvantages, the advantages can easily cover its disadvantages. Because if we don’t have the use of sulfur , we won’t develop so fast in science and chemistry. Actually the wasted gas of sulfur is not a very big issue. As the technology of treatment of industrial waste gas become more efficient and people’s environmental awareness is getting stronger. Environmental friendly cannot be ignored in industrial product. Most of the wasted gas is well recycled today. Chemical reactions will never end. The use and the discovery of Sulfur will never
Chemists are the specialists in chemistry, that interact with chemical properties, and reactions. The earth is made up of different gases. Some of this gases are needed for life in the planet but other gases can be harmful to the living. Gas’s use in regular quantities are favorable to the earth. The world started to become more advance and had to use more of this gases to produce everyday objects and inventions by men. Little did we knew this chemicals we going to affect us in our life. Chemist Jose Mario Molina actually discovered that chlorofluorocarbons were affecting the ozone layer.
Sulfur is also in some proteins and vitamins. Some people have even sprinkled sulfur in their yards to get rid of snakes, but it should not be used if you have pets or children. There are some organic compounds of sulfur which include, calcium sulfur, carbon disulfide, sulfur dioxide, and hydrogen sulfide. Sulfur dioxide is a dangerous component of sulfur and is an important component of sulfur. Certain medications that contain sulfur help treat depression, fibromyalgia, arthritis, interstitial cystitis, athletic injuries, congestive heart failure, diabetes, cancer, and AIDS.
Note to environmentalists: The sulfuric acid was completely neutralized and properly discarded. Credits I would like to thank all the people who helped me with this project. I would especially like to thank my mother, for letting my go through an abundance of Baking Soda, Vinegar, and many of our other household items. I would like to thank my Father for helping me understand the science of this project, and my whole family for helping me do well. I'd also like to give credit to the following Brands of substances I used: Arm & Hammer Drano Revco Aspirin Mylanta Seaway And any other products I may have used along the way.
One of the biggest environmental problems that needs dealing with in society today is acid deposition. It is largely caused by humans, and causes much pollution to the environment and harms people and buildings as well. Although there are minimal positive sides to this issue, the negatives far outweigh it and call people around the world to take action to reduce and even solve this problem. Coming in both wet and dry forms, acid deposition consists of acidic pollutants including nitrogen oxides and sulfur oxides that have been deposited from the atmosphere to the surface of the earth. There are both wet and dry forms of acid deposition, wet forms being referred to as acid precipitation. Acid precipitation is the result of sulfur and nitrogen oxides reacting in the atmosphere with water vapor. This returns to the earth as acid rain or snow. Dry deposition occurs when these oxides react without water and they settle out of the atmosphere onto the earth. Acid deposition can come from a number of different sources such as smokestacks, trucks and cars. More than 90% of the sulfur in the atmosphere comes from humans. Coal burning, the smelting of metal sulfide ores, and automobile exhaust are major human contributions to sulfur dioxide in the atmosphere. Similarly, 95% of the increased nitrogen oxide levels in the atmosphere are a result of the activities of humans. The activity that contributes the most to these elevated levels is the combustion of oil, coal, and gas. Attention was first drawn to acid deposition in the 17th century when the bad effects of industry and acidic pollution on both vegetation and people were noticed. In the 1960s, it became an international problem when fishermen noticed declines in fish numbers and diversity in lakes across North America and Europe. Acid deposition causes many problems such as these worldwide, and is clearly a problem that needs to be properly dealt with.
We had begun to experiment with the elements, trying to accomplish transmutation and creating the “elixir of life”. In china, their alchemists were trying to create the “elixir of life” for their emperors. The elixir was said to cure any disease and/or give one eternal life. However, the ingredients they were using were questionable. They had used substances like arsenic, mercury, and sulfur. Alchemists had transformed the chemical elements into the first rudimentary periodic tables and introduced the process of distillation to Western Europe. Also, they were among the first to extract metals from ores and compose various inorganic acids and bases. Alchemist were the ones to lay down the stepping stones to the creation of
Hydrogen sulphide has a boiling point of -82 degrees Celsius and a melting point of -60 degrees Celsius. There are 2 hydrogen and 1 sulphide molecule. Simple molecule’s which are covalent have lower melting and boiling points as they do not need too much energy to separate the bonds because they are as polarised as water. In hydrogen sulphide the intermolecular forces are known as Dipole-Dipole forces which are less powerful than hydrogen bonding which is in water therefore water has the strongest bond compared to hydrogen chloride and hydrogen sulphide. Water is more electronegative than hydrogen chloride and hydrogen sulphide because there are more molecules in water which are drawn together however in hydrogen sulphide there are less molecules
Do people know what happens to things that they throw away? They think it gone for good, but scientists worry that if methane increases in the atmosphere, it could cause more warming than carbon dioxide when they burn the fossil fuels. It is important to know because of the methane from landfills because it is estimated that it causes between thirty and seventy million tons of emissions every year (Reay, n.d.). It is necessary to understand the sources and advantages, and disadvantages, of methane because it is dangerous because it can affect the environment.

The concept of Green Chemistry helps scientists utilize materials found here on Earth to better improve our environment from an internal decadence. With the exponentially increasing number of the human population there creates an enormous strain of the use of our natural resources, which thereby requires a need to produce an alternate source, either through chemical, or machinery means, which then leaks problems, such as pollution, into our environment. However, using the concepts of Green Chemistry, which includes, enhanced atom productivity, and the usage of non-renewable resources along with many others, scientists can better neutralize the damaging effects of pollution in our environment. Professor Barry M. Trost received an academic award for his work in developing the concept of atom economy, in which he discovered a way to reduce the amount of chemical waste, while also improving the efficiency of chemical reactions.
Sulfur is the third most abundant mineral in the human body after calcium and phosphorus and is vital for the proper functioning of the body. Sulfur plays a big role in the oxygenation and detoxification of all cells. Without it, your body simply cannot mobilize and release toxins; toxins will remain embedded in the body’s cells, which will then eventually make us sick.
Sulfur is the 16th chemical element present on the periodic table of elements. Although the element is colorless, it appears as a yellow colored crystal shaped solid at room temperature. Sulfur is widely used around the world from medicine all the way to fertilizers. It serves a huge purpose in the world today as it is beneficial to many things such as crops in agriculture, fertilizers, medicine, cosmetics, rubber products, skin products, natural resources and most importantly in the oil and gas industry. It assists with many health benefits such as decreasing acne, in combination with alcohol it can be used to treat skin disorder. The human body itself is comprised of 0.25% sulfur. Figure 1 shows a visual representation of sulfur in its solid state at room temperature. [10]
The advancement of humanity requires constant effort to know the unknown. Chemists do the interesting job of studying the composition of matter and its properties. Investigating what constitutes the things around us and extracting the useful knowledge from it has always proved beneficial to mankind. I became fascinated by studying chemistry during my last two years of high school. Pursuing my interest, in 2006, I started my bachelors program at Taibah University. Madinah, Saudi Arabia, then in 2012, I started my masters program at Sacred Heart University with expected graduation in Dec 2014. In fact, the education at Taibah University and Sacred Heart University deepened my understanding of chemistry.
Do humans realize how chemical engineering has changed their life? Nowadays, chemical engineers work very hard to develop the quality of people life through different technologies and methods. The design and the production of everything people have, it comes from the talents in the chemical engineering field. In fact, the development in chemical engineering helps to produce effective materials, explore and use more efficient and long-lasting resources and save the environment by developing alternative technologies and processes to reduce pollutants. Advances in chemical engineering have brought many benefits which contributed in changing the world to be a better place. The three most important benefits of advances in chemical engineering could
Pollution is one of the most ignored concepts in the modern world. It is a topic that often gets forgotten by talk of conservation, sustainability, climate change and energy issue, perhaps, because it is a complex subject with lots of sources and lots of effects. In spite of the fact, that pollution is one of the biggest global killers. At the same time, it can be solved in our life time, and the solutions are relatively low-cost. There are some major substances that may cause pollution, such as: Nutrients, Pesticides, Heavy metals, and suspended solids.
The world we live in is full of chemicals and elements, we just do not simply notice them. In Everyday life there are acids, bases, and salts. Some may not know how to see them or even what they are. You might put baking soda into vinegar to see what happens afterward. We put salts on our food to make it taste better. There is salt in every ocean on earth. There are so many acids, bases, and salts around us and we just do not see them. We eat a neutralizer when we get heartburn from the acid in our stomachs. Science is all around us.
