Discuss different strategies for producing wine with low or no SO2. Is there global demand from consumers for such wines? SO2‚ sulfur dioxide has been considered as one of the essential additives for making sound wine‚ which acts as antioxidant and antiseptic. History of sulfur in wine dates back to Roman times when they discovered that wine was kept fresh by burning sulfur candles inside empty wine vessels. However‚ the number of wines produced with low or no SO2 is increasing in these 10 years‚ and

Nitric acid is a highly reactive oxidizing agent used in making fertilizers‚ explosives‚ and rocket fuels‚ and in a wide variety of industrial metallurgical processes. It is also a component of acid rain. Its chemical formula is HNO3 and it has been known as “aqua fortis”‚ which means strong water‚ to alchemists. It is a transparent‚ colorless to yellowish‚ fuming corrosive liquid. Nitric acid is a strong acid and therefore it completely dissociates in water. It has a gravity of 1.41 and the concentration

Biller Essay November 2‚ 2009 Argument Essay Almost everyone enjoys taking a bicycle ride on a beautiful summer day. Many towns have wisely spent their money on building a bike trail. Mt. Pleasant‚ the town I live in‚ has never had a bike trail that I can remember of until recently. The town constructed a historical trail approximately fourteen miles long called the Coke and Coal Trail. Although it is a very grand trail already‚ it is still only new. The serious issue at hand is the many problems

Assessment 1) Describe the difference between ionic and covalent bond. Ionic bonds have electrostatic forces that hold cations and anions together‚ and are electronic neutral. Covalent bonds are bonds that don’t give or take any electrons. In stead they share the elctrons 50) Which of these compounds contain elements that do not follow the octet rule? Explain. a) NF3: 5 + (7*3) = 26 b) PCl2F3: 5 + (7*2) + (7*3) = 40 c) SF4: 6 + (7 *4) = 24 d) SCl2: 6 + (7*2) = 20 The answer is “d”

It is a mixture of sulfur‚ charcoal‚ and potassium nitrate (saltpetre)—with the sulfur and charcoal acting as fuels‚ while the saltpeter works as an oxidizer.

An example of the attempted preservation of the environment may be‚ that an industry may only emit a tone of sulfur dioxide over a year but‚ next year the permit will lower the amount of sulfur that is allowed to be produced. Thus‚ firms most invest more money into machinery that is more environmentally friendly. Since tradable permits can be traded‚ the permit will move
