1 in vapour state sulphur partly exists as S2 molecule which has 2 unpaired electrons in the antibondind pi orbitals jus lyk oxygen and thus exhibits paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative

Sulfur and ammonia‚ the stench of the chemicals clung to the air coupled with the macabre scent of burnt flesh‚ a smell that simultaneously reminded one of a hospital and a barbecue. Three bodies lay torn asunder and charred on the streets of Tiber city‚ jagged black lines burnt into the surrounding brick walled alleyway. Sebastian Thorn was familiar with such scenes of flagrant violence‚ the handy work of an unlicensed mage‚ lightning was what had turned these people into charred corpses and burned

Travelling along a conveyor belt‚ workers place the apricots onto hygienically pre- prepared red wood trays‚ facing them upright and removing unwanted products. 8. The apricots are then treated by sulphur dioxide‚ in the sulphur room where they are cured. 9. They are then left in a cool room at 50C overnight. 10. Not until the next day‚ apricots are placed into the dry yards for sun- drying. They are left there for two days

does it affect human when we swim in a really high acidic ocean. Acid rain is a mixture of water and gases that have a pH of 5 or lower and it is found in our atmosphere. Acid rain is made out of two main gases nitrogen dioxide which is formed from cars‚ and sulfur dioxide which is made from factories which burn coal. Acid rain or acid deposition has two main forms that are wet deposition or dry deposition: wet deposition is a form of precipitation and dry deposition is in a form of gases or microscopic
Premium Acid rain Oxygen Sulfur dioxide
The causes of acid rain are because of the emissions of sulphur dioxide and nitrogen oxides in the atmosphere. This is a result of pollution; sulphur dioxide primarily the result of industrialisation and coal fired power stations‚ and nitrogen oxides produced mainly due to car exhaust fumes. These either form wet or dry deposition‚ and the effects we can see today. It could be argued that once that the human race has used up all of the planets coal reserves‚ the problem of acid rain would disappear

How carbon dioxide may affect organisms directly and indirectly Carbon dioxide is a molecule that is essential to the survival of nearly all organisms on our planet‚ as in some way or another they rely on carbon dioxide or its products to provide them with respiratory substrates. However‚ as I will elaborate later‚ carbon dioxide also has adverse effects on organisms. Carbon dioxide primarily affects all organisms as it is essential for the process of photosynthesis‚ in which organic compounds

I will use cress seedlings‚ which germinate quickly and can grow a few centimetres in a matter of days and sodium metabisulphite‚ which reacts slowly with water to produce sulphur dioxide gas. The seedlings will have to be in an enclosed system so the sulphur dioxide does not escape. The experiment is a simulation trying to model a powerstation producing sulphuric acid‚ falling on the seedlings as acid. Research QuestionHow do different concentrations of acid rain affect

Does Human-Produced Carbon Dioxide Contribute to Global Warming? There are always two sides to an issue. This is especially true in Science. Each side will gather facts and statistics to help their argument. They will also fuel the argument with their opinions. Some articles are more persuasive in their reasoning then others. This persuasion can ultimately change a person’s opinion of the issue. The question to be answered is does human-produced carbon dioxide contribute significantly to

Chapter 2 22. A student heats 0.5585 g of iron with 0.3550 g of sulfur. She reports that she obtains 0.8792 g of iron sulfide and recovers 0.0433 g of unreacted sulfur. Show by calculation whether or not her results obey the law of conservation of mass. Total mass initial = 0.5585 g + 0.3550 g = 0.9135 g Total mass final = 0.8792 g + 0.0433 g = 0.9225 g These two values should be equal by the law of conservation of mass. These results do not obey the law of conservation of mass. Possibly she

INTRODUCTION From natural gas‚ crude oils‚ and other fossil materials such as coal‚ few intermediates are produced that are not hydrocarbon compounds. The important intermediates discussed here are hydrogen‚ sulfur‚ carbon black‚ and synthesis gas. Synthesis gas consists of a nonhydrocarbon mixture (H2‚CO) obtain- able from more than one source. It is included in this chapter and is fur- ther noted in Chapter 5 in relation to methane as a major feedstock for this mixture. This chapter discusses
