The proportions of nitrogen and hydrogen in a 1/3 ratio is a correct stoichimoetric ratio for the reaction because most reactions use excess reactants to increase the yield‚ according to Le Chatelier ’s principle. The temperature is 400-500 degrees celsius. The reaction is 15% efficient at this temperature‚ but has potential to occur at

A temperature of approximately 37.5 degrees Celsius is known to be the optimal temperature for enzyme conversion. Figure 2 shows that temperatures below this optimal temperature have a lower amount of activity‚ increasing as it becomes closer to the optimal temperature. Temperatures above the optimum

The United Nations panel on climate change projects that the global temperatures will rise 3-10 degrees Celsius by the century’s end – enough to have the polar caps all but melted. If the ice caps melt‚ a vast majority of our states shorelines will be under water. Monuments and great buildings‚ as well as homes and lives will be under water. Essentially my

Microbiology Lab Quiz #2 Study Guide Exercise 9 -- The Gram Stain Compare and contrast simple and differential staining techniques. Simple Staining Simple staining is useful in determining the basic morphology of an organism. Simple staining involves only one reagent i.e. crystal violet‚ basic fuchsin‚ or methylene blue. Simple dyes used to stain bacteria have a positive charge cationic (+)‚ therefore‚ they are attracted to the bacteria that are usually negatively charged anionic (-) Depends

Intro In this essay I will be talking about the History Of Antarctica. First the Human Inhabitants then The Geographic history what lies under the ice and finally the climate history. Body Paragraph #1 Human Inhabitants is there or was there any proof of human life on the ice island‚ Till this day there is no proof of any human life on the ice but scientists may be able to find some in the future. There is a bedrock island under all the ice and there may be some kind of evidence of some type

They say their estimate may be accurate for as long as the next 2‚000 years.’ This is not very encouraging information‚ especially when‚ in the same report‚ according to the World Bank‚ global temperatures may rise as much as 2 degrees Celsius (above the ‘pre-industrial era levels’)‚ over the next 30 years or so‚ due to increasing

Escherichia coli Microbiology Lab NAS 185-14L Introduction In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is

The Effects of pH‚ Temperature‚ Enzyme‚ and Substrate Concentrations on Benzoquinone Production BIOL 2051 June 10th 2013 Introduction Enzymes are the ultimate catalysts of living things. Enzymes are made of proteins which are structured and directed by amino acids chains. Enzymes attract and fit substrate molecules to an active site. The active site binds the substrate molecules covalently to enzyme forming an enzyme-substrate complex‚ which catalyzes

People have been using salt since 6050 bc.We have used it for seasoning‚ preservation‚ and in the last century for lowering the freezing point of water(History of Salt). In pure water 0 degrees celsius is the normal freezing point of water. Ice will melt just as fast the water will freeze. You won’t see the melting and freezing processes as long as they are balanced and equal. Adding salt or any foreign substance to the water upsets the fragile equality between freezing and melting.

Arenes The aromatic hydrocarbons also have the name arenes. They contain in their molecule one or more cycles made up from 6 carbon atoms. When the molecule is formed out of a single cycle‚ the hydrocarbons are mono nucleuses; when the molecule contains more than one cycle‚ the hydrocarbons are poly nucleuses. The simplest aromatic hydrocarbon‚ benzene‚ is compound out of just one such cycle; its formula is C6H6. The representation of benzene through a cycle of 6 carbon atoms with 3 double bounds
