vehicles‚ we suggest installing a 3-way catalytic converter‚ which can oxidize carbon monoxide to carbon dioxide 2CO + O2 ---> 2CO2‚ unburnt hydrocarbons to carbon dioxide and water CxH2x+2 + (3x+1)/2 O2 ---> xCO2 + (x+1) H2O and reduce nitrogen oxides to nitrogen and oxygen 2NOx ---﹥N2 ＋ xO2. Nevertheless‚ the catalytic converter cannot be used on leaded petrol vehicles because Lead will poison the catalyst such as Platinum inside the converter. Indeed‚ there are more possible solutions to solve

Based on the conditions of early Earth‚ what conclusion can you draw about the amount of anaerobic respiration that was occurring at Earth’s beginning? Explain your answer. A: The atmosphere of early Earth was made up with almost of different nitrogen gases‚ water vapor and carbon dioxide. There wasn’t any pure oxygen or I should say there wasn’t any breathable oxygen in the air in those days. The first form on earth had to develop in the absence of oxygen using the anaerobic respiration. All

Kristina Matthews Environmental Science – EVS 1001 2 4/23/13 Week 2 Individual Work There are human impacts that deal with four chemical cycles. The first cycle is to do with carbon. The second is to do with phosphorus. The third cycle is nitrogen. And the fourth cycle is sulfur. We will look at each one and how they impact humans and examples. Carbon effects human impact. “Human intrusion into the carbon cycle is significant. As we will see shortly‚ we are diverting (or removing) 40 % of

will work including the mass and energy balance across the plant. What is Ammonia Ammonia (NH3) is a stable compound and is used as a starting material for the manufacture of many important nitrogen compounds and can also be directly used as fertilisers. It is produced by reacting hydrogen and nitrogen. It is a colourless gas with a sharp odour. The boiling point is -33.35oC and its freezing point is -77.7oC.1 Care must be taken when handling ammonia as can cause deep burns in the skin; irritation

February‚ 2011 Title: Analysis of the Elements present in Organic Compounds Aims: To test the presence of Carbon‚ Hydrogen‚ Oxygen‚ Nitrogen and Sulfur in Organic Compounds Introduction: Organic Compounds can be considered as any compound containing carbon atoms covalently bonded with other atoms‚ usually hydrogen. Other atoms may include oxygen‚ nitrogen‚ sulfur…etc. They can be found in nature‚ since “organic” means present in‚ or derived from‚ plants and animals. Materials/ Apparatus:

It is made up of seven carbon atoms‚ eight hydrogen atoms‚ four nitrogen atoms‚ and two oxygen atoms. Theobromine is very similar to caffeine but is ten times weaker. Caffeine has two more hydrogen atoms than theobromine. The structure of theobromine also contains two amide groups and three amine groups. Theobromine
