chemical-rich and contain high amounts of nitrogen‚ phosphorus and potassium. On the other hand‚ the main difference between a chemical fertilizer and an organic fertilizer is that the chemical fertilizer comes out of a lab and the organic fertilizer comes from living beings. A chemical fertilizer is synthetically prepared to include the vital nutrients that are necessary for the plant growth process. All chemical fertilizers contain the normal NPK (nitrogen‚ phosphorus‚ and potassium) requirement

Method and the Problem-Solving Approach My hypothesis for the small amount of information would be the reason for the fewer fish and higher amount of algae may be due to algae blooms. Algae blooms are due to a rapid increase of algae and too much nitrogen in the water. From this information‚ I can deduce that there is a runoff problem from one or more of the farms where fertilizer is being spread and is entering into the lake. This in turn creates massive algae growth which not only blocks out sunlight

pounds of air for each pound of gas‚ the mixture is rich. The exhaust from the combustion in a cars engine is comprised of six main ingredients. Nitrogen gas‚ carbon dioxide‚ and water vapor are three of the main emissions. These gases do not cause damage to the atmosphere like the other gases do. Carbon Monoxide‚ other hydrocarbons‚ and Nitrogen Oxides result in a majority of the pollution caused by cars. Carbon Monoxide is a colorless and odorless gas that can kill you if too much is inhaled

What are the consequences of cutting down trees? There are many consequences for the environment of cutting down trees. Known as deforestation it has huge effects on the environment. It one very big effect is the loss of biodiversity which is a direct effect of cutting down trees. There are many reasons of which humans act out deforestation. For example is so that we can set up cattle farms. Also grow crops of which can then be sold to people. Another reason is for urbanisation and for the building

germination rates. 2. Introduction Fertilisers are widely used in agricultural production because they contain essential compounds such as phosphorus‚ nitrogen and potassium that have been depleted from most Australian soil. The phosphorus is responsible for the development of the plants‚ providing healthy growth and strong roots. Nitrogen furnishes a major component of chlorophyll where it’s known for its ability to grow green leaves. Potassium provides a measure of disease resistance to plants

CALCULATIONS INTRODUCTION The first part of this ‘Chemical Calculations’ topic will help us to work out QUANTITIES involved in a reaction; For example‚ a manufacturer might want to know‚ How much ammonia will I produce from 20 tonnes of nitrogen in the Haber Process? To do these calculations you will need to be familiar with the term Ar (relative atomic mass)‚ Mr‚ Molar mass and Mole. Relative Atomic Mass – Ar • The Ar tells us the average mass of an individual atom (average because

much needed by vegetation‚ namely Nitrogen and phosphorous. The Nitrogen in the fertiliser is in the form of ammonia or ammonium‚ these are converted by nitrifying bacteria into nitrites‚ and then a different kind of nitrifying bacteria converts the nitrites into nitrates. The nitrates are taken up into the plant through the roots where they are assimilated into amino acids which are used for protein and DNA synthesis. Naturally the plants die returning the Nitrogen to the soil as nitrates‚ proteins

and hence‚ the quicker the oxide film grown. The oxide film quality is better than that grown when the temperature is low. 2. Steps of wet oxidation 1. There are two nitrogen sources in an oxidation system‚ one for process application‚ with higher purity‚ and another with lower purity for the chamber purge. 2. Nitrogen is used because it is a stable gas and will not react with silicon even at 900oc. 3. For wet oxidation‚ high purity oxygen gas is used to oxidize silicon. 4. Since the

Process combines nitrogen from the air with hydrogen from natural gasses like methane into ammonia. This process is a reaction that ’s reversible and the production of ammonia is exothermic.
