Ammonia

    Ciao and good evening,today I would like to talk about Ammonia. okay,ammonia was a very useful compound in the industry. most of ammonia are used for nitrogen fertilisers. Besides that, Ammonia also used for manufacturing of nitric acid through ostwald process, also used in manufacturing cleaning agents such as detergent and for manufacture some explosive materials.

      Okay, lets talk about Ammonia characteristics. Ammonia was a colorless gas and smelly. Ammonia density also less than air.hmm..i think its enough for you guys to know.

     Okay, let's move on.Ammonia was produced by the reaction between nitrogen gas and hydrogen gas in haber process. Nitrogen gas that in haber process was obtained from the reaction between steam and coal(carbon) or natural gas. In haber process, one volume of nitrogen and 3 volume of hydrogen get mixed up and  react at optimum condition as follows:- under 200 to 500 atmosphere
   pressure      
                   - 450 to 550 temperature heat
                   - ferum powder as catalyst

After that,the ammonia that we got is cooled as liquid.

     Having said that, the process of making Ammonia would cause an impact to environment,which is global warming due to the released carbon dioxide from haber process. What's more,the widespread use of fertilisers cause a pollution.For instance, eutrophication. Moreover, when the fertilisers are washed off fields and into rivers or in water,it'll cause algae to grow. The algae die off when they have exhausted the nutrients. The algae are then decomposed by aerobic bacteria,which used up all the oxygen and cause the aquatic ecosystem to collapse.

    That's all from me..Ciao
