One of the most significant current discussions in sustainable aviation is alternative fuel for airplane‚ which is a serious argument; however‚ big question is that efforts to produce a more sustainable fuel to power aircraft are technically and ethically feasible. This paper going to investigate and show there is no alternative fuel to power aircraft in this time. The fuel using by airplane is fossil fuel‚ which is Jet A1 by burning this fuel there are impact on the global warming the researcher

CHAPTER I AIR POLLUTANTS: SOURCES AND CONTROL OF GASES Introduction: 1. According to the World Bank‚ in 2007 air pollution cost about 3.8% of China’s 2. gross domestic product‚ mainly from diseases and loss of lives. 3. World Health Organization estimates that in India alone about 500‚000 premature deaths are caused each year by indoor air pollution. 4. Serious respiratory disease-related problems have been identified for both indoor and outdoor pollution in major cities of several countries. 5.

Structural Effects on Stability and Reactivity. Organic Chemstry Laboratory Structural Effects on Stability and Reactivity Introduction The concepts of stability and reactivity are fundamental to understanding chemistry. In this chapter we consider first the thermodynamic definition of chemical stability. We then consider chemical kinetics (Section 3.2) and how it can provide information about reactivity. We also explore how structure influences stability and reactivity. We want to learn how

C H A P T E R 5 Basic Concepts from Organic Chemistry 5.1 | INTRODUCTION The fundamental information that environmental engineers and scientists need concerning organic chemistry differs considerably from that which the organic chemist requires. This difference is due to the fact that chemists are concerned principally with the synthesis of compounds‚ whereas environmental engineers and scientists are concerned‚ in the main‚ with how the organic compounds in liquid‚ solid‚ and gaseous wastes

CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value
