Major Pollutant: Ammonia Ammonia is one of the most widely produced chemicals in the United States. In pure form‚ it is known as anhydrous ammonia. Ammonia has the formula NH3 which is a compound of hydrogen and nitrogen. Ammonia is also produced in the human body and is commonly found in nature. It is essential in the body as a building block for making proteins and other complex molecules. In nature‚ ammonia occurs in soil from bacterial processes. It is also produced when plants‚ animals

than van der Waal’s forces. Hydrogen bonding -- When hydrogen is bonded to nitrogen‚ oxygen or fluorine‚ a very strong dipole is formed‚ making the hydrogen very strongly positive. This hydrogen is then attracted to the lone pairs on other similar molecules (nitrogen‚ oxygen and fluorine all have lone pairs) forming a hydrogen bond‚ which is stronger than van der Waal’s or dipole-dipole‚ but weaker than covalent bonding. The effect of hydrogen bonding on intermolecular forces can be demonstrated

Structure and bonding Ionic bonds are chemical bonds formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between an metal and a non-metal. The metal loses an electron or electrons form its highest energy level becoming a positively charged Ion and the non-metal gains an electron or electrons in its highest energy level‚ becoming a negatively charged Ion. Covalent bonds are strong bonds between two non-metal atoms. A covalent bond forms when two

Despite growing interest in examining the role of religion in business ethics‚ there is little consensus concerning the basis or standards of ‘‘good’’ or ethical behavior and the reasons behind them. This limits our ability to enhance ethical behavior in the workplace. We address this

Metallic Bonding Metallic Bonding Why do metals conduct electricity? Metals conduct electricity. The delocalised electrons are free to move throughout the structure in 3-dimensions. They can cross grain boundaries. Even though the pattern may be disrupted at the boundary‚ as long as atoms are touching each other‚ the metallic bond is still present. Liquid metals also conduct electricity‚ showing that although the metal atoms may be free to move‚ the delocalisation remains in force until the
