Economic Growth and environmental problems The industrial revolution‚ which began around 1750‚ ushered human beings into a new era of modern civilization. While the remarkable progress in science and technology has improved people’s lives greatly‚ our earth is changing and the environment around us is becoming worse and worse. According to Booth (1991‚ p.552)‚ the" long-run economic growth relies on the creation of new industries and new forms of economic activity‚ these new forms of economic activity

Acidification When ammonia reaches the soil surface‚ it usually reacts with water in the soil and is converted into its ionic form‚ ammonium (NH4+) and absorbes to the soil. The ammonium in the soil eventually disassociates or is nitrified into nitrite (NO2-) or nitrate (NO3-) by nitrifying bacteria‚ releasing H+ ions into the soil (3‚ 4). If not taken up by biomass and converted to methane‚ the surplus H+ ions eventually lead to the formation of an acidic soil environment. The nitrogen left over in the

Unit 8 Textbook Notes 12.1 The N2O4-NO2 Equilibrium System When you put a sample of N2O4‚ a colorless gas‚ in a closed container at 100C a reddish-brown color starts to show. This is due to NO2 formed by the decomp. of part of the original substance. The forward and reverse reactions are taking place at the same rate. The concentrations of species present remain constant with time. These concentrations are independent of the direction from which equilibrium is approached. The equilibrium constant

The Rate of a Reaction The area of chemistry that deals with the rate or speed of chemical reactions is known a chemical kinetics. The word “kinetic” is derived from the Greek name kinitikos that means movement or motion. In the present context‚ the kinetic means the reaction rate or rate of a reaction that is defined as the change in concentration of a reactant or a product with time (M/s). Chemical reaction can be represented by the following general equation. Reactants Products It is very important
