学习化学旨在使当今高中生增强对环境污染的认识。当前,主要有三大环境问题:大气污染、水污染、土壤污染。针对目前日益恶化的环境问题,高中化学理论在环境污染方面的解释如下:CO2与温室效应:矿物燃料燃烧后,产生CO2、CH4、N2O…,更多阳光进入地面,对红外线有强烈吸收作用,使大气温度上升。SO2与硫酸酸雾:(高一化学氧族元素)SO2来自含S的煤、石油的燃烧,H2SO4厂,矿物煅烧:2SO2+O2=2SO3、SO3+H2O=H2SO4。在SO2、NO2和水作用下形成酸雨,它将使土壤、江河、湖泊酸化。
Learning chemistry aims to increase awareness of environmental pollution in high school students today. At present, there are three major environmental issues: air pollution, water pollution, and soil pollution. In response to the current deteriorating environmental issues, the high school chemical theory explains the following aspects of environmental pollution: CO2 and greenhouse effect: after burning fossil fuels, produce CO2, CH4, N2O..., more sunlight enters the ground, has a strong absorption of infrared light, Increase the atmospheric temperature. SO2 and sulfuric acid mist: (higher chemical oxygen element) SO2 from the combustion of coal and petroleum containing S, H2SO4 plant, mineral calcination: 2SO2 + O2 = 2SO3, SO3 + H2O = H2SO4. Acid rain is formed under the action of SO2, NO2 and water, which will acidify soil, rivers and lakes.
