接触法制硫酸（Contact sulfuric acid） Contact sulfuric acid Discussion on the comprehensive economic benefit of sulphuric acid industry 1. Key difficulties 1. Raw materials for making sulphuric acid in industry. 2. Chemical reaction principle, main production process and typical equipment for producing sulphuric acid from pyrite. 3. Environmental protection and comprehensive utilization of raw materials. Second, the question mark The first order [example 1] you think the measures to reduce acid rain will be taken Use coal as a fuel to build up the factory chimneys and fuel desulphurization to add lime to the acidified soil to develop new sources of energy A. (1) (2) (3) b. (2) (3) (4) (5) c. (1) (3) (5) d. (1) (3) (4) (5) Feel Effective preventive measures can only be taken if the acid rain is known The answer Cause the main cause of acid rain is to discharge a large amount of SO2 in the atmosphere, and therefore using less sulfur coal as fuel, or the fuel desulfurization, and to develop new energy, can reduce SO2 production, thereby reducing the generation of acid rain. So thats choice C. The knowledge of environmental protection is one of the hot topics in the recent college entrance examination. Automobile exhaust (containing hydrocarbons, CO, SO2 and NO, etc.) is the pollutant source of urban air. One way to do this is to install a catalytic converter in the cars exhaust pipe (a catalyst with platinum and palladium alloys). It is characterized by the reaction of CO and NO, the generation of non-toxic gases that can participate in the circulation of atmospheric ecological environment, and promote the full combustion of hydrocarbons and the transformation of SO2. (1) the chemical equation that writes the reaction of carbon monoxide and nitric oxide:. (2) the disadvantage of the catalytic converter is that it increases the acidity of the air to a certain extent. (3) methods to control urban air pollution sources can be found. A. Develop hydrogen energy b. Use electric vehi
