该考点的命题方向主要是通过设置实验、问题情景,让学生阅读、思考后,根据所学的一氧化碳的化学性质,以及反应现象、化学方程式等来分析、解答相关的实际问题。并且,经常将其与“碳及含碳物质的不完全燃烧”“氧气的化学性质”“炼铁的原理及金属的冶炼”“一氧化碳的毒性及煤气中毒”“一氧化碳的用途”等联系起来考查。题型有选择题、填空题、实验探究题。中考重点是考查学生对一氧化碳的化学性质的掌握情况,以及运用它来分析、解答相关的实际问题的能力等。
The proposition of the test center is mainly through the setting of experiments, problem scenarios for students to read, think about, according to the chemical properties of carbon monoxide learned, and reaction phenomena, chemical equations to analyze and answer relevant practical problems. And often with the “incomplete combustion of carbon and carbonaceous substances,” “chemical properties of oxygen,” “the principle of ironmaking and metal smelting ” “carbon monoxide toxicity and gas poisoning ” “Use of carbon monoxide” and other linked to examine. Questions are multiple-choice questions, fill in the blank questions, experimental questions. The focus of the exam is to examine students’ mastery of the chemical properties of carbon monoxide and the ability to use it to analyze and answer relevant practical problems.
