化学方程式与溶液结合的计算是初中化学中的重点内容,也是中考化学必考内容之一,虽然不是压轴题,但也有一定的难度和技巧。综观近几年此类中考化学试题,不少试卷都有这样一个特点,就是将其与图像函数结合进行命题,通过文字及图像来共同提供信息。它们涉及的化学方程式及图像虽有所不同,但解题路径却是异曲同工。下面选取2008年典型的中考试题进行例析,供大家借鉴。 Calculation of chemical equation and solution is the key content of junior high school chemistry, which is one of the necessary examinations in the senior high school entrance examination. Although it is not a finale issue, it also has some difficulties and skills. In recent years such a comprehensive examination of chemical exam questions, many papers have such a characteristic, that is, combining it with the image function proposition, through text and images to jointly provide information. Although they involve different chemical equations and images, the problem-solving path is similarities and differences. The following selected 2008 typical senior high school entrance examination questions for analysis, for your reference.
