热化学方程式是高考的重点和热点,纵观全国和各省市历年高考中的试题出现情况可以看出,重现率最高的是热化学方程式的正误判断和根据给定条件书写热化学方程式.事实上,热化学方程式的正误判断,实际上就是热化学方程式的正确书写的变形考查.若要准确、快速地判断出热化学方程式是否正确,则要能够正确、熟练地掌握热化学方程式的书写,并明确书写热化学方程式的有关规定和注意事项.为了提高广大考生判断热化学方程式正误的准确度和速度,特对设计热化学方程式错误的常见方式进行总结,并对其解答技巧进行点拨,以便促
The thermochemical equation is the focus and hot spot of the college entrance examination. Looking at the examination questions in the entrance exams of the whole country and provinces in the past years, we can see that the highest recurrence rate is the right and wrong judgment of the thermochemical equation and the thermochemical equation according to the given conditions. On the thermochemical equations of the positive and false judgments, in fact, is the thermochemical equation of the correct writing distortion test to accurately and quickly determine the thermochemical equation is correct, we must be able to correctly and skillfully grasp the thermochemical equation writing, And clearly written thermochemical equations of the relevant provisions and precautions.In order to enhance the majority of candidates to determine the accuracy and speed of thermochemical equation is wrong, especially on the design thermochemical equation common mistakes summarized, and tips to answer their skills in order to promote
