求金考卷答案,,化学,,高一的,,
化学.其实好学.
第一.不要讨厌它.如果做不到喜欢.就做到不讨厌就好了.
第二.看书.习题固然很重要.但课本更重要.每讲一课.你把这一课的课文看3遍以上.
第三.注意一下每一课的方程式.还有各个方程式的反应条件与现象(问问老师每一个方程式的催化剂都是什么.然后记下来.最后一看反应的催化剂和条件就能知道什么方程式了).这个得下点工夫.如果你能背的炉火纯青的话.你不考90也难.
第四.溶解性表.这个是初三必背的.现在也必须背.重中之重!
第五.元素周期表.不用背完.前20必须背.然后学到哪背到哪.
第六.金属的活动性表和非金属的活动性表.背一下.只有好处.没坏处.
第七.找到学化学的感觉和规律.比如:第一章氧化还原反应.除了方程式以外.只用记十个字:失 升 氧 还 氧 ,得 降 还 氧 还
即:失(得)电子.化合价升高(降低).发生氧化(还原)反应.做还原(氧化)剂.得到氧化(还原)产物.
顺便记一个四大反应与氧化还原反应的关系.
第八.找本讲解类的参考书.多看看.
如果你做的到上面的.高三你就可以考化学竞赛了.至少能得个二等奖
补充:
都在这儿了,高中关于碱金属这一章重点就在钠,其他的最多也就十来个,可以通过他们的通性推导,考试一般不作要求。
