1 basic chemical concepts and basic theory (10)

1 avogadro constant and gas mole volume

2o2 reaction (electronic transfer direction, number and application)

3 chemical terms: chemical writing, chemical equation writing, ion reaction, ion equation, thermochemical equation。

4 solution, ion co-existence, comparison of the size of non-hydrolysis ion concentrations and their transformation (application of the constant principle), medium and drip。

Five element cyclical “bit-constructive-sex”, i. E. The position, atom structure and nature of the element in the periodic table。

6 chemical keys, reaction heat, gus law。

7 chemical reaction rate, chemical balance, balanced movement (focus on equivalence) - – request for flexibility, which in recent years has been a balanced solution。

8 salt hydrolysis-ion concentration relationships (including size comparisons, solution ph and acid alkalinity)

9 electrochemistry, original batteries and electrolytic tanks (incidents, electrode-reactive forms, total reaction forms, etc.)
