我成日睇電影見到d人用chem方法令到explose(爆炸), 到底點整ga?

Mg + 2HCl ---> MgCl2 + H2 + energy

I think its better to use Na or K. Cs is the best.

2Cs + F2 -> 2 CsF

Any reaction which is extremely fast, and also highly exothermic or release a large amount of gas, causes explosion.

Cs is too dangerous to handle under normal condition

Concentrated HCl (e.g. 12M HCl) would do the job very good and stable without any protection.  Do do it at home though.

H2O + Cs = explose

Cs或Rb加入水都會爆炸,,仲要好勁...或者將K加入酸,呢個可能仲勁,,

但係學校係唔比做呢個實驗的(太危險=.=)...所以唔知有幾勁...

Cs+H2O -> CsOH + H+
唔知有無寫錯呢
