Yes, the reaction between fluorine and radium can be violent. Fluorine is a highly reactive element, and when it comes into contact with radium, which is a radioactive metal, it can lead to a rapid and potentially explosive reaction releasing large amounts of energy.
no. But not all of runescape is violent. You can 'skill' which involves no violence at all.
Their reaction with the water is a purely chemical change, however the chemical reaction is so intense and violent that it is usually followed by many dangerous physical changes (e.g. boiling of the water, flinging molten pieces of the unreacted metal at you, spattering drops of lye solution at you).
Fire is a violent reaction of oxydation.
This reaction is:2 Na + 2 H2O = 2 NaOH + H2The reaction is very violent.
