it would be a chemical reaction
mArKe ^_^
No, it is a chemical process.
The Nitroglycerin breaks down into water vapor, carbon dioxide, nitrogen, and oxygen.
Chemical
Dynamite's active ingredient is nitroglycerin (the rest is just to stabilize the nitroglycerin); in the explosion, the nitroglycerin reacts thus; C3H5(NO3)3 → 3CO2 + 2.5H2O + 1.5N2 + 0.25O2 so YES its a chemical reaction.
An atomic bomb uses fission-- the splitting of atoms. It is purely a physical change, at first. Any gases produced in the air surrounding the explosion (which occurs before it touches the ground), along with the intense heat produced, causes chemical changes in the air.
water boils, it make sound. is that a chemical change??? P.S why use wikianswer?
A physical change
An explosion is the sudden release of a volume of compressed gas. The chemicals remain the same, so it is only a physical change.Note that the reaction resulting in an explosion may be a chemical change, but the resulting pressure changes are not.
it is a chemical change
chemical
This is a chemical change.
the physical comes from the chemical explosion
Chemical, an explosion is essentially extremely fast combustion which is a chemical reaction.
Dynamite's active ingredient is nitroglycerin (the rest is just to stabilize the nitroglycerin); in the explosion, the nitroglycerin reacts thus; C3H5(NO3)3 → 3CO2 + 2.5H2O + 1.5N2 + 0.25O2 so YES its a chemical reaction.
Explosiveness (not oxploziveness!) is a property, not a change. But it is a chemical property.
It is usually a chemical change.
Yes, the combustion of the components of dynamite (nitrate sensitized with nitroglycerin absorbed on wood pulp) results in an irreversible (2nd law of thermodynamics) exothermic process, thus we have a chemical change. Sincerely, -- Jordan D. Ulmer
A chemical reaction occurs but this is a physical change since it can't be reversed.
An explosion is an example of a chemical change because the arrangement of the atoms has been altered.
A physical change stays the same like tearing paper A chemical change makes the substance something new like fireworks explode (fireworks change to explosion)
