Is there a chemical that burns or explodes in water?

Answer 1

Sodium reacts with water to make sodium hydroxide base and hydrogen gas [Na(s) + H2O(l) --> NaOH(aq) + H2(g) + heat]. The reaction is exothermic, which is enough to cause the flammable hydrogen gas to ignite explosively with oxygen in the atmosphere to make new water molecules [2H2(g) + O2(g) --> 2H2O(g)]. For these reasons, sodium is usually kept under mineral oil to keep it from reacting with these common substances

Answer 2

Sodium, lithium and potassium are a few.

They don't technically burn I suppose, they just become a more unstable substance when they combine with the hydrogen in the water.

That guy's right about salt, it doesn't mix as easily with water cuz the sodium's already bound to chlorine.

Answer 3

yes
Hydrogen - 1
lithium - 3
Sodium - 11
Potassium - 19
Rubidium - 37
Caesium - 55
Francium - 87
All have a violent reaction when exposed to water. The larger the number the more violent the reaction.
Francium, Rubidium, and Caesium are so violent that they are rare to the point of almost non existance due to the abundance of water in our atmosphere.

Answer 4

I believe sodium burns when it gets wet. Not salt because sodium is combined with other things to make salt. Straight sodium will explode.

Answer 5

go with francium. It will make the biggest explosion ou of all the chemicals that you put in water. This element is radio active s it will be very difficult to find it.

Answer 6

I think sodium reacts to water, also lithium and potassium do if I recall correctly.

Answer 7

any of the group 1A alkali metals, are metals that react violently with water.
the farther down the periodic chart they are, the more violent the reaction will be.

Answer 8

Yes, there is even an underwater torch.

Answer 9

is it sulphur... maybe sodium... i can't remember

I know that there is something that you put in water that will blow up...

but I'm an Arts major...

Answer 10

napalm
