What chemicals when mixed cause fire?

Answer 1

Concentrated nitric acid and glacial acetic acid...careful!!

Answer 2

I once went through the entire CRC handbook of chemistry and physics, and listed everything that was explosive. They were much more rare than things that were flammable. Even though they were rare... the list was long. My point: if you are looking for potential ingredients there are thousands of them. Its a long list.

You should ask yourself some questions to more meaningfully refine the list:

What chemicals when mixed cause fire
AND are controllable
AND have predictable behavior
AND dont poison me, someone else, or the world
AND are reasonably commercially available
AND arent unreasonably corrosive
AND are relevant to my application
AND work in my operational environment

When clarify what predictable, reasonable, and relevant are then you can re-ask the question and expect meaningful specific answers.

Answer 3

Potassium Perchlorate and Aluminum (600-800 mesh). If you mix enough you will have instintaneous combustion and you don't want to be anywhere near it.

Answer 4

The previous post, though researched extensively, is still purely theory, experiments are expected to take place soon, I expect explosive results.

Answer 5

the class of materials called hypergolics auto-ignite on contact. they are used in the shuttle for the attitude thrusters and were used on the ascent stage of the apollo lander. can be various combinations of materials.

Answer 6

Things like Columbine result from answering this question.

Answer 7

Chlorine gas and Hydrogen gas, when expossed to light

Answer 8

Sulfer and Oxygen, you still need a katalyst.

Answer 9

Water and sodium metal

Answer 10

Oxygen,Heat,& Fuel. Hope this helps.
