Such substances are called pyrophoric. Most are actually igniting in response to water vapour in the air, but it doesn't necessarily have to be that humid for them to start burning.
On the list are,
* iron sulfide;
* depleted uranium (if sliced thinly or powdered);
* other finely divided metals (including magnesium, calcium, zirconium)
* Aakali metals (sodium, potassium)
* metal hydrides or nonmetal hydrides (germane, diborane, sodium hydride, lithium aluminum hydride, uranium trihydride)
* grignard reagents (compounds of the form RMgX)
* fully or partially alkylated hydride derivatives(e.g., diethylaluminum hydride, trimethylaluminium, butyllithium, triethylboron)
* alkylated metal alkoxides
* nonmetal halides (diethylethoxyaluminum, dichloro(methyl)silane)
* metal carbonyls (iron pentacarbonyl, dicobalt octacarbonyl, nickel carbonyl)
* used hydrogenation catalysts, including Raney nickel (very volatile because of extra hydrogen already attached to it)
* phosphorus (white, yellow)
* plutonium
* methanetellurol (CH3TeH))
Some gases are prone to such combustion, including * Arsine, Diborane, Phosphine, Silane, and the liquid hydrazine. Also metalorganic liquids.
Some types of coal, caseium rubidium, silanes, and boiled linseed oil can also ignite when just exposed to ordinary air.
What else can I help you with?
What causes carbonite to explode?
Carbonite explodes because the mixture of ingredients are volatile and when exposed to to something like fire with be set off. It is commonly used in the mining industry.
What does flamability mean?
something that catches on fire.
Why does petrol catches fire easily?
Petrol catches fire easily because it is a highly flammable liquid that evaporates quickly at room temperature, creating a mixture of vapor and air that is easily ignitable. Additionally, petrol has a low flash point, which is the temperature at which it can produce enough vapor to ignite when exposed to a flame. These factors make petrol highly flammable and pose a fire risk.
Why does potassium sink in water?
K catches fire in water .
Is flammability a physical or a chemical?
Flammability is considered to be a chemical and not a physical change. This based on the fact that combustion will take place which is a chemical reaction.
What is the flamability of sodium?
It readily catches fire when exposed to oxygen.
If a pickup truck catches fire in the engine will the truck explode when the fire gets to the gas tank?
No. A fuel tank will not explode just because it is on fire. However, it will feed the fire and make it worse.
Can a limestone fire pit explode when exposed to high temperatures?
Yes, a limestone fire pit can potentially explode when exposed to high temperatures due to the risk of thermal shock caused by rapid heating and cooling.
What is used in fire grenades?
White phosphorus, it is a chemical that catches fire on contact with oxygen.
Do river rocks explode when exposed to fire?
Yes, river rocks can explode when exposed to fire. This is because the rocks may contain trapped water or other substances that expand rapidly when heated, causing the rock to break apart.
Will rocks explode in fire?
Rocks do not typically explode in fire. However, some rocks, like certain types of volcanic rocks, can explode when exposed to extreme heat due to trapped gases or water vapor inside them.
How does a fire start?
when a flammable chemical such as oil (ancient tree) gets heated up to much it acts as a chemical reaction it catches on fire
How do river rocks react when exposed to extreme heat, such as exploding in fire?
River rocks can explode when exposed to extreme heat, such as in a fire, due to the expansion of water trapped inside the rocks.
What is the statement methane as a gas that easily catches fire describe?
The statement "methane as a gas that easily catches fire" means that methane is highly flammable and can ignite easily when exposed to a flame or spark. This characteristic makes it a significant fire hazard if not handled properly, as it can lead to explosions or fires.
What is the property that describes how easily a substance catches fire and burn?
The property that describes how easily a substance catches fire and burns is called flammability. It measures the ability of a material to ignite and sustain combustion when exposed to a heat source.
Which types of rocks explode when exposed to fire?
Certain types of rocks, such as sedimentary rocks like limestone and shale, can explode when exposed to fire due to the presence of trapped gases or water within the rock. These rocks can fracture and break apart when heated rapidly, leading to explosive reactions.
Can a river rock fire pit explode?
Yes, a river rock fire pit can potentially explode if the rocks are porous and absorb moisture, which can cause them to crack or shatter when exposed to high heat. It is important to use rocks that are heat-resistant and not prone to exploding when building a fire pit.
