What causes fire when mixed with water?
Hydrogen is flammable, but oxygen is not. When hydrogen combines with oxygen the result is water, where the atoms of hydrogen and oxygen are linked together to make a molecule with entirely different properties. You can’t burn pure water, which is why we use it to put out fires instead of starting them.
What chemicals make fire when mixed?
When potassium chlorate and ordinary table sugar are combined, and a drop of sulfuric acid is added as a catalyst, the two react violently with each other, releasing large quantities of heat energy, a spectacular purplish flame, and a great deal of smoke.
What chemical ignites on contact with water?
Water reactive chemicals are chemicals that react vigorously with moisture. The most common water sensitive chemicals include sodium, potassium, lithium metals and aluminum alkyls.
What is the chemical equation for fire?
As long as there is enough fuel and oxygen, the fire keeps burning. Fuel + oxygen (from the air) = combustion products (mainly CO2 + H2O) + heat energy.
What chemically reacts with water?
Water-reactive substances are those that spontaneously undergo a chemical reaction with water, as they are highly reducing in nature. Notable examples include alkali metals, sodium through caesium, and alkaline earth metals, magnesium through barium.
What is the chemical makeup of water?
A water molecule is made up of two hydrogen atoms and one oxygen atom. A single oxygen atom contains six electrons in its outer shell, which can hold a total of eight electrons. When two hydrogen atoms are bound to an oxygen atom, the outer electron shell of oxygen is filled.
What is the chemical composition of water?

What chemicals create fire?
Answer: Fire is the result of a chemical reaction, called combustion. At a certain point in the combustion reaction, called the ignition point, flames are produced. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen.
Which alkali metal will explode in water?
Any of the alkali metals (the first group in the periodic table) will react pretty violently with water and cause a fire or explosion. The further down the group you go the more violent the reaction so some will cause a brief fire and some will just explode instantly. Caesium (Cs) will c…
Why does water put out a fire?
When water extinguishes a fire, it does so because it doesn’t break down into its constituent elements. The water molecule doesn’t become hot enough to separate into hydrogen and oxygen and instead, has two potential actions on the fire that can put it out.
What is the best element that can explode on water?
The further down the group you go the more violent the reaction so some will cause a brief fire and some will just explode instantly. So sodium, potassium and rubidium would be your best bet at making a brief fire on water with the extremely small possibility of francium.
