Quick Answer: Can Fire Exist Without Oxygen?

What happens if you burn hydrogen?

In a flame of pure hydrogen gas, burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases energy.

If carried out in atmospheric air instead of pure oxygen, as is usually the case, hydrogen combustion may yield small amounts of nitrogen oxides, along with the water vapor..

Is hydrogen fuel the future?

The green hydrogen is the fuel of the future. AleaSoft, January 21, 2020. The hydrogen will be the fuel of the future and step by step it will replace all current fossil fuels.

Does the sun have oxygen to burn?

The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. … Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!

Does Sun have oxygen?

In our sun, hydrogen is fused to helium and the energy that’s released in this process is what makes the sun “glow” and emit energy. There is oxygen and many other elements on the Sun. … So, the Sun isn’t actually burning, hydrogen is fused to helium (without the need for oxygen).

Can milk put out a fire?

Milk and Grease Fires Some experts say milk also can cause a fireball or explosion when put on a grease fire. The only way milk can put out a grease fire is if such a vast quantity of milk is used that it completely submerges the fire, causing the fire to run out of oxygen.

What 3 things does a fire need?

Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

Can hydrogen be burned?

Hydrogen fuel is a zero-emission fuel burned with oxygen. … Since the weight of hydrogen is less than air, it rises in the atmosphere and is therefore rarely found in its pure form, H2. In a flame of pure hydrogen gas, burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases energy.

Why Hydrogen cars are a bad idea?

The sceptics’ first argument against hydrogen vehicles is that they’re less efficient than EVs are. Because hydrogen doesn’t occur naturally, it has to be extracted, then compressed in fuel tanks. It then has to mix with oxygen in a fuel cell stack to create electricity to power the car’s motors.

Can a normal car engine run on hydrogen?

There are two major problems with a hydrogen internal combustion engine. … Use hydrogen in a fuel cell to generate electricity. Fuel cells are far more efficient than internal combustion engines, and a hydrogen fuel cell has cleaner emissions than an internal-combustion hydrogen engine.

Can a gun fire in space?

Yes. Bullets carry their own oxidising agent in the explosive of the cartridge (which is sealed, anyway) so there’s no need for atmospheric oxygen to ignite the propellant.

What are the 4 types of fire?

Fire extinguishersClass A – fires involving solid materials such as wood, paper or textiles.Class B – fires involving flammable liquids such as petrol, diesel or oils.Class C – fires involving gases.Class D – fires involving metals.Class E – fires involving live electrical apparatus. (More items…

Do electrical fires need oxygen?

Turning off the electricity in an electrical fire removes the ignition source. … Without sufficient oxygen, a fire cannot begin, and it cannot continue. With a decreased oxygen concentration, the combustion process slows. Oxygen can be denied to a fire using a carbon dioxide fire extinguisher, a fire blanket or water.

How does fire burn in space without oxygen?

Combustion reaction is basically a reaction with oxygen. And we know that without oxygen, there is no combustion. … This is because the way the fuel burning takes place in a rocket is that they have their own oxygen because there isn’t any in the space. So how does fire burn in space?

Can magnesium burn without oxygen?

Without oxygen, the fire triangle is broken and the fire will go out. Magnesium is above carbon in the reactivity series and so can remove oxygen from carbon dioxide and continue to burn. Black specs of carbon can be seen to be ejected during the reaction.

Can you burn hydrogen without oxygen?

Burning (combustion) requires an oxidizer—but that oxidizer does not have to be oxygen. The halogens, for instance, oxidize things quite easily, and hydrogen burns in them with no trouble. It would even burn in sulfur vapor.

Do humans explode in space?

The vacuum of space will pull the air from your body. So if there’s air left in your lungs, they will rupture. Oxygen in the rest of your body will also expand. You’ll balloon up to twice your normal size, but you won’t explode.

Can you have combustion without oxygen Class 10?

It would not burn in the classical, combustion sense because as you noted, there is no oxygen present. Paper is a carbon-based material and so it requires oxygen to combust and form products like solid carbon, carbon dioxide, carbon monoxide, etc.. However, combustion is not the only thing that could happen here.

Can magnesium burn underwater?

In what way and in what form does magnesium react with water? Magnesium fires cannot be extinguished by water. Magnesium continues to burn after oxygen is depleted. … When attempts are made to extinguish magnesium fires with water, magnesium aggressively reacts with hydrogen gas.

Why does magnesium burn skin?

“Your skin will easily absorb it and deliver much-needed magnesium to your bloodstream and cells. … “If your body’s cellular magnesium levels are low and you apply magnesium oil directly onto your skin, it may sometimes sting a little, she says. “Over time and with gradual use, this sensation usually decreases.”

Can fire burn underwater?

Regular fire, i.e. wood or paper burning – no. Because there isn’t enough oxygen to start or sustain regular combustion. But there are kinds of combustion which work underwater. … You can light a strip of magnesium, and the combustion actually produces oxygen, which is then used to sustain the combustion.

Why is magnesium heavier when burned?

When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. … Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide.
