Can hydrogen put out fire?
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 Colour is the flame of hydrogen burning?
pale blueOxygen (or air) and an ignition source are required for combustion to occur. Hydrogen burns with a pale blue flame that is nearly invisible in daylight. The flame may appear yellow if there are impurities in the air like dust or sodium.
Does magnesium burn with a flame Why?
Magnesium burns so bright because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide (MgO). In the sequence shown here, a person places a piece of magnesium metal in an alcohol stove flame.
What happens when magnesium ribbon is burnt?
The burning magnesium ribbon produces light of sufficient intensity to cause temporary loss of sight. Avoid looking directly at the light source. The burning of magnesium in air produces intense heat which can cause burns and initiate combustion in flammable materials.

What is the white smoke from burning magnesium?
Normally one demonstrates magnesium burning by getting it started in the Bunsen flame, and then removing it so that it burns in air with a blinding white light. The product is a white smoke. This product can be collected by burning the magnesium under an inverted beaker, showing it is a solid, a white ash — MgO.
Does magnesium burn hotter with ice?
He also notes that ice makes magnesium burn hotter. … Water is among the compounds that reacts with magnesium when it burns, increasing the reaction and turning magnesium and water into hydrogen and magnesium oxide.
What does magnesium look like after burning?
Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.
What metal can burn?
Iron and titanium are examples of such metals. If, as with zirconium, the metal has a high boiling point and possesses a refractory oxide, a solid oxide film, which slows the reaction, can be formed on the metal surface. Metals such as molybdenum, which form oxides that readily sublime burn at the surface of the metal.
How fast does magnesium burn?
Flammability. Magnesium is highly flammable, especially when powdered or shaved into thin strips, though it is difficult to ignite in mass or bulk. Flame temperatures of magnesium and magnesium alloys can reach 3,100 °C (5,610 °F), although flame height above the burning metal is usually less than 300 mm (12 in).
How does magnesium burn underwater?
Magnesium reacts with water to produce hydrogen and a lot of heat. Yes, magnesium will burn underwater by burning the hydrogen gas it produces when reacting with the water. Magnesium reacts violently with water and several different sources of oxygen in the air.
Does magnesium burn with a flame?
Magnesium burns with a bright, white flame. Magnesium gets very hot when it burns. Some fire extinguishers use carbon dioxide to put out fires.
Why does hydrogen burn with a blue flame?
The blueness so frequently associated with the flame of hydrogen is really due to the presence of sulphur as is shown in a little paper I published in the Philosophical Magazine for November 1865.
Can magnesium burn through metal?
Often, strips of magnesium metal are used as fuses. Because metals burn without releasing cooling gases, they can potentially burn at extremely high temperatures. Reactive metals such as magnesium can easily reach temperatures sufficiently high for thermite ignition.
Does charcoal form flame on burning?
The substances which vapourise during burning, give flames. For example, kerosene oil and molten wax rise through the wick and are vapourised during burning and form flames. Charcoal, on the other hand, does not vapourise and so does not produce a flame.
Why should a magnesium ribbon be cleaned before burning?
Magnesium ribbon should be cleaned with sandpaper before burning in the air. … To remove the Magnesium oxide layer from the ribbon which may prevent or slow down the burning of magnesium ribbon. Unwanted impurities deposited on the magnesium ribbon can be removed and only pure magnesium can be used for the reaction.
Which gas burns with a blue flame?
With complete combustion, methane burns with a blue flame color (natural gas blue flame) and burns at a temperature of around 1,960°C.
