What happens when magnesium burns? What do you need for magnesium to burn? Will magnesium burn if you have it in a closed container? No. Why not? It needs air. Why does it need air? There is oxygen in the air. Magnesium needs oxygen to burn. So, when magnesium burns, you start with magnesium and end up with a compound that contains both magnesium and oxygen. Magnesium has an atomic weight of 24. Oxygen has an atomic weight of 16. So if you start out with 24 grams of Magnesium you should end up with 40 grams of Magnesium Oxide.

∙ 13y agoWhen magnesium burns it combines wtih oxygen to form magnesium oxide; this compound contains all of the original magnesium as well as oxygen, therefore the weight increases.

∙ 11y agoMg gets converted to MgO on combustion. Hence the weight is more after burning.

∙ 12y agoWhen the magnesium is burned then oxyen is added MgO so now the molar mass of magnesium is 24.31+16 becuase the magnesium stays just add the oxygen... hope it help!!
Wiki User
∙ 14y agoWhen magnesium burns it combines with oxygen to form magnesium oxide; this compound has more mass than the magnesium from which it was made, since the oxygen also has mass.
Wiki User
∙ 14y agoThe magnesium gets heavier when it is burned because it forms a new compound with oxygen in the air.
Wiki User
∙ 12y agoIt is because when magnesium burn in air,it react with oxygen in air to produce magnessium(iv)oxide.

What is the new substance when magnesium is burned?
Assuming Oxygen is the oxidizing element: 2Mg + O2 -> 2MgO + energy So your answer is MgO or Magnesium oxide or Magnesia
What does magnesium and sulphur make?
It makes Magnesium Sulphate
What is Mg3(PO4)2?
Magnesium Phosphide !
What metallic element is sometimes used in flares and flashbulbs?
Magnesium.
What compound is magnesium and oxygen make?
This compound is magnesium oxide - MgO.
What did William Crookes conclude from his experiment?
Priestley and Lavoisier discovered oxygen. I think they burned magnesium and it got heavier. The phlogiston theory (the theory that people believed about burning and combustion) could not answer this so they had discovered something. We now know that oxygen from the air is "extracted" when the magnesium is burned. the oxygen then combines with the magnesium and form magnesium oxide. So if you started with 24g of magnesium and burned it, you would end up with about 40g of magnesium oxide.
What becomes heavier after getting burnt?
Magnesium becomes heavier after it is burnt. This is because the magnesium has chemically bonded with oxygen to form magnesium oxide. The oxygen adds the extra weight.
What is the chemical name for the white powder formed when magnesium burned in air?
Magnesium oxide anything that is burned with oxygen (what is left) is called [material you burned] oxide
Why shouldn't magnesium be burned in pure oxygen?
magnesium should not be burned in pure oxygen because the flame will be white or luminous.
What chemical compound is formed when magnesium is burned?
Magnesium oxide?
When magnesium is burned in air what is the name of the new compound which is formed?
magnesium oxide magnesium oxide
What color is magnesium after it is burned?
white.
Is magnesium oxide heavier than water?
no
In what way are magnesium-24 and magnesium-25 different?
magnesium-25 is "heavier", it has one more neutron in the nucleus
When magnesium is burned in air is the product formed heavier lighter or the same mass as the magnesium that you started with?
Both products MgO (magnesium oxide) and some Mg3N2 (magnesium nitride)are both much heavier than the originating Mg strip before it was set to fire.Mg = 12 g/molMgO = (12+16) = 28 g/mol(1/3)Mg3N2 = (1/3)*(3*12 + 2*14) = 0.33*64 = 21 g/mol
How does nitrogen gas react with magnesium?
Magnesium nitride is formed when magnesium powder is burned in the presence of nitrogen gas.
What are the various grades of magnesium oxide?
Magnesium oxide is categorized as a refractory material, which means that it is resistant to decomposition by heat, pressure or chemical attack and retains strength and form at higher temperatures.Rahul Magnesia Pvt. Ltd. is one of the leading manufacturer and supplier of magnesium oxide from India. The company also deals with exports of calcined magnesium oxide, magnesium sulphate, magnesium chloride, magnesium carbonate and light magnesium oxide.Light Burned Magnesium OxideLight burned magnesium oxide is a reactive grade of magnesium oxide that has been calcined at temperatures ranging from 700ºC – 1000ºC. Rahul Mag’s high purity light burned magnesium oxide products have a wide range of reactivity and are used in various applications.Hard burned Magnesium OxideHard burned magnesium oxide is a low reactive grade of magnesium oxide that has been calcined at temperatures ranging from 1000ºC – 1500ºC. Due to its narrow range of reactivity, hard burned magnesium oxide is typically used in applications where slow degradation or chemical reactivity is required.Dead Burned MgODead burned magnesium oxide has been calcined at temperatures ranging from 1500ºC – 2000ºC in a high temperature shaft kiln yielding a material with very little reactivity. Dead Burned Magnesium Oxide products are high purity, dead burned magnesium oxides with high density and low reactivity.Specialty MgOSpecialty magnesium oxides are manufactured to precise specifications in chemistry, size and surface area. Specialty high surface area magnesium oxides are calcined at temperatures below 700°C to produce highly reactive magnesium oxides for use in specialty applications.
