One molecule of oxygen will react with one molecule of hydrogen to produce one molecule of hydrogen peroxide: H2 + O2 --> H2O2 One half molecule of oxygen will react with one molecule of hydrogen to produce one molecule of water: H2 + ½O2 --> H2O ...but nobody would write it like that. It is more correct as follows: 2H2 + O2 --> 2H2O

∙ 13y agoMagnesium reacts with Oxygen forming Magnesium Oxide:
Mg + (1/2) O2 --> MgO.
From the reaction equation one can see one magnesium atom reacts with one oxygen atom. As you have 5 million oxygen molecules (O2), you have 10 million oxygen atoms. Therefore, 10 million magnesium atoms can react with it.

What is the gas that reacts with calcium and magnesium when they burn?
Hydrogen gas is released when calcium and water react.
Is argon or magnesium more reactive with oxygen?
Argon is a Non-Reactive Element. Magnesium is a very Reactive Element. Magnesium will react violently when ignited in an Oxygen rich environment.
How many molecules of oxgen are needed to react 100 atoms with all the magnesium?
50
What type of bonds are formed when calcium atoms react with oxygen atoms?
Ionic ponds.
What is the result on mixing a water molecule and a oxygen molecule together?
If oxygen combines with water, the result is hydrogen peroxide. Of course, the oxygen does not necessarily react. You can also just get water with dissolved oxygen.
How many magnesium atoms would be needed to react with one bromine molecule?
Two magnesium atoms.
Why magnesiam oxide is not attacked by atmospheric oxygen?
The magnesium has reacted already with as much oxygen that it can (1 atom of oxygen to 1 atom of magnesium). There are no spare magnesium atoms left so the reaction has stopped, There is no energetically favourable way that further oxygen atoms can react.
How many moles of magnesium oxide are formed when 4 moles of magnesium react with oxygen Here is the formula 2 Mg plus O 2 is equal to 2 Mg O?
From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.
When oxygen was first released it was combined with iron to form?
When two oxygen atoms react together they form an oxygen molecule (O2).
How many atoms of carbon react with a molecule of oxygen to form a molecule of carbon monoxide?
there is one atom of oxygen in Carbon monoxide (CO) i.e. half molecule of oxygen.
What do you get when you react magnesium wth oxygen and heat?
magnesium oxide (MgO)
What is the reaction if magnesium react with oxygen?
Nothing :0
What does magnesium react with when burnt?
Oxygen in the air (O2)
What do atoms do when they react with other atoms?
They form a molecule by the intermediate of chemical bonds.
How many chlorine atoms are in MgCl2?
Three. Two chlorine atoms and one magnesium atom.
Metal that burns bright in oxygen but does not react with water?
Magnesium.
What ozone is and what cfcs do?
Ozone is a molecule with formula O3. It is bent in shape and has sp and sp2 hybridised oxygen atoms. Chlorofluorocarbons are compunds of carbon and fluorine. They react with ozone to form oxygen.
