Why is a mass bigger if magnesium is burned in oxygen?
When magnesium is burned in oxygen, it undergoes a chemical reaction called combustion. During this reaction, magnesium atoms combine with oxygen atoms to form magnesium oxide. The increased mass observed after burning magnesium is due to the formation of magnesium oxide, which adds the combined mass of magnesium and oxygen atoms to the initial mass of the magnesium.
What 4 elements make up 95 percent of the earth's mass?
The four elements that make up 95 percent of the Earth's mass are oxygen, silicon, iron, and magnesium. These elements are abundant in the Earth's crust and core, contributing to its overall composition.
Do iron and magnesium oxide react chemically?
Iron and magnesium oxide can react chemically to form iron(II) oxide and magnesium metal. The reaction occurs when iron is heated with magnesium oxide in a high temperature environment, leading to the transfer of oxygen from magnesium oxide to iron.
HOW TO GET percent of magnesium by mass?
To calculate the percentage of magnesium by mass in a compound, divide the mass of magnesium by the total mass of the compound, then multiply by 100. Percentage of magnesium by mass = (mass of magnesium / total mass of compound) * 100.
What does magnesium and iron chloride make?
most likely Magnesium-Chloride(MG?CL?) and Iron(FE?) The numbers depend on the oxidation states of iron and magnesium
Would magnesium and iron nitrate react?
No, as magnesium is more reactive, and would 'keep' the nitrate.
What is the name of the metal that has the mass of 46.4 and a volume of 2.40?
Magnesium-Aluminum Alloy
Is iron or magnesium more reactive?
Magnesium is more reactive than iron. Magnesium reacts more readily with oxygen and water to form compounds like magnesium oxide and magnesium hydroxide compared to iron.
Does magnesium react with iron chloride?
yes! it does because magnesium is higher in reactivity series than iron , so the magnesium atom would displace or push out the iron atom from the compound and join with chloride, leaving the pure iron out of the compound Mg + FeCl2 -- MgCl2 + Fe
Why does the iron rusts when magnesium is put in the water with the iron?
When magnesium is put in water with iron, the magnesium acts as a sacrificial anode due to its higher reactivity. This causes the magnesium to corrode instead of the iron, protecting the iron from rusting. This process is known as cathodic protection.
What is the ratio of magnesium oxide mass to the magnesium mass?
.659
What is the reaction of iron and magnesium sulphate?
Fe + MgSO4 --> FeSO4 + Mg Fe(iron)is more reactive than mg( magnesium) ........ therefore iron will displace magnesium....... hence it is a displacement reaction.............
