Why does magnesium get heavier when its burned?

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.

In the reaction between magnesium and oxygen the mass of magnesium and oxygen was 2.5 grams how much magnesium oxide was formed?

340 grams

Which has the bigger mass iron or magnesium?

You mean density?

What happens when you magnesium is heated in air?

Magnesium's mass increases as it becomes magnesium oxide.

Magnesium oxide decomposes into magnesium and oxygen If 16.12 of magnesium oxide decomposes to form 9.72 of magnesium what mass of oxygen gas is also released in the reaction?


Magnesium oxide decomposes into magnesium and oxygen If 4.03 of magnesium oxide decomposes to form 2.43 of magnesium what mass of oxygen gas is also released in the reaction?

4.03g - 2.43g = 1.60g

Why is magnesium oxide heavier than magnesium?

Magnesium Oxide increases in mass because it is made of oxygen AND magnesium, and the symbol equation explains that 2MG (2 magnesium) + O2( 2 oxygen) makes 2MGO (2 Magnesium Oxide) because oxygen is a molecule as the 2 shows that for oxygen it is made up of 2 atoms, and to balance the equation magnesium must be 2 too, making 2 Magnesium Oxide ,this shows the mass increases as oxygen is ADDED to magnesium, thus making it heavier and an increase in mass. Ta-Da just amazing chemistry logic!! :)

What 4 elements make up 95 percent of the earth's mass?

Iron, Oxygen, Silicon, and Magnesium

Why does carbons mass go down when it is burned in oxygen?


What is the mass of 2.6 g of magnesium and 1.6 g of oxygen?

The molar mass of magnesium is 24.31 g/mol, while the molar mass of oxygen is 16 g/mol. To find the mass of 2.6 g of magnesium, you can divide 2.6 g by the molar mass of magnesium (24.31 g/mol) and multiply by Avogadro's number to find the number of moles. Similarly, you can do the same calculation for 1.6 g of oxygen and then sum up the molar masses to find the total mass.

Why does a magnesium ribbon burn with a dazzling white flame?

Magnesium undergoes a chemical reaction when it burns: It combines with oxygen out of the atmosphere to form magnesium oxide (MgO), which has more mass than the Mg alone. The atomic mass of magnesium is 24.3, but the molecular mass of MgO is 40.3 (24.3 + 16.0).

When carbon is burned in air it reacts with oxygen to form carbon dioxide When 12.0 of carbon were burned in the presence of 49.8 of oxygen 17.8 of oxygen remained unreacted What mass of carbon?
