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!! :)

∙ 14y agoIt is because the magnesium has combined with the oxygen, and believe it or not oxygen actually has a weight, so the weight of the magnesium increases as it now has some oxygen molecules.

Is Nitrous Oxide lighter or heavier than air?
Nitrous Oxide is heavier than air.
When magnesium metal is burned in the presence of oxygen magnesium oxide are different than the individual properties of magnesium and oxygen because magnesium oxide is?
It is a compound.
What relationships are there between magnesium and magnesium oxide?
Magnesium is an element. Magnesium oxide is a compound formed from magnesium and oxygen. Magnesium oxide often serves as a magnesium supplement.
How and why does the mass of a magnesium strip change when it is heated strongly in air?
When a magnesium strip is heated strongly in air, it undergoes a chemical reaction called oxidation. Magnesium reacts with oxygen in the air to form magnesium oxide. The mass of the strip increases because magnesium combines with oxygen atoms from the air to form a heavier compound (magnesium oxide).
Does magnesium react?
Magnesium reacts with steam faster than cold water because magnesium needs to burn to get magnesium oxide and to get magnesium oxide there has to be heat and since steam is already heated it doesn't need much time, but the cold water needs time to heat first to react.
Is magnesium oxide heavier than water?
no
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.
Is Nitrous Oxide lighter or heavier than air?
Nitrous Oxide is heavier than air.
What is the common name for MgO?
Magnesium Oxide
When magnesium metal is burned in the presence of oxygen magnesium oxide are different than the individual properties of magnesium and oxygen because magnesium oxide is?
It is a compound.
What compound is magnesium and oxygen make?
This compound is magnesium oxide - MgO.
When you heat copper oxide and magnesium why do you get grey powder?
You get a grey powder because magnesium is higher up in the reactivity series than Copper - (magnesium is more reactive than copper) therefore when you heat it up there is a displacement reaction. That grey powder is actully magnesium oxide and copper e.g Copper oxide + magnesium = magnesium oxide and copper.
Is Mgo a compound or element?
MgO is a compound because it has more than one type of element in it, magnesium and oxygen.
What does magnesium and copper oxide make?
Magnesium + copper oxide --> magnesium oxide + copper
What relationships are there between magnesium and magnesium oxide?
Magnesium is an element. Magnesium oxide is a compound formed from magnesium and oxygen. Magnesium oxide often serves as a magnesium supplement.
What atoms are in magnesium oxide?
Magnesium oxide contains magnesium and oxygen.
