Is oxygen lighter than helium?
no. If it was, we would have oxygen balloons instead of helium balloons.
Is rust stronger than iron?
It depends on what you mean by "heavier." Rust is less dense than iron. However, if you allow 1 gram of iron to rust completely, you will have more than 1 gram of rust. if we have equal volume of pure iron and rust (ferric oxide) then rust is lighter than iron.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
What happens when two nuclei that are heavier than iron are fused?
The two nuclei's are lighter than iron then when they are fused together they will release energy. If the two nuclei's are heavier than iron they will absorb energy when fused.
Why does rust weigh more than original powdered iron?
When iron (Fe) rusts, it combines with oxygen (O2) to form various forms of iron oxide such as Fe2O3, Fe3O4, or FeO2. In each of these there are oxygen molecules bonded to the iron. The oxygen comes from the air, water or other solution. So an object which was formally pure iron, once rusted, will contain additional mass from the oxygen and weigh more than it did before.
What is lighter oxygen or nitrogen?
Nitrogen is lighter than oxygen
Is carbon dioxide lighter than oxygen?
carbon dioxide is heavier than oxygen therefore oxygen is lighter.
Is neon heavier than iron?
No. Neon is lighter than iron
Is lithium is lighter than iron?
yes lithium is lighter than iron by just a mere look at their atomic masses.
Why is it that the nitrogen have greater amount than oxygen?
nitrogen is lighter than oxygen
Is iron heavier or lighter than aluninum?
Iron is more dense.
Will oxygen sink or float?
In what? Oxygen is much lighter than water.
Is there anything lighter than oxygen?
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
Is oxygen lighter than helium?
no. If it was, we would have oxygen balloons instead of helium balloons.
Is ductile iron lighter than grey iron?
They are virtually identical with very similar densities.
Why iron floats on water?
Iron doesn't float. To float it has to be lighter than water. It is heavier.
Why is aliminium better than iron for airplanes?
Aluminium is way lighter than iron, and therefore the plane can get off the ground.
