No, iron is not lighter than oxygen. Iron has a density of about 7.87 grams per cubic centimeter, while oxygen, in its gaseous state at standard temperature and pressure, has a density of about 0.00143 grams per cubic centimeter. This means that iron is significantly denser and heavier than oxygen.
No, when 100g of iron reacts with oxygen to form iron oxide, the resulting compound will have a different mass than the initial iron due to the addition of oxygen atoms. The mass of the iron oxide formed will be greater than 100g, as the oxygen atoms combine with the iron atoms to form the compound.
When iron is burnt, it combines with oxygen to form iron oxide (rust). This increase in weight is due to the added oxygen atoms bonded to the iron atoms, making the total weight of the iron and oxygen combined greater than that of the unburnt iron alone.
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.
Rust is iron oxide, which is made up of iron and oxygen atoms. When iron reacts with oxygen to form rust, it increases in weight because it has gained oxygen atoms. This increase in weight is why rust weighs more than the original powdered iron.
Helium is classified as a light element because it has a low atomic mass compared to other elements like oxygen or iron. It is lighter than air, which is why helium-filled balloons float.
No. Neon is lighter than iron
Nitrogen is lighter than oxygen. The atomic weight of nitrogen is approximately 14, while the atomic weight of oxygen is approximately 16.
Iron is more dense.
nitrogen is lighter than oxygen
In what? Oxygen is much lighter than water.
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
They are virtually identical with very similar densities.
Aluminium is way lighter than iron, and therefore the plane can get off the ground.
The core contains more iron than the crust. The outer core of the Earth is mainly composed of iron and nickel alloy, while the crust is made up of lighter elements like silicon, oxygen, and aluminum.
yes at ATM and temp
Steel was lighter, cheaper, and stronger than iron, allowing for constructions and technologies that were impossible before. Steel was important to Second Industrial Revolution because it was much lighter compared to iron. --------------- It was cheaper than iron.
A compound is not lighter than an element, if that element is part of the compound. Some compounds, like H2O would be lighter than, say, the element lead, but it is not lighter than the elements that make it up, i.e. hydgrogen and/or oxygen.
