When a match burns, its mass decreases. Why does a sample of iron weighs more than after it rusts? Do these observations violate the law of conservation of mass? B) rust contains twice as many iron atoms. It is now iron oxide.
C) of the additional oxygen it contains. Oxygen atoms are used to make water molecules. When iron is exposed to oxygen and water, it undergoes a chemical reaction known as oxidation, which results in the formation of iron oxide. Rust contains twice as many iron atoms.
Rust contains twice as many iron atoms. When iron nails rust, should their mass increase, decrease, or remain the same? A) it has expanded into a greater volume.
Do these observations violate the law of conservation of mass? A sample of iron weighs more after it rusts because. It has expanded into a greater volume. Web a sample of iron weighs more after it rusts because:. The chemical reaction can be represented as follows:
Web when iron rusts, a compound forms with the formula $\mathrm{fe}_{2} \mathrm{o}_{3}$. Iron (fe) reacts with oxygen (o2) in the presence of water (h2o) to form iron oxide (fe2o3), which is commonly known as rust. It is now iron oxide.
C) Of The Additional Oxygen It Contains.
Rust contains twice as many iron atoms. To answer this question, we need to balance chemical reaction iron when it rusts, it combines with oxygen to make iron three oxide with this balanced chemical reaction and the law of conserved mass. It has expanded into a greater volume. When an iron object rusts, its mass increases.
Rust Is Iron(Iii) Oxide, Or Fe2O3, Meaning The Iron Atoms Have Combined With Oxygen Atoms From The Air.
A baby because this is surely a trick question. Chemical change involving the formation of ions. Rust contains twice as many iron atoms. Web a sample of iron weighs more after it rusts because.
It Has Expanded Into A Greater Volume.
Rust contains twice as many iron atoms. Web the iron reacts with water and oxygen to form hydrated iron (iii) oxide, which we see as rust. Web when iron rusts, a compound forms with the formula $\mathrm{fe}_{2} \mathrm{o}_{3}$. Matter and transformation of matter.
A Sample Of Iron Weighs More After It Rusts Because Select One:
Of the additional oxygen it contains. That's because we have a combination reaction here where we get iron 3 oxide. So that would be fe2o3 because rusting is oxidation, which means the iron is combining with oxygen from the air. B) rust contains twice as many iron atoms.
Therefore, the correct answer is: Web a sample of iron weighs more after it rusts because a) it has expanded into a greater volume. That's because we have a combination reaction here where we get iron 3 oxide. Rust contains twice as many iron atoms. 4fe + 3o2 + 6h2o → 4fe (oh)3 → 2fe2o3·3h2o.
