rust results from irons reaction to oxygen. an iron nail gains mass when it rusts. how does this reaction support the law of conservation of mass?\nthe mass of the rusted nail equals the mass of iron and the oxygen from the air it reacted with to form the rust.\nthe mass of the rusted nail increases because iron attracts more protons from the air.\nthe increased mass of the rusted nail is an exception to the law of conservation of mass since the rusted nails mass increases.\nthe increased mass of the rusted nail results from the rearrangement of protons and neutrons within oxygen, according to the law of conservation of mass.
Answer
Brief Explanations:
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. When iron rusts (reacts with oxygen), the mass of the rusted nail is the sum of the original iron mass and the mass of oxygen it reacted with. Protons are not attracted from the air in this process, it's not an exception to the law, and the mass increase isn't due to rearrangement of protons and neutrons in oxygen.
Answer:
The mass of the rusted nail equals the mass of iron and the oxygen from the air it reacted with to form the rust.
