A sample of iron weighs more after it rusts because:A. Rust contains twice as many iron atoms
B. Wrong. Iron actually weighs less after it rusts
C. It has expanded into a greater volume
D. Of the additional oxygen it contains
Final answer:A sample ofiron weighsmore after it rusts because:. Of the additional oxygen it containsThe answer is DExplanation:The weight of iron increases after it rusts due to the incorporation ofoxygen atomsin the corrosion process.Rust is iron(III) oxide, or Fe2O3, meaning the iron atoms have combined with oxygen atoms from the air. Let's clarify the options given:A. Rust does not contain twice as many iron atoms, it contains oxygen atoms combined with the iron.B. Iron does not weigh less after it rusts, the weight increases because of the additional oxygen.C. It's true that rust occupies a greater volume than iron metal because of its porous nature, but this does not impact the weight significantly.D. The correct answer is D. The additional weight is due to the additional oxygen that the iron has combined with during therusting process.The answer is DLearn more aboutRusting of Ironhere:brainly.com/question/18376414#SPJ11...
