Answer 2

The correct answer is D, less than the nail it came from because the nail flakes away. Rust is a corrosion product that forms on iron as a result of a reaction between iron and moisture in the air.

Over time, the rust can flake off from the iron nail, reducing its overall weight. Although the rust is heavier than the iron it formed from, the amount of weight loss from the iron nail may not be significant, and may not be easily noticeable without precise measurements. However, the loss of iron due to the formation of rust can weaken the structure of the nail, making it more prone to breaking. It's important to note that rusting can have a significant impact on the durability and longevity of iron objects, especially when exposed to moist or corrosive environments. To prevent rusting and extend the lifespan of iron objects, various protective coatings or rust inhibitors can be applied.
