5. A chemist observes that the iron fence outside his home has changed color and texture over time. Which would be a testable scientific question the scientist could ask? (2.5 Points) What will my neighbors think of me if I do not replace the fence? What could I have done to prevent the fence from changing color and texture? Will my friends think the fence is ugly? Which looks better, an iron fence or a wooden fence?

What could have possibly turned the iron fence into a different texture and  color. What chemical reaction has taken place in order to change the texture and color of the iron fence? If you live in a wealthy neighborhood, then chances are, they might think it looks lazy. Weather, Rainstorms, and high humidity cause iron fences to rust. You can probably repaint the fence a different color. As long as your friends aren't harsh with you, I don't think they'll think it's ugly. I would prefer a wooden fence and then repaint it from there.
