Ch. 2 & 3 Questions Bio105 – Introductory Biology Online The following questions can be found in your text book. After answering the questions, save this document to your computer and submit it under the Chemistry Assignment link in your online class. Questions from page 41 1. In the Middle Ages, alchemists labored to turn common materials such as iron, into precious metals like gold. If you could journey back in time, how could you convince an alchemist that iron cannot be changed into gold. Iron can’t be changed into gold. Gold is made up by a collision of dead stars, each element is pure and has a different amount of protons. Iron is made within a star, hydrogen and helium fuse using energy between them which causes a supernova. To turn Iron into Gold you would have to change the number of protons to change the element, but no chemical is capable of that. To be able to do that you would need huge amounts of energy to be able to alter the protons.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
