Somewhere I heard about this chemistry test where the students (advanced level) are locked in the chem lab for a few days to even a week, they're given no food, and have nothing but the chemicals in the lab to survive? With a good enough understanding of chemistry, they should be able to mix different elements and compounds together to create organic compounds, proteins, fats, etc. Only water is unlimited, if even that. Has anyone heard about this before?

I've heard the Hubble telescope is big enough but the moon is to bright and so much light could damage the telescope. But maybe some lunar orbiters photographed Apollo landing sites ?

If I dropped a bullet and shot one from a gun that is held perfectly horizontal, will these bullets reach the ground at the same time? In other words: Will the horizontal force acting on the bullet fired make a difference on the time it takes to reach the ground?

ion leads to an increase in the amount of disorganization or disorder (disorder is the same thing as entropy)

My Biology book states that because when hydrogen ions (H+) are distributed randomly on either side of the membrane, no additional energy is needed to keep them that way, and the entropy, or disorder, of their arrangement has increased. The result is a more stable arrangement of H+ ions.

I need help understanding this concept. : (
