Bohr Model: an electron in a doubly ionized lithium atom +2Li(three protons in the nucleus) makes a transition from the 풏=ퟏto the 풏=ퟑlevel with an associated photon. a)Determine the photon energy associated with this transition. (10pts)

2. how is heavy water different from normal water

Which scenario is most similar to the type of collision that gas particles have according to kinetic molecular theory

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
