Lengths. Practice Exercise 1
Hypothetical elements X and Y form a molecule XYz, in
which both Y atoms are bonded to atom X (and not to one
another). The X-X distance in the elemental form of X is
2.04 Å, and the Y-Y distance in elemental Y is 1.68 Å. What
would you predict for the X-Y distance in the XY2 molecule?
(a) 0.84 Å (b) 1.02 Å (c) 1.86 Å (d) 2.70 Å (e) 3.72 Å

What forms when chemical reactions combine pollution with sunlight?

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
