why might one expect the water vapor spectrum to be different than the hydrogen lab spectrum?

Expert Solution

The lines in the spectrum of H₂O is entirely different than that of each diatomic atoms of hydrogen and oxygen.

The main reason for this is the differences between the exited state orbitals and the groundstates of molecular orbitals which overlaps with the sp3 hybridized orbitals of oxygen.

As steam is opaque to light it appears white because it is composed of small minute droplets of liquid water and hence it appears white. steam is not considered as WATER VAPOR, it is only the gaseous form of water. contrary to steam water vapor is transparent hence the spectral lines will not change. It also does not change with temperature

1 a) Water can decompose to hydrogen and water vapor at high temperatures. You're pondering a little this and suggests the following mechanism: ?2? → ?? + ? Ka ? + ? → ?2 Kb ?? + ?? → ?2?2 Kc ?2?2 → ?2 + ?2 Kd From this information, derive an expression of the hydrogen formation rate. Don't forget to clearly state any assumptions you make. b) Suggest what information could be used to either support the mechanism or...

Why are vectors essential for doing physics? There might be more than one correct answer. a.Vectors are not needed for idealized particles with zero volume, but they are needed whenever an object has volume. Since all real objects have volume, vectors are needed. b.Even though vectors are purely mathematical constructions (i.e. you will never see a vector in the real world), they add together in exactly the same way that real world phenomena add together. c.The universe has more than...
