SB Spoiler: Need help with SB C/P #8

[salemstein]

I seem to falter at tackling these vague Q stems. What is an "appropriate" laser, and how the heck do you assume that with an "appropriate" laser, all of the laser energy gets transferred into breaking chemical bonds (which presumably makes detected energy levels coming out = 0?)

Bump. need help with this
i read this as energy = ΔHu = (Em- ΔHnr) so i picked B.

An "appropriate laser" will not have any excess in energy after breaking a bond. According to the passage, the laser was designed to be LARGER than the energy needed to break a bond.

So this means the excess energy is absorbed by the solution and turned into heat therefore the meter picks it up as zero? Is that what aamc, means by energy conservation in their explanation
