When running a spectrum of a neat liquid, what are problems that may arise when: a. using a low-viscosity liquid? b. using a viscous liquid?

Answer 1) : Weak peaks

Explanation : When running a spectrum of a neat liquid, the problems that may arise using a low-viscosity liquid there will be weak peaks obtained and it will be difficult to interpret them. As there will be very thin path length between the salt plates to obtain the spectrum. The quality of the peaks will be low.

Answer 2) : Strong peaks

Explanation : When running a spectrum of a neat liquid, while using a viscous liquid the obtained peaks will be strong peaks. As the viscous liquid will enable to form a thick layer between the salt plates which will produce strong, intense and sharp peaks. This will be high resolved and clear peaks on the spectrum.

b

explanation:

mitosis

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
