Answer:
1. Absorbs electromagnetic energy
2. Energy difference between the two orbits.
Explanation:
Bohr precisely describe the processes of absorption and emission of energy in terms of electronic structure. According to Bohr's model, an electron would absorb energy in the form of photons to get excited to a higher energy level as long as the photon's energy was equal to the energy difference between the initial and final energy levels. After jumping to the higher energy level or the excited state, the excited electron would be in a less stable position, so it would quickly emit a photon to relax back to a lower, more stable energy level.

Answer:
С3Н6.
Explanation:
Hello!
In this case, since addition reactions imply that a radical or some radicals are added to the parent chain, we notice that only unsaturated hydrocarbons are able to undergo addition whereas saturated ones undergo substitution reactions as they already have all the carbon bonds bonded to leaving groups.
In such a way, we can rule out C2H6, C3H8 and CH4 as they are all alkanes; therefore, only С3Н6 is able to undergo an addition reaction due to the C=C which is able to lose one of those bonds and allow an incoming radical to get included into the parent chain.

Explanation:
A process where two or more number of miscible liquids present in different fractions are separated by boiling at different temperatures is called fractional distillation.
The sudden decrease in temperature is because the compounds having lower boiling point have completed the distillation before vapor of the higher boiling point can actually fill the distillation head.
Answer:
This question lacks options, the options are:
A. Moral and ethical beliefs
B. Popular support
C. Compelling evidence
D. Historical support
The answer is C. Compelling evidence
Explanation:
Scientific investigations are used to proffer solutions to problems or answer a question. However, before these scientific ideas can be accepted or rejected, it must be subject to falsifiable testing via experiment.
A hypothetical statement is given to explain a scientific observation, which is subjected to further testing via experimentation. The outcome of the experiment provides a COMPELLING EVIDENCE on which the acceptance or rejection of a scientific idea is based.
