Answer:
An endothermic reaction
Explanation:
A positive sign indicates that energy is absorbed. Hence it is an endothermic reaction.
A reversible reaction is indicated by a double arrow on the chemical equation.
A spontaneous is indicated by negative Gibbs Free Energy (G) value.
An exothermic reaction is indicated by a negative enthalpy change
Methane, CH4, would have the lowest boiling point among the three since it has the lowest number of carbon and has no functional groups. Methanol would have the highest boiling point since it has a functional group which contains hydrogen bonding which much stronger than the one in CH3Cl. Hope this helps.<span />

sorry to do this but I really needed some points to ask my question from someone else so that's why I am doing so really sorry and thank you for free points
Answer:
The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule making a transition from a high energy state to a lower energy state. ...
Explanation:
Therefore, spectroscopy can be used to identify elements in matter of unknown composition.
