Question

This symbol <– –> indicates:




A. an incomplete combustion reaction.


B. that heat must be applied.


C. that a gas is formed by the reaction.


D. that the reaction is reversible.

Answer 1

That symbol, <--> indicates resonance, it is another valid structural representation of a molecule (although usually one is more valid than the other but that depends, that is not the case for some aromatic molecules)


If this is the symbol you mean, it means equilibrium, which just means that the reactants and products exist in a certain detectable proportion


this means that all reactants have been used to form products

Answer 2

an equilibrium reaction can also be denoted as reversible

Answer 3

note my explanation of the resonance arrow is kind of a quick breeze through dont hold it to be absolutely accurate

Answer 4

<--> also means reversible
in theory all chemical reactions can be reversed

Answer 5

<---> is strictly for resonance nincompoop, people use it as a short cut on the internet because people are too lazy to look up ⇌

Answer 6

I guess it doest accept text equilibrium arrows
