Is it correct to use the symbols (l) and (g) in every reaction?

I know that this question might sound stupid to most of the people, but for a chemist noob like me is not very clear. So, here's the main question: 


**Is it appropriate to use the symbols (l) for liquids and (g) for gas in any reactions, or do the reactions have to be specific for a certain application?** 


The reason why I'm asking this is that in most of the cases, you don't see this notation. Also, are there other notations, for example (v) for vapor, or (s) for solid??
