3. When written in a chemical equation, the symbols (s), (g), (letter L) and (aq), indicate whether the reaction will proceed quickly or more slowly. True False
That would be FALSE. What those letters as subscript actually tells is the state of the different species i.e. (s) means solid, (g) means gas, (L) means liquid and (aq) stands for aqueous.
The equation that follows is an example of the state symbols in use: [tex]2Na_{(s)} + 2H_{2}O_{(l)} [/tex] → [tex]2NaOH_{(aq)} + H_{2} _{(g)}[/tex]
