Lithium is metal and metals are generally in solid states.
Lithium reacts with water to give Lithium hydroxide along with hydrogen gas. In word equation, it is represented as;
Lithium + Water
In Chemical formula;
We can also write above equation by representing its state as below:
No, you would use the (s) state symbol.
LIthium is a solid at room temperature, so you would have to use the (s) state symbol for its reaction with water.
Lithium reacts with water in an exothermic reaction to produce lithium hydroxide,
LIthium hydroxide is a soluble salt, which means that it dissociates in aqueous solution to give lithium cations,
These two species exist in aqueous solution, so you would use the state symbol (aq) when writing the ionic equation
So, lithium is a solid, but the lithium cation exists in aquesous solution, that's why it requires the state symbol (aq).
