If all i have is the chemical formula for an compound or element, or even an equation, what is it's state

Question

without the annotations for solid liquid or aqueous in subscript. if this has to just come by memory, then please provide a link. no annoying answes like: states change blablabla. thank you

Answer 1

[Answer:

A lot of compounds you'll eventually get around to memorizing after a while.

Here is a list of compounds that have a low solubility in water, that is, they form a solid precipitate in water:

In general however, many compounds will be aqueous.

You should be able to recognize metals (e.g.: Na, Zn, etc.) and know right away that they should be solids. Ions are aqueous and gases are gases (e.g.: O2, CO2, O3, etc.). However, many compounds, such as water (H2O), can have many states (solid, liquid, gas are all possible) and thus depend on the reaction.]
