    I know how to balanced equation. But I don't know which is (aq), (s), (l), and (g). 2 KCl + Na2CO3 = K2CO3 + 2 NaCl

    @UnbelievableDreams you mean what the symbols (aq) mean or which compound is in the solid etc ?

    Do you have a solubility table/rules?

    No. @JoannaBlackwelder Which compound? @Photon336

    @JoannaBlackwelder I know that this is a double displacement reaction, wouldn't it be KCl(s) Na2CO3(aq) = K2CO3(aq) + NaCl(aq). assuming this is done in water...

    @UnbelievableDreams you're asking what the phases each of the reactants and products are in the equation right? did they give any more info about the reaction?

    @Photon336 Yes, I wanted to know reactants and products. Like how do you know KCl is a solid?

    KClis ionic, and it's a solid, ionic compound are solids at room temperature

    Do it have rules? Because I have few equations that I need to know if it is solid.. etc

    there are solubility rules but but those depend on what solvent you're dissolving it in. I believe both KCl(aq) Na2CO3(aq) are soluble in water = as well as K2CO3(aq) + NaCl(aq)

    sorry when i meant it i mean like any particular compound you're looking at

    I think it's this K2CO3(aq) + 2 NaCl(aq) = 2 KCl(aq) + Na2CO3(g)

    any compound could be solid, liquid, gas, or aqueous, depending on the situation. Because this is a double displacement, I'd be willing to bet that all 4 are (aq)

    @Photon336 you've got \(Na_2CO_3\) as a gas up there, you're going to want to fix that

    Honestly, I am confused. I wanted to know how you get this. I have another equation. Na2SO4 + BaCl2 = BaSO4 + 2NaCl Which compound is in solid, etc.. :/

    for this one you need to know the solubility rules

    the \(general\) patterns that ionic compounds will either dissolve in water (aq) or precipitate (s)

    all the \(reactants\) in a double displacement reaction like this will be (aq)

    It makes sense, thank you.
