look on the periodic table, there are sections of element in groups, for example and some u just have to memorize. Hg is always a liquid at room temp but turns solid when exposed to a slightest change in temp. know some basic facts: the nobel gas section of the periodic table are all gases, the transition elements are almost all solids and compounds, it all depends on the solubility rules to determine is they are solid or aquaeous, i think no compounds are gases only elements can be besides the diatomic elements sich as HOF BrINCl: hydrogen2, OXygen 2, Flourine 2, Bromine 2 .. etc when they r alone in a chem equation, i hope this helps, remember know ur solibility rules for solids and aquaeous solutions and the rest look on the periodic table to help with gases. :)

Any chemical equation will be silent about the physical state of the matter. Unless you read the text, you won't be able to make out whether one is solid, liquid or gas.

You have to find a solubility chart, and also study the rules for solubility. My students have the rules in their text and a solubility chart in the appendix of their lab book.

You have to understand the nature of the reactants and products.

Actually, you cannot determine. It should be stated in the question. Otherwise, you can't.
