Use a balanced chemical equation to represent a chemical reaction.Water (H2O) is composed of hydrogen and oxygen. Suppose we imagine a process in which we take some elemental hydrogen (H2) and elemental oxygen (O2) and let them react to make water. The statement:hydrogen...

So sometimes when something is listed as aq you do put a separate water molecule in the equation and sometimes you don't. Maybe at this point we should just take our best guess because we don't have enough knowledge to do anything else?One thing I think I am noticing as I teach throu...
