i REALLY dont get it.
we're doing it in class right now, but the professor isnt doing a very good job of explaining it, and the whole class is stumped.
for example, how would you balance this equation?
CaCl^2 + NaHCO^3 --> NaCl + Ca(OH)^2 + H2CO3
can someone please explain how to do this in general?
thanks in advance.
