Okay, I've always been having trouble creating chemical equations. Can someone please help me! For example, I need to write a balanced equation for the dissolution of sodium carbonate in water. I know the reactants would be Na[2]CO[3] and H[2]O, but I do not know how to predict the products!

It is a double replacement reaction.
You will get NaOH and H2CO3. However, the carbonic acid decomposes to yield water and CO2 gas.

I love the wording here, predict the products, it makes me smile, because it reminds me of my physical chemistry professory, Dr. Christopher Burba. First of all it is not magic, but the way to look at it would be replace what is on one side of the periodic table something that is on the similar side. This would be a double replacement reaction. So it seems that is would be a final product of carbonic acid. and Na2O

i think the equation is
Na[2]CO[3] + 2H[2]O --> 2NaOH + H[2]CO[3]
if having trouble i tend to first write an ionic equation and then match opposite charges in a different way than seen in the reactants
