Balancing Equations and a little math.
« on: October 11, 2009, 03:39:10 AM »
If you are given a 0.32 g piece of sodium metal to react with water, how many moles of HCl would it take to neutralize the sodium hydroxide produced?

I know that there are two equations you need to know and have balance
1. Na + H2O = NaOH + H
2. NaOH + HCl = NaCl + H2O

I just don't know what to do from there.

Any help is appreciated. Thanks!

First reaction is not correct - it should be H2 as a product.

How many moles of sodium used?

How many moles of NaOH produced?

How many moles of HCl required?

Do you know how to read reaction equation?
