Homework Help: Chemistry

Posted by Audra on Sunday, November 1, 2009 at 9:27pm.

I am trying to show that the combined weight of the reactants is equal to the combined weight of the reaction. When I placed CaCl2 into Na2 CO3 I didn't lose any weight. When I added Sulfuric Acid, I could not recork due to safety, therefore I lost Carbon Dioxide which reduced my weight. How can I safely contain the Carbon Dioxide to maintain the weight?
