2. Abstract
We weight the educts and products while we did the experiment, that we can see how the chemical equation is balanced.
3. Introduction
We mixed Na(2)CO(3) and HCl together. The reaction began and the product CO(2) came out as a gas. The residue was NaCl + H(2)O.
4. Procedure
We put Na(2)CO(3) on the one side of the glass and the HCl(aq) on the other side. Then we took the funnel and stuck …

<Tab/>7) difference=(849ml-680ml):849=0.199x100= 19.9%
7.<Tab/>Conclusion
I learned how to balance a chemical equation in an experiment. I also saw that the measured and calculated mass by gases very different is, because we will lose all the time a lot gas.
