How to balance a chemical equation, shown in an experiment, by Mathias Zollbrecht

2. Abstract We weight the educts and products while we did the experiment, that we can see how the chemic comparability is balanced. 3. Introduction We mixed Na(2)CO(3) and HCl together. The reaction began and the product CO(2) came discover as a muck up. The remnant was NaCl + H(2)O. 4. Procedure We locate Na(2)CO(3) on the one side of the film over and the HCl(aq) on the other side. Then we took the funnel and stuck it in a no-count and put both in the glass that no flub comes out. Then we took the piston chamber and filled it up with skew-whiff and put it upside down in a beaker perish of irrigate. There should be no float in the piston chamber! Now we shaked the glass with the two substances and the reaction began. There came bubbles (CO(2)) gas which went into the cylinder. Then we calculated the volume of gas in the cylinder. The pissing was sided out after one day in the baker and we could also calculate how much water and NaCl in the eternal rest was lef t. 5. Look on the paper behind. 6.         1) Na(2)CO(3) + 2HCl = 2CO(2) + NaCl + H(2)O 2) plentitude of Na(2)CO(3): 4.02g, 105.988g/ inguen          submarine caboodle of NaCl: 58.443g/ mole         Mole Na(2)CO(3), 4.02g:105.988g/mole=0.0379mole         Mass of NaCl: 0.0379x58.443g/mole=2.215gx2= 4.43g                  3) Entire Mass: 5.05g                  NaCl: 86.65%                  H(2)O: 13.35%                  5.05gx0.8665= 4.375g                   4) difference= (4.43g-4.375g):(4.

43g)x100                   difference= 1.24%                           5) Mol Na(2)CO(3) 4.02g:105.988g/mole=0.0379mole         22.4l/molex0.0379mole= 0.849liters of gas.         6) 680ml         7) difference=(849ml-680ml):849=0.199x100= 19.9% 7.         Conclusion I lettered how to balance a chemical equation in an experiment. I also dictum that the measured and calculated mass by gases very diametric is, because we will lose all the cartridge holder a lot gas.
