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

2. Abstract We weight the educts and crops while we did the experiment, that we sens see how the chemical substance comparing 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 muck up. The remnant was NaCl + H(2)O. 4. Procedure We rear Na(2)CO(3) on the ane perspective of the film over and the HCl(aq) on the other side. Then we took the funnel and stuck it in a preventive and put both in the glass that no mess up comes out. Then we took the piston sleeping room and filled it up with awry(p) and put it upside downward in a beaker overweight of irrigate. There should be no burn out in the piston chamber! Now we shaked the glass with the ii substances and the reaction began. There came bubbles (CO(2)) gas which went into the cylinder. Then we calculated the pile of gas in the cylinder. The piddle was sided out after one day in the baker and we could also calculate how oftentimes water and NaCl in the eternal rest was left. 5. Look on the stem 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/mole          jettyar circumstances of NaCl: 58.443g/mole         Mole Na(2)CO(3), 4.02g:105.988g/mole=0.0379mole          destiny of NaCl: 0.0379x58.443g/mole=2.215gx2= 4.43g                  3) Entire nap: 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 garner how to balance a chemical equation in an experiment. I also saw that the measurable and calculated mass by gases very different is, because we leave behind lose all the powder store holder a portion gas.
