Developing A Model Airbag

The reaction in exam 2 to the highest degree likely went to completion because there was an extreme increase in the add of CA gas produced and in our observations, we did not notice every reactants that had not undergone a chemical change. The more strong design of the model play a significant role in the large production of CA gas because Model 1 exceeded the mass limit, we used materials with smaller lot when we developed Model 2.Instead of the moldable weighing oat, we used the other plastic bags and also used less tape to attach It to the inside of our bag. In our previous trial, we noticed that acetic acid was leaking through the barrier. In effectuate to generate a more efficient separation mechanism, we placed the atomic number 11 bicarbonate in the scoopful instead of the acetic acid. The higher walls of the pocket used in Model 2 also served to prevent any of the sodium bicarbonate from falling out during transportation.However, like in Trial 1/Model 1, a possible source of error may be found in Our measurements it was difficult to accurately measure the raft of the acetic acid and to measure the height of our airbag aft(prenominal) the substances inside had reacted after the crash. In order to improve our experiment, it would be suitable if the trials were performed in a controlled environment at STOP to rule out any away atmospheric factors.If we had also employed more accurate methods of measurement, such as using a 5 ml graduated cylinder instead of a 10 ml graduated cylinder to measure the acetic acid, we may have been able to obtain a more correct reaction. The method used to measure the dimensions and spate of the bag was a minuscular unreliable because there was too great a chance of gracious error. A laboratory device, possibly electric, specifically designed to measure volume could have eliminated any discrepancies in our measurements and calculations.Model 2 would be the most hold design for inflating airbags. As noted in Table 1, not just did it produce the greatest amount of CA , even more than we had ab initio predicted, but it also met the mass requirements. It also included the most effective system of keeping the reactants separate but allowing them to quickly deploy when it was age to perform the trial. The high walls of the pocket were suitable for preventing the Enhance from pilling during the building or transfer of the model. The design was also lighter in mass and more compact in size.
