Developing A Model Airbag

The reaction in Trial 2 to the highest degree likely went to completion because in that respect was an extreme increase in the centre of CA gas haved and in our observations, we did non notice any reactants that had not undergone a chemical change. The to a greater extent effective designing of the model played a world-shaking role in the large achievement of CA gas because Model 1 exceeded the mass limit, we utilise materials with smaller mess when we developed Model 2.Instead of the plastic deliberateness oat, we used the other plastic bags and similarly used less tape to seclude It to the inside of our bag. In our previous trial, we spy that acetic acid was leaking through the barrier. In frame to generate a more(prenominal) efficient separation mechanism, we placed the atomic number 11 hydrogen carbonate in the pocket instead of the acetic acid. The higher walls of the pocket used in Model 2 in like manner served to pr eveningt 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 government notements it was herculean to accurately measure the saturation of the acetic acid and to measure the height of our airbag subsequently the substances inside had reacted after the crash. In order to improve our experiment, it would be suit commensurate if the trials were performed in a controlled environment at dampen to rule out any foreign atmospheric factors.If we had likewise employed more accurate methods of measurement, such as exploitation 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 blameless reaction. The method used to measure the dimensions and volume of the bag was a little unreliable because there was too great a chance of human error. A laboratory device, possibly electric, specifically designed to measure volume could have eliminated any discrep ancies in our measurements and calculations.Model 2 would be the most seize design for inflating airbags. As noted in Table 1, not only did it produce the greatest amount of CA , even more than we had initially predicted, but it also met the mass requirements. It also included the most effective system of keeping the reactants calve but allowing them to quickly deploy when it was clip to perform the trial. The high walls of the pocket were suitable for preventing the Enhance from pilling during the building or transference of the model. The design was also lighter in mass and more compact in size.
