(Not sure which trial produced the most moles, so change the first sentence if needed) Discussion: Every trial produced a different amount of moles of gas, but the reaction that produced moles of gas nearest to the moles predicted by the Ideal Gas Law was Trial 1 of calcium carbonate. On average, calcium carbonate with hydrochloric acid formed the greatest amount of moles of gas, while Magnesium formed the smallest amount of moles of gas. Even though the Ideal Gas Law predicts that they should all form the same amount of moles of gas, the properties and attractive forces between each of the solids are different, so they actually all form different amounts of gas.

Unformatted text preview: Experimental error also could have contributed to varying results between the experimental and theoretical yields. To improve experimental technique, more than two trials could be performed. Also, the volume used in calculations was approximate, so measuring this value exactly would increase the reliability of this method to predict gas production. A more air-tight system, other than the flask and cork method, would also improve the reliability of this method, because the cork was easily tilted or crooked, which allowed for some pressure to escape and could have affected results....
