The size of the canopy does not affect how quickly the parachute falls to the ground. The results showed that the small canopy (5cm x 5cm) fell to the ground the quickest and the larger canopy (20cm x 20cm) took the longest to fall to the ground. The results of my experiment fail to support my hypothesis. I have learned that the reason the smaller canopy was able to fall quick is because it has a smaller surface area which means that there is less air resistance pushing up on the canopy and slowing it down as it falls to the ground.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
