The percent error between 20 and 20.5 is 2.5%
Explanation:
Percent Error = | (20.5 − 20) / 20 | × 100 = | (0.5) / 20 | × 100 = | 0.025 | × 100 = 2.5% (three decimal places)Percent Error = 2.5%
Answer:
pH will always be less than 7
Explanation:
This is because NH3 is a relatively weak base and the resulting Acidic salt on titration might hydrolyse to form a buffer solution
1. Since the track is extended outwards from lane one, the other lanes will be a longer distance then lane one. So the runners in the lanes (2,3,4,5,6,7,8) will start ahead of the runner in lane one so they all run the same distance. 2. The displacement of runner 1 would be that since they are farther back then they will have to run top speed in order to catch up to the other runners, especially runner 8 since it seems like they are so far ahead. This isn’t necessarily the same for all the runners because runner 1 is the farthest back and is at a disadvantage since they are in the inner lane and not the outer lane. I reallyyyy hope this helped :)
