1. Which analytical balance is the more accurate? Why?
2. Which piece of glassware is best at measuring the density of water?
3. What two aspects of the data set you cited in Question 1 define it as “best”?
4. What does “standard deviation” measure?
5. (a) Calculate the standard deviation of the data set you labeled as having the least random error in the first experiment with pure water.
(b) Calculate the standard deviation of the data set you labeled as having the MOST random error in the first experiment with pure water.
(c) What does the standard deviation tell you about these two data sets? Does that agree with your labels for “least” and “most” random error?
6. (a) Did your measurements exhibit random error? Briefly explain. (Hint: Remember

Alka Seltzer Lab Report

A possible error that could have been made was not doing at least three experiments. If more experiments were done, the information would have been more accurate. Another possible error was only using two liquids. If more than two liquids were used in this experiment, then the information would have also been more accurate. A major error in this experiment was using a different starting temperature for each trial.…

Antiseptic Lab Report

Two ways this experiments data could be considered more reliable is that, there were many runs of the experiment done all with the same parameters and the results are an average of all of the groups’ data. Another reason would that each group could have done the experiment slightly differently and gotten a different result thus showing what changing a variable can do to change the results. One region of bias in this experiment would be that one of the antiseptics used was the Purell hand sanitizer, which is intended to be used on ones hands instead of the face, so it would work less effectively than intended. Two experimental errors our group could have made would be: The agar could have been broken thus preventing bacteria from growing in the gash made. Or our group could have transferred more bacteria to one of the quadrants and not equaled the amount of bacteria in the other quadrants of the Petri…

Changing The Surface Of A Penny Essay

The answer is that by changing the surface of the penny, the penny holds less drops of water because the soap is filling up the cracks, and the surface. 2. Write your hypothesis from part B. If we change the surface of the penny by putting soap on the penny then, the penny will hold less drops of water, and we will get different results then the original. 3. List at least 3 pieces of data from your experiment(and your textbook/notes) that shows support for or refutes your hypothesis.…

Soapy Water Experiment Results

The trials were used to show how soap can change the droplets that could be held on the penny. The results of the trial helped me see what happened when I added soap to the water. It tells me whether my hypothesis was correct when I tested it and whether the results can prove my point. After analyzing the data, my hypothesis was correct. I was able to see a trend that the penny was able to hold 40+ droplets of tap water each time, but there were some exceptions, while the penny was able to hold 10+ drops each time.…

Dissolved Impurities Lab Report

The purpose of this lab is to understand the effect that dissolved impurities will have on the freezing point of a mixture and what additive will affect the the freezing point the most. The freezing point of a liquid is, the point of a substance when the temperature of the solid and the liquid is equal. When water freezes the water molecules become organized and come closer together forming crystal particles of ice. When a solute (like salt) and a solvent (like water) mix together the salt becomes an impurity and makes it so the solution can’t crystallize.…
