A class of students all performed the standardization of the same solution of sodium hydroxide using the procedure outlined in the experiment “Titration Curves” that normally runs during the semester. Using the data provided in the Excel spreadsheet (available under FILES in Canvas) under Tab 1 – Standardization) make a determination as to the concentration of the solution. Be careful to report the appropriate number of significant figures.

You can either upload a picture of your work, or a spreadsheet of your work. Either way, make sure that it is clear why you are excluding any data that you decided to exclude, and that you show your work, and clearly indicate what you are reporting the concentration of that solution to be.

Explain what happens at the saturation point when adding salt to water at room temperature.

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet

Asuspension of yeast cells is being grown under anaerobic conditions such that glucose is degraded to ethanol and carbon dioxide. if one wishes to follow this process by monitoring the release of 14co2, at which positions in the glucose molecule would the 14c label need to be incorporated?
