MACT Reaction of Sodium Carbonate with Hydrochloric Acid Lab Report
In the lab, sodium carbonate reacts with hydrochloric acid to produce sodium chloride, water and carbon dioxide.1) Write out the formulas and balance the equation
2) What was the mass of the empty crucible and cover?
3) What was the mass of sodium carbonate used to start the experiment?
4) Using the balanced equation and the starting amount of the sodium carbonate used, calculate the expected (Theoretical) yield of sodium chloride. In other words, do a stoichiometry problem using the starting amount of sodium carbonate (recorded in question 3) to see how much sodium chloride is produced.
5) What was the mass of the crucible and cover and sodium chloride?
6) What was the actual mass of NaCl produced?
7) How does your calculation and the actual amount of NaCl produced, compare? To see, let's calculate the percent yield by using this formula:Take the actual amount of sodium chloride (answer from #6), divide it by the amount you calculated that you should get ( answer from #4) and multiply by 100.What was your percent yield?
8) Indicate any source of error in the experiment and how it could be corrected.

GC Physiology Urinalysis Graphs and Summary Paper
Part I: Create four separate graphs based on the data obtained from Canvas: Specific Gravity vs. Time (line graph: use data for all groups)Urine Volume vs. Time (cumulative line graph: use data for all groups) Note: you will have to add the urine volumes together to obtain the cumulative volume (e.g. the cumulative volume at 60 minutes would be the sum of the individual volumes at 20 minutes + 40 minutes + 60 minutes)Urine Production Rate vs. Time (line graph: use data for all groups)% return (bar graph: only 500 ml and 1000 ml water loading groups)On each graph include the data supplied by the other groups. (See Canvas)Add a title to each graphLabel each group with a distinct symbolProvide a legend for your graphMake sure you label your axes with the correct units (i.e. “Time (minutes)”, “Urine volume (ml)” and “Urine Production Rate (ml/minute).” (Note: Specific gravity has no units) Part II: Graph summary paragraphs for each of the four graphs. 1. In a separate section under the heading Summary, write a separate one paragraph summary for each of the graphs. Part III: Submit the four graphs and summary paragraphs as a single document (PDF, Google doc, or Word file) using the submission link in this module.
