A double replacement reaction took place in step 4 between the copper nitrate and sodium hydroxide. Or, you can find the. University of Utah, UMich chemists improve batteries. Assessment Criteria for Written Lab Reports.
This lab is recommender for 1st year high school chemistry classes. San Fernando Senior High School. Students will need to create any data tables or spaces necessary for data collection in the lab. The length of heating was another source of error because the mixture may have needed to be heated less or more than the 5 minutes stated in the direction to get to complete the step.
References Include only those references that pertain to the question at hand. It never matters whether you need a lab report for your high school or college.
When the CuO was washed, the excess hydroxide ions that could have remained from the previous reaction were removed. Professor's Comments and Websites Introduction Writing in chemistry is similar to writing in other disciplines in that your paper must have a clear purpose that explains why you are writing, a thesis statement or main idea that defines the problem to be addressed, and background information wherever necessary.
After going back and analyzing the reactions in the lab, we concluded that he majority of the sources of error in the lab would cause a loss of copper and a decrease in the final mass.
Start by outlining, in point form, what you found, going slowly through each part of the figures.
They analyze high school records for academic rigor, taking a close look at. The reaction between copper and nitric acid is an exothermic reaction. A typical reference should look like Pavletich N. Another situation which was a source of error was during step 5 when the copper solution and water was heated so that the contents of the beaker would boil.
They should learn not only to identify sources of error but to evaluate how this impacts the final result. This short explanation should include the relationship between the variables that the graph is showing and its significance in relation to the chemistry concept that is demonstrated.
Lab reports are to be written for each experiment. Our company is specialized in delivering all types of academic writings but the most required one is lab report. Abstract in a lab report; it is often not required in introductory science courses.
Journals vary considerably in their preferred format for the reference list. For example, just because the data for graph N was collected before that of graph M does not mean that M shouldn't be presented first if it makes the presentation of data more coherent.
Six of the 16 labs conducted will be in a guided-inquiry format. Nuclear chemistry and gas behavior will be studied as well.
Carroll High Magnet School. There is an example of a well written lab report at the end of the rubric. Chemical formulas may be used, e.
If a table or figure is included in the report, it must be specifically referenced in the text as at the end of this sentence Table 1. The caption should be several sentences long and explain what the figure is, what result is found from the figure, and the importance of the result. This word-processed report is.
If there was any solid zinc that did not react with the copper sulfate and was left over with the copper precipitate, zinc particles may have significantly changed the mass of the final product.
When the final mass of copper was weighed, the balance may have not been calibrated correctly, and the copper in the evaporating dish may have contained impurities, such as un-reacted zinc, that changed the mass that was measured.
This section may be combined with the discussion section; that is, the last paragraph of the discussion section may act as a conclusion. In order to do this, they write up a lab report. Science teachers design lab experiments, understand the fundamental concepts and laws behind.
The abstract should be single spaced unless you receive other instructions from your professor. The percent yield of copper calculated was The following is the format for all investigations in this lab notebook, each section should be clearly labeled as stated below.
The purpose of the lab report is:reserves the right to have you re-write your lab report to correct obvious deficiencies prior to grading the report. Guidelines for Writing QUICK LAB AP Chemistry Laboratory Reports The guidelines for Quick Lab reports differ from.
