3-4 pages lab report

attached you will find the result

here is the format

Purpose: Write one or two complete sentences that describe the objectives, or the reasons, for

completing the lab

Background Information: Present at least a paragraph of information that demonstrates your understanding of the chemistry concepts pertaining to this lab.

List of Materials: Include a list of materials needed to complete the experiment.

Procedure: If you are expected to design your own procedure, you must write the directions for the lab in a numbered list. Write them in a manner that other chemistry students would be able to follow them. If a numbered procedure is already provided, write a procedure summary in paragraph form.

Safety Considerations: List applicable safety rules to consider in this experiment. Include special handling and disposal instructions.

Data Table: Include tables with all the information that was recorded throughout the experiment. Tables should be easy to read and include appropriate headings and units.

Observations: Record the observations made during the lab.

Results: For repetitive problems, provide one sample calculation with appropriate units for each type of calculation. List the results of the calculations with units. In some cases, it may be convenient to record the results as another column on the data table. Percent error should be calculated in this section. For all calculations, the equation must be explained in words first before the numbers are used in an equation. Calculations may be hand written in ink.

Graphs: Data should be graphed with maximum use of the paper, labels on both axes with units, a title, and a best-fit line or curve through the data points. Not all activities will require a graph.
