Experimental Reactions Page (Stoichiometric Equation, Molar Ratio, Reaction
Mechanism)
This page, which is a Procedure (usually Procedure 3 or 4) is to be included in
any report dealing with a Synthesis Experiment.
It is to be placed on the page following the final computation of the Mole values
and just before the Limiting Reagent procedure.
To move the table to a different page, move the cursor over the table until a box
appears in the upper left (or right) hand corner. Right click on this box and select
Cut. Go to the page to hold the table and paste it into place.
Theoretical Yield (Mole Table) Summary Table
This table is to be placed on the page following the calculation of Theoretical
Yield. Note: Delete the explanatory text on the page as well as the table not
being used.
Adjusting size of cells in tables
Note: The entire template is a series of tables.
If a cell appears to have excess unused space, especially at the top or the bottom
of the table, do the following:
Place cursor in lowest point in cell and backspace through all unnecessary
line breaks to the point where your text ends.
Place the cursor on the bottom line of the cell (a double line will appear).
Move the cursor up until the desired cell size is attained.
Inserting Tabs within a Table Cell

Lab Report Structure
The Limiting Reagent
Whenever an experiment involves a "Synthesis" of a compound, a series of
calculations must be performed before you begin the experiment (in terms of the
report structure)
These calculations ultimately result in the determination of the "Theoretical
Yield." The steps, i.e., procedures, required to get to the theoretical yield are as
follows:
Determine the Mass of the first reagent
Determine the Mass of the second reagent
Note: If the determination of the two masses both involve the same technique,
e.g., weighing on a balance, then a single procedure can be used, otherwise two
procedures.
Compute the moles of both reagents.
On the reactions page, set up the Stoichiometric Balanced equation
and determine the Molar ratios between the reactants & products.
From the "Actual Moles" of reagents used and the Theoretical
Molar Ratio, determine the Limiting Reagent (show the calculations).
Using the Limiting Reagent and the Theoretical Molar Ratio
determine the Theoretical Yield in grams.
Mixing the Reagents and Initiating the Reaction
Once the Theoretical Yield has been determined for a Synthesis experiment,
the report can now focus on the actual experimental procedures.
The initial procedure usually involves obtaining and mixing the reagents.
Following the main reaction, it is usually necessary to perform one or more
procedures to separate the product from the reaction mixture, e.g., Vacuum
Filtration, Liquid / Liquid Extraction, etc.
After separation, additional procedures are used to clean up or purify the
product using Liquid/Liquid Extraction, Recrystallization, etc.

Identification of an Unknown Compound
For an experiment involving the identity of an Unknown compound, the
Theoretical Yield computations are not involved.
The unknown sample should be considered impure and therefore, the first
procedures in this type of experiment usually involve purification of the sample,
using such techniques as Simple Distillation for liquids or maybe
Recrystallization for a solid.
After purification, the sample is usually subject to a series of tests to provide data
for evaluating its identity and structure, such as Boiling Point, Solubility &
Density relative to water, Refractive Index, Melting Point, IR, NMR, etc.
Procedure Descriptions
In General, a procedure should be started on a New Page. Two or more
procedures can be placed on a single page if they can be accommodated in their
entirety, without crowding.
The left side of the page is used to describe the procedure, using complete
sentences in a Bullet format.
If the procedure involves a computation, describe and set up the equation being
sure to define the variables used.
Each procedure has a "Results" section on the "right side" of the page. This is
where you report your observations, the make actual calculations, or otherwise
state the results of the procedure.
Calculations for ALL results must be shown.
Note: The results are not analyzed in the Results section, just
reported.

Results Summary
Once all of the procedures are completed and you have accumulated the
experimental results, you then set up a new procedure to summarize the results
ALL RESULTS - using a "Paragraph" format.
Analysis & Conclusions
After you have summarized the results, the results are then analyzed in the
Analysis & Conclusions section with data supported arguments to support any
conclusions you have about the results.
NOTE:
Do not modify any of the table formats. If a cell is not applicable to your
report, leave the cell blank.
Specialized Procedure pages and analysis tables are available at the end of
this template. Copy of the applicable table to your to the appropriate place in
your report.
New pages can be added at any point in the report. Just click on Insert;
then Page Break
Obtain a copy of any specialized table from the end of this template and paste
it into the new page (deleting the old table if necessary)
