We will always be interested in the change in H, rather than the absolute value of H itself. When a chemical reaction occurs, there is a characteristic change in enthalpy. The enthalpy change for a reaction is typically written after a balanced chemical equation and on the same line. For example, when two moles of hydrogen react with one mole of oxygen to make two moles of water, the characteristic enthalpy change is kJ.
Hire Writer The report must be typewritten or use a word processor and should not be written in the first person. A page number should appear either in the upper right hand corner or the bottom center of each page except the first page of the report.
The report should contain each of the following: Purpose of the Experiment: This should be a brief statement explaining why the experiment was conducted. Abstract Be sure to include names of lab partners and unknown numbers. Or you will lose points.
A very brief outline of the procedure s you used along with a list of any special equipment should be given here. Drawing of Equipment this is rarely used: A labeled drawing of any specialized equipment setups should be presented here.
If you do a drawing, it should look GOOD. A digital photograph is an acceptable substitute. Cameras are available in the stockroom. Table of Data and Results: Data and results should be presented in a neat tabular form must be typed.
All Tables should be labeled. All the data should have units. Any formulas used should be presented here. You may accomplish this using an ink pen. Graphs should be neat and utilize as much as possible of the whole page without compromising the scaling.
Graph title should be an accurate description of what is being plotted. For experiments that use the slope, the slope should be printed on the graph. Any questions asked in the lab should be answered here in complete sentences.
In this section, the experiment and the results obtained are discussed that results in a conclusion of what was learned. The conclusion should directly address the purpose of the experiment.
Also any problems encountered in the experimentation are stated along with any suggestions for improvement of the experiment. Sign and Date your report.
