OBJECTIVE, GRAPH and TABLE RESULT

Objective – To investigate the relationship between the molality and the boiling point of a solution. 1.     In each of the 6 test tubes, measure 5.0 g acetone. 2.     Leaving one of the test tubes, add 0.4, 0.8, 1.2, 1.6 and 2.0 g of benzioic...

HYPOTHESIS

·        Hypothesis: We think that when more molality is given, the boiling temperature will increase, because of the relationship between moles and kilogram. When we have more moles, we would have more kilograms and this will take longer to boil, so if it takes...

CONCLUSION

·         Conclusion: We can see that after the realization of the experiment, our hypothesis was true and happened what we predicted, because we can see how the boiling point increases when the molality increased. In our result table, we can also see in the...

EVALUATION

·         Evaluation In summary, we really find out the experiment very easy with a very easy method, however, there were, like in all experiment, some aspects more difficult than others but the one that we think is the most important is: The way of measuring...

HYPOTHESIS

HYPOTHESIS: What we expected, when we did experiment, to find, was what actually happened. We thought that when we have more molecular mass, in other words, when we have a bigger molecule (having more Carbon, Hydrogen and Oxygen), they are going to have stronger Van der  Vaal´s forces and this...

VARIABLES

The independent variable is the variable that we change in the experiment, so in this experiment what we are going to change is the substances used to the see their properties (to see their different surface tension). Dependent variable will be the volume of surface tension, because is the variable...

CONCLUSION & EVALUATION OF THE METHOD

EVALUATION OF THE METHOD: We think that the method contain three key parts that every method should have: Clear instructions, nice statements and easy comprehension; so it was easy understood. So we do not really think that the method needs any correction, except some things such as how it suppose...

INTERMOLECULAR FORCES

INTERMOLECULAR FORCES : Butyl acetate: permanent dipole-dipole Methyl acetate : permanent dipole-dipole Ethyl acetate : permanent dipole-dipole Propyl acetate: permanent dipole-dipole All of them also have Van der Vaal´s forces

OBSERVATIONS

OBSERVATION OF MY RESULTS: Before reading all the information that I rode out, I have normal results except the results given with ethyl acetate, and from the results, knowledge and data from the internet, I lead to different possible ideas that could happen: The first idea is that maybe Ethyl...
