Furthermore, pay attention to the units of your results!Also do not to forget to write the axis names in the graphs you will plot!Calculate the errors of your results!QUESTIONSIn text references are like the below ones1)Hess’s Law:Enthalpy and internal energy are state functions and overall enthalpy change is independent of the path of the process .The overall reaction’s enthalpy is equal to sum of the individual reactions’ enthalpies.This law is called Hess’s Law.(1)In Hess’s Law,….. are the same.(2)2) Heat capacity:amount of heat which is required for the increasing the temperature of a system by 1°C(3) Specific heat:heat that is required to increase the temperature of 1 g of matter by 1 °C …..DISCUSSION (an example for our IR experiment)We used gas phase because ….We could have used gas phase But we could not use aqueous phase since ….We found the bond length of HCl to be which was theoretically. Our result is very close to the real value with an error less than 1% therefore we can say that our experiment is quite successful. Actually, we should be observing a broad peak at .…cm-1 but there was no peak. This region is called Q branch since….; The peaks are almost equally spaced because …. But we could not observe this since …Also in our spectrum there are some peaks that can be seen as doublets. These are the result of …. …Discuss your results in detail and compare them to theoretical ones. Also mention and discuss the sources of errors occured during your experiments, how did they affected your results, and how to eliminate those errors.
