A 0.100 mol sample of propane, a gas used in many homes in these days of load shedding, was placed in a bomb calorimeter with excess oxygen and ignited. The reaction was C3H8 (g) + 5O2 (g) → 3CO2 (g) + 4H2O (l) The initial temperature was 25.000 0C and its total heat capacity was 97.1 kJ 0C –1 . The reaction raised the temperature of the calorimeter to 27.282 0C? A. How many joules were liberated by the combustion of the propane? B. What is the ΔE for the reaction expressed in kJ mol–1 C3H8? C. Calculate ΔH for the reaction in kJ mol–1 C3H8

Is there a diagram/picture you can provide? it seems this question goes along with a

C. definite shape, definite volume. that is a solid.

What's the answer to this question is how do you know

In order to improve results, many different steps can be taken into account. 1) using more precise scales and thermometers is always something that should be considered as being precise means that you are more exact with your answer.2) increasing the sample size should also be considered, if you have a bigger sample size you are able to determine if your results are accurate as well as if there are any variables that should be taken into account plus it assists in the statistical analysis and produces overall better data3) using better handwriting is also a plus, along with organizing the data properly so that others are also able to read the results and even redo the experiment in the future if it is needed.
