Question Description

Hi there,

write a formal lab report about Calorimetry-Measuring Heat of Formation Experiment following all the instructions below and from the lab manual attached. Please, make sure that the calculations are clear and accurate (watch sig figs)) and show work. Please write this experiment with zero plagiarism.

The formal lab report must have:

Title page, Objectives, Introduction, Procedure (leave it empty please), Safety, Waste treatment, Results, Calculations, discussion, and conclusion.

Lab Report: Calorimetry


The purpose of the Calorimetry experiment is to introduce you to application of thermochemistry. The purpose of writing the full lab report for Calorimetry experiment is to prepare you to write technical papers for journals, grants for funding, and learn to communicate scientific information to peers and the general public.


In this lab report, you will:

  • Analyze the data provided to you.
  • Compose a full formal lab report (title page, objective, introduction, procedure reference, results and calculations section, discussion, and conclusion).


This assignment will also help you to become familiar with the following important content information:

  • Calorimetry
  • Writing a complete lab report


This exercise asks you to collect, organize, analyze, and evaluate data you collected in the lab. You will type a lab report that includes the following:

  • Title page
  • Objective
  • Introduction
    • Give the logic of the experiment.
    • Be sure to define key terms and all applied experimental equations (e.g. calorimetry, calorimeter, enthalpy of formation, heat capacity of calorimeter, heat, balanced chemical equations, Hess’ law, and percent error.).
  • Procedure Reference
    • If there are any changes to the published procedure be sure to note them here.
  • Results and Calculations section
    • Table summarizing
      • Your major experimental data (e.g. heat capacity of calorimeter, experimental heat of formation for Mg2+ & MgO, actual heat of formation for Mg2+ & MgO, and percent error)
      • Be sure to include the PDF with the data that you were provided when you turn in your report.
  • One sample calculation of each type.
  • Discussion
    • We did not record the boiling and freezing point of water experimentally. But issues with these measurements could possibly be something that would cause error in this experiment. Perhaps something related to this would provide one of your sources of error?
    • State the heat of formation for MgO and describe any errors that may have led to an incorrect value of either the heat of formation (Mg2+ or MgO) or the calorimeter constant.
  • Conclusion
    • Reiterate the major experimental data.

    Here is the Data that you need to use for calculations and results:Part A 4.184
