Calculate The Bond Energy Per Mole For Breaking All The Bonds Of Oxygen, O2?

799 O_O 142 O=O 498 H_O 464 Part A Calculate the bond energy per mole for breaking all the bonds in methane, CH4. Express your answer to four significant figures and include the appropriate units. Part B Calculate the bond energy per mole for breaking all the bonds of oxygen, O2? Express your answer to three significant figures and include the appropriate units. Part C Calculate the bond energy per mole for forming all the bonds of water molecules, H2O. Express your answer to three significant figures and include the appropriate units. Part D Calculate the bond energy per mole for forming all the bonds of carbon dioxide, CO2. Express your answer to four significant figures and include the appropriate units. Part E Calculate the approximate enthalpy change, _Hrxn, for the combustion of one mole of methane a shown in the balanced chemical equation: CH4+2O2_2H2O+CO2 Use the values you calculated in Parts A, B, C, and D, keeping in mind the stoichiometric coefficients. Express your answer to three significant figures and include the appropriate units.

Part A: _HCH4 = 1656 kJmol Part B: _HO2 = 498 kJmol Part C: _HH2O = -928 kJmol Part D: _HCO2 = -1598 kJmol Part E: _Hrxn = -802 kJ

About the flashcard:

This flashcard is meant to be used for studying, quizzing and learning new information. Many scouting web questions are common questions that are typically seen in the classroom, for homework or on quizzes and tests. Flashcards vary depending on the topic, questions and age group. The cards are meant to be seen as a digital flashcard as they appear double sided, or rather hide the answer giving you the opportunity to think about the question at hand and answer it in your head or on a sheet before revealing the correct answer to yourself or studying partner. Some questions will include multiple choice options to show you the options involved and other questions will just have the questions and corrects answers. Simply reveal the answer when you are ready to check your work. Absolutely no cheating is acceptable.
