SUMMARY

This discussion focuses on understanding bond enthalpies, specifically the processes of making and breaking bonds during chemical reactions. The user seeks assistance with parts "b" and "c" of a problem related to bond enthalpy calculations. A suggested method for resolving the issue involves listing all bonds present before and after the reaction to clarify which bonds are formed and which are broken.

PREREQUISITES
  • Basic understanding of chemical reactions and bond formation
  • Familiarity with bond enthalpy concepts
  • Knowledge of how to interpret chemical equations
  • Ability to analyze molecular structures
NEXT STEPS
  • Study bond enthalpy tables for common molecules
  • Learn how to calculate total bond enthalpy changes in reactions
  • Explore the concept of Hess's Law for enthalpy calculations
  • Practice with chemical reaction diagrams to identify bonds
USEFUL FOR

Chemistry students, educators, and anyone interested in thermodynamics and chemical reaction mechanics will benefit from this discussion.

Bond Enthalpies..please help!

Got the first one, but can't figure out how to do "b" and "c." Not understand which ones make/break.

If you don't see it, try brute force approach - list all bonds before reaction and after reaction.
