What Is the Correct Molecular Formula for a Decomposing Nitrogen Hydride?

Click For Summary

Discussion Overview

The discussion revolves around determining the correct molecular formula for a nitrogen hydride that decomposes to produce gaseous elements, as well as identifying potential nitrogen oxides based on their reduction products. The scope includes homework-related questions involving chemical reactions and stoichiometry.

Discussion Character

  • Homework-related
  • Exploratory
  • Mathematical reasoning

Main Points Raised

  • One participant presents a homework problem involving the decomposition of a nitrogen hydride, suggesting possible candidates (NH3, N2H4, N2H6, N3H6) based on the stoichiometry of the reaction.
  • Another participant asks for clarification on what is meant by "possible equations" and requests a worked example to understand the problem better.
  • A third participant provides an example of a decomposition reaction equation, specifically for ammonia, indicating a potential approach to solving the first question.

Areas of Agreement / Disagreement

The discussion remains unresolved, with participants exploring different aspects of the problems without reaching a consensus on the correct answers or methodologies.

Contextual Notes

Participants have not yet established any assumptions or definitions that could clarify the problems, and there are unresolved steps in the mathematical reasoning required to solve the questions.

What do you mean by possible equations? Can you solve 1 question for me so i can have 1 example to refer? ><
 
Reaction equations of decomposition reactions. For example:

2NH3 -> N2 + 3H2
