An egg is fried in a skillet, a chemical or physical properties?

Click For Summary

Discussion Overview

The discussion revolves around the classification of various processes and substances as chemical or physical properties, specifically focusing on frying an egg, burning natural gas, and the dissolution of iron in acid. Additionally, there is a query regarding the purity of a compound based on mass analysis of samples.

Discussion Character

  • Conceptual clarification
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant questions whether frying an egg is a chemical or physical property, indicating uncertainty about the classification.
  • Another participant suggests that all chemistry is physics, implying that physical properties might always be the correct classification.
  • There is a repeated inquiry about the classification of natural gas burning with a yellow flame, paralleling the egg frying question.
  • A participant proposes that to determine if a compound is pure, one should analyze the relative mole values and empirical formulas of the samples, suggesting that distinct formulas indicate a crude substance.
  • Another participant counters that comparing percentage composition alone may suffice for determining the purity of the compound.

Areas of Agreement / Disagreement

Participants express differing views on whether frying an egg is a chemical or physical process, and there is no consensus on the best method to determine the purity of the compound from the sample analysis.

Contextual Notes

Participants have not reached a resolution on the classification of the processes discussed, and there are assumptions regarding the definitions of chemical and physical properties that remain unexamined.

Please help urgent

Please help, I have few questions

1.Natural gas burns with a yellow flame, a chemical or physical properties?

2.An egg is fried in a skillet, a chemical or physical properties?

3. When iron is dissovled into a acid. Has the iron atoms destroyed? Give answers with why?

4.A particular compound is thought to be a pure compound. Analysis of three
samples of the material yield the following results.
Mass of sample Mass of carbon Mass of hydrogen
Sample 1 1.000 g 0.937 g 0.0629 g
Sample 2 0.244 g 0.229 g 0.0153 g
Sample 3 0.100 g 0.094 g 0.0063 g
Could the material be a pure compound?
I really don't understand this question

Welcome to PF, someone21.

All chemics is physics. So physical is arguably always the right answer.
For the rest, please https://www.physicsforums.com/showthread.php?t=94384 first, especially point 1 and 2.
 


Asking someone to follow forum rules doesn't work, I have tried that at chemicalforums last Wednesday.

Find the relative mole values and the empirical formula , if the three samples have distinct empirical formulas than you have a crude substance if they are the same then the probability is that you have one compound.

No need for that, just comparing percentage composition will be enough.
