Chapter 3.1 Problem 3.1
Question
Classify each of the following pure substances as an element or a compound:
a. a silicon \((\mathrm{Si})\) chip
b. hydrogen peroxide \(\left(\mathrm{H}_{2} \mathrm{O}_{2}\right)\)
c. oxygen gas \(\left(\mathrm{O}_{2}\right)\)
d. rust \(\left(\mathrm{Fe}_{2} \mathrm{O}_{3}\right)\)
e. methane \(\left(\mathrm{CH}_{4}\right)\) in natural gas
Solution
The first step in solving 3.1 problem number trying to solve the problem we have to refer to the textbook question: Classify each of the following pure substances as an element or a compound: a. a silicon \((\mathrm{Si})\) chip b. hydrogen peroxide \(\left(\mathrm{H}_{2} \mathrm{O}_{2}\right)\)c. oxygen gas \(\left(\mathrm{O}_{2}\right)\) d. rust \(\left(\mathrm{Fe}_{2} \mathrm{O}_{3}\right)\)e. methane \(\left(\mathrm{CH}_{4}\right)\) in natural gas
From the textbook chapter Classification of Matter you will find a few key concepts needed to solve this.
