Question
Chapter 2, Problem 4STP
Interpretation Introduction
Interpretation: Number of pure compounds in substance, sodium, sugar, air, iron needs to be determined.
Concept Introduction: Practically all of the matter in environment consists of mixtures of different substance. For example, soil; it has many forms of components, air; it has mixture of many gases, etc.
Expert Solution & Answer
Answer to Problem 4STP
Correct answer: Option C.
Explanation of Solution
Reason for correct option:
Substance is made up of the similar types of the atoms. A sample of matter with both definite & constant composition and also distinct chemical properties called a pure substance. Pure compound is a substance that consists of only one element.In other words, pure compounds are mostly homogeneous and contain only one type of atom or molecule.According to this, sodium, sugar and iron are three pure compounds. So, the number pure compounds are 
Conclusion
Reasons for incorrect options:
Option A: The number pure compounds are 
So, this is an incorrect option.
Option B: The number pure compounds are 
So, this is an incorrect option.
Option D: The number pure compounds are 
So, this is an incorrect option.

- There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm.
