Question
Chapter 3, Problem 3.51UTC
Interpretation Introduction
To determine:
Identification of each figure as element, compound or mixture.
Expert Solution & Answer
Answer to Problem 3.51UTC
Solution:
- it is a compound
- it is a mixture
- it is an element
Explanation of Solution
- A pure substance that can be separated into other smaller substances by any means that is by chemical or physical is said to be a compound. When the bonded atoms are same then the substance is said to be a molecule whereas when the joined atoms are different then they are said to be compound.
- It consists of 2 different types of atom. Thus, it is a compound.
- A material made up of two or more different substances which are not combined chemically is said to be a mixture.
- It consists of different atom and compound. Thus, it is a mixture.
- A substance that is made up of completely one type of atom is said to be an element.
- Same atom combines to form an element and it is presented as a single molecule or an atom just like ?? atom.
Conclusion
- compound
- mixture
- element

Using reaction free energy to predict equilibrium composition
Consider the following equilibrium:
2NOCI (g) 2NO (g) + Cl2 (g) AGº =41. kJ
Now suppose a reaction vessel is filled with 4.50 atm of nitrosyl chloride (NOCI) and 6.38 atm of chlorine (C12) at 212. °C. Answer the following questions
about this system:
?
rise
Under these conditions, will the pressure of NOCI tend to rise or fall?
x10
fall
Is it possible to reverse this tendency by adding NO?
In other words, if you said the pressure of NOCI will tend to rise, can that
be changed to a tendency to fall by adding NO? Similarly, if you said the
pressure of NOCI will tend to fall, can that be changed to a tendency to
rise by adding NO?
yes
no
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of NO needed to reverse it.
Round your answer to 2 significant digits.
