Chapter 4, Problem 1E
How do the properties of compounds compare to the properties of the elements from which they are composed?
Expert Solution & Answer
Interpretation Introduction
To determine:
How the properties of compounds compare to the properties of elements from which they are composed.
Answer to Problem 1E
Solution:
The properties of a compound and its elements vary completely from the elements that make it up.
Explanation of Solution
The combination of elements in fixed and definite proportions results in formation of compound.
The properties of compounds are different to the properties of elements from which they are composed. The combination of two or more elements results in formation of completely new substance. For example, water is formed by hydrogen and oxygen, but water is in liquid state under standard conditions while hydrogen and oxygen are in a gaseous state. So, we can say that the properties of a compound and its elements vary completely from the elements that make it up.
Conclusion
The properties of compounds cannot be compare to the properties of elements from which they are composed because a compound is very different to the elements from which it is composed.

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.
