g Identify the process in which the entropy increases. Group of answer choices a decrease in the number of moles of a gas during

liraira [26]

Answer:

phase transition from a solid to a gas

Explanation:

Entropy refers to the degree of disorderliness in a system. The more disorderly a system is, the greater the entropy of the system.

Decrease in the number of moles of a gas decreases the entropy of the system. Similarly, the entropy of solids is less than that of liquids. The entropy of liquids is less than that of gases.

Therefore, a change of phase from solid to gas represents an increase in entropy of the system.

Figure 2 represents part of the structure of graphite.

Paul [167]

The answers include the following:

Graphite conducts electricity because it has delocalised electrons which makes it possible for the electrons to move freely.

Graphite is slippery because it has layers which makes it possible for the atoms to slide over each other.

<h3>What is Graphite?</h3>

This is referred to as an allotrope of carbon and it is the most stable form. it is used in the production of substances such as pencil, electrode etc.

Graphite is able to conduct electricity because of the presence of delocalized electrons and is slippery due to its atoms being able to slide over one another.

Complete Question

The complete question is shown on the first uploaded image

Answer:

The calculation and filling of the table based on the ratio indicated by the column is shown on the second uploaded image

1 This is True

2 This is False

3 This is False

4 This is True

5 This is True

Explanation:

Based on your calculations, indicate whether each statement is True (T) or False (F):

Considering the first statement

Looking at the question we can see that the first statement is TRUE this because all the three experiment have different initial concentration (3.5,3.0 & 2.6)

Considering the second statement

Looking at table we can see that the second statement is FALSE because

the ratio value of [NO2]/ [N2O4] in all three experiment have different value 1.4 , 1.5 & 1.7 is not a constant value.

Considering the Third statement

Looking at the table we can see that the third statement is FALSE this is because the ratio value of 2[NO2]/ [N2O4] in all three experiment have different value 2.7, 3.0 & 3.3 is not a constant value.

Considering the Fourth statement

Looking at table we can see that the fourth statement is TRUE this is because the ratio value of $[NO2]^{2}/ [N2O4]$ in all three experiment have same value 3.9, 3.9 & 3.9 is a constant value.
