Answer:
<u>Reaction is called exergonic when ΔG is negative i.e. ΔG < 0</u>
Explanation:
The Gibbs free energy represents the spontaneity or feasibility of a given chemical reaction at constant pressure and temperature and is given by the equation:
ΔG = ΔH - TΔS
Here, ΔG - change in the Gibbs free energy
ΔS - change in the entropy
ΔH - change in the enthalpy
T - temperature
If the value of <u>ΔG for a chemical reaction is positive i.e. ΔG > 0</u>, then the given chemical reaction is said to be nonspontaneous. Such a reaction is called endergonic.
Whereas, if the <u>ΔG value for a chemical reaction is negative i.e. ΔG < 0</u>, then the given chemical reaction is said to be spontaneous. Such a reaction is called exergonic.
Answer:
1-Fluoro-4-nitrobenzene
Step-by-step explanation:
Step 1. Identify the substituents on the ring,
The groups are <em>fluoro</em> and <em>nitro</em>. They have no priority as functional groups, so the base name is <em>benzene</em>.
Step 2. Identify their relative priorities.
F and NO₂ have no functional group priority, so we list them in alphabetical order. F has <em>alphabetical priority </em>over NO₂. The name becomes <em>fluoronitrobenzene</em>.
Step 3. Number the atoms of the ring.
The C atom bearing the F is <em>C1.</em> Count around the ring, and the NO₂ group is on <em>C4</em>.
Step 4. Name the compound.
Insert the locating numbers <em>immediately in front</em> of the substituents. Use <em>hyphens</em> to join letters to numbers.
The name becomes 1-fluoro-4-nitrobenzene.
Answer:
The correct answer is 372852.9 g.
Explanation:
First, we must look for the relationship between the masses in grams and pounds.
To get an approximate result, the relationship between pounds and grams found is:
1 lbs = 453.592 g
Now we must use this relationship as a conversion factor in the following way:
8.22 lbs *
= 372852.9 g
The mass expressed in grams for 8.22 lbs is 372852.9 g.
Have a nice day!
Answer:
No.
Step-by-step explanation:
When looking at numbers after the decimal point, think of the numbers as real numbers.
In 1.25, think of the .25 as just 25.
Since this is after the decimal point, it is 25 of a 100.
Now, is 25 closer to 4 or not?
Of course, the number has a great distance from 4.
