So,
Let's draw the structures for the following hydrocarbons:
Cyclohexane
We can draw it using the fact that it is a cycloalkane with six carbons:
Cyclohexene
It also contains six carbons with a hexagonal form, but the difference is that there's double bond on it:
Benzene
It has six carbons but there's an alternating double bond as follows:
Toluene
It has the same structure as benzene but it is bonded to a methyl group outside the benzene:
Answer:
-1.82 °C
Explanation:
Step 1: Given data
- Mass of NaCl (solute): 33.9 g
- Mass of water (solvent): 578 g = 0.578 kg
- Freezing point depression constant for water (Kb): -1.82 °C/m
Step 2: Calculate the molality of the solution
We will use the following expression.
m = mass of solute / molar mass of solute × kg of solvent
m = 33.9 g / 58.44 g/mol × 0.578 kg
m = 1.00 m
Step 3: Calculate the freezing point depression (ΔT)
The freezing point depression is a colligative property that, for a non-dissociated solute, can be calculated using the following expression:
ΔT = Kb × m
ΔT = -1.82 °C/m × 1.00 m
ΔT = -1.82 °C
A. 8,330 --> 8.33 × 10^3
B. 83.3 --> 8.33 × 10^1
C. 0.00833 --> 8.33 × 10^-3
D. 0.0833 --> 8.33 × 10^-2
E. 83,330 --> 8.33 × 10^4
Hope this helps!

Many of the men may believe that they are fair and unbiased against women.
Many of the women may already believe that they face biases.
<h3>What is confirmation bias ?</h3>
The propensity to seek for, understand, favor, and remember information that supports or confirms one's preexisting opinions or values is known as confirmation bias. People exhibit this bias when they choose facts that support their opinions while rejecting those that contradict them or when they interpret ambiguous facts as supporting their preexisting beliefs. Although confirmation bias cannot be completely avoided, it can be controlled, for instance, by critical thinking education and training.
Confirmation bias has been linked to poor decisions in the scientific, organizational, financial, and political spheres. These biases can preserve or reinforce views in the face of contradictory data and contribute to overconfidence in personal opinions.
