According to the molar concentration, volume in liters of 2 M KCl solution is 16.76 L.
What is molar concentration?
Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.
The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.
In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.
Volume required is obtained by molarity formula as, 2×74.55/2500=1/V=0.05964
∴V=1/0.05964=16.67 L.
Thus, 16.67 L of 2 M KCl solution contains 2.5 kg of KCl.

b. are one of the major symptoms of depression
c. usually also lead to panic attacks
d. should be ignored even when they last a long period of time
Answers
A) Sadness can occur within anybody, not just a symptom of depression. This option is out of the question, since it is wrong.
B) Feelings of sadness are usually linked to depression when felt over a long period of time. Studies say that sadness is only a little part of depression, while you mostly feel rejected, hopeless, and worthless. Looking at the other options, this would be the most reasonable answer.
C) This CAN be true in some ways, but panic attacks can be triggered by so many things. The #1 reason is usually when you're nervous or anxious. Panic attacks can even happen out of the blue. Sadness can lead to panic attacks, but not usually. I would say no for this option.
D) Sadness should NOT be ignored when they last over a long period of time. If you are sad for a certain time period, you should look into talking to somebody about the issue. This option is obviously false.
Out of the choices, two out of four were reasonable, but I would have to go with B) are one of the major symptoms of depression.

The substrate, enzyme pair from the citric acid cycle that is INCORRECT is E) Citrate, aconitase.
The citric acid cycle, also known as the Krebs cycle, is a crucial metabolic pathway for generating energy in cells. Each step involves specific substrates and enzymes. While all other options (A, B, C, and D) correctly match substrates and enzymes involved in the cycle, option E (Citrate, aconitase) is incorrect.
Aconitase is responsible for catalyzing the interconversion of citrate and isocitrate, not for the conversion of citrate itself. The correct pair for citrate is citrate synthase, which catalyzes the formation of citrate from oxaloacetate and acetyl-CoA.
Understanding these substrate-enzyme pairs is essential in comprehending the citric acid cycle's intricacies. Accurate knowledge of these reactions aids in grasping how cells produce energy through this pathway. This emphasizes the significance of precise knowledge of biochemical pathways for an accurate understanding of cellular processes.
In the context of cellular metabolism, identifying the correct enzyme for each substrate is vital for accurate biochemical analysis and the design of targeted interventions for metabolic disorders. Among the given options, the substrate, enzyme pair that is incorrect in the citric acid cycle is Citrate, aconitase.

Final answer:
The incorrect substrate-enzyme pair from the citric acid cycle is Oxaloacetate, citrate synthase.
Explanation:
The citric acid cycle, also known as the Krebs cycle or tricarboxylic acid cycle, is a series of chemical reactions that occur in the mitochondria of cells. It plays a crucial role in the aerobic respiration process, generating energy-rich molecules such as ATP.
The citric acid cycle involves the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. Each step of the cycle is catalyzed by a specific enzyme, which acts on a particular substrate.
The correct substrate-enzyme pairs in the citric acid cycle are as follows:
- Isocitrate, isocitrate dehydrogenase
- Succinyl CoA, succinate dehydrogenase
- Fumarate, fumarase
- Oxaloacetate, citrate synthase
- Citrate, aconitase
Therefore, the incorrect substrate-enzyme pair from the given options is D) Oxaloacetate, citrate synthase.
