What is the volume (L) occupied by a mole of an ideal gas,

irina [24]

Answer:

29.2 L

Explanation:

Given data

Moles (n): 1 mol

Pressure (P): 0.824 atm

$626mmHg.\frac{1atm}{760 mmHg} =0.824atm$

Temperature (T): 293 K

We can find the volume of the gas (V) of the using the ideal gas equation.

P × V = n × R × T

V = n × R × T / P

V = 1 mol × (0.0821 atm.L/mol.K) × 293 K / 0.824 atm

V = 29.2 L

Why the phospholipids are found in large amount in liver, brain and blood?

alekssr [168]

Answer:

Phospholipids are carried in the blood and deposited in vital tissues such as the brain and the liver where they serve as protection to these vital organs.

Explanation:

Lipids is another name for fats. These fats play many crucial roles in the body. Phospholipids are water soluble fats. They are important in building the protective barrier, or membrane, around body cells. In blood and other body fluids, these phspholipids usually form structures that enclose fat and carry it throughout the bloodstream to the organs where they are stored in the body.

These phospholipids also play an important role of serving as a protection to vital organs in the body such as the liver and brain. Hence, a large amount of phospholipids are found in the liver and brain where they serve as protection to these vital organs.

Advances in medical technology and healthcare have increased the life expectancy of people around the world. what negative effec

Ghella [55]

The negative effect of technology on Healthcare:

Impersonal treatment, harmful health impacts, higher expenditures, the potential for overuse, and privacy violations are just a few of the negative effects of medical technology.

Medical technology:

It refers to all technological tools or apparatus utilized to protect human life. Medical equipment such as an insulin pump, a wireless brain sensor, a blood glucose meter, a digital thermometer, pulse oximeters, smart inhalers, etc the tools which had helped patients receive better medical treatment.

Effects of Medical technology:

Medical technology, nevertheless, can potentially cause issues for the patient like:

1. Impersonal treatment: When a healthcare professional uses technology too frequently, they could spend less time getting to know the patient as a person and more time dealing with the equipment.

2. Harmful health impacts: Surgery, radiation therapy, and chemotherapy are a few examples of treatments that might be advantageous but also have risks.

3. Higher expenditures: Due to the research and marketing required to bring new technologies to market and to generate a profit for their creators and manufacturers, they may result in increased patient costs.

4. Potential for overuse: The use of a technology or new product by a medical professional may be encouraged by the manufacturer, regardless of whether it is in the patient's best interest.

5. Privacy violation: Electronic medical records (EMR), for example, collect and manage patient information. This new technology is convenient, but it also has the potential to be misused, compromising patient privacy and personal data.

Calculate the pH at of a 0.10 Msolution of anilinium chloride . Note that aniline is a weak base with a of . Round your answer t

notsponge [240]

The question is incomplete, here is the complete question:

Calculate the pH at of a 0.10 M solution of anilinium chloride $(C_6H_5NH_3Cl)$ . Note that aniline $(C6H5NH2)$ is a weak base with a $pK_b$ of 4.87. Round your answer to 1 decimal place.

Answer: The pH of the solution is 5.1

Explanation:

Anilinium chloride is the salt formed by the combination of a weak base (aniline) and a strong acid (HCl).

To calculate the pH of the solution, we use the equation:

$pH=7-\frac{1}{2}[pK_b+\log C]$

where,

$pK_b$ = negative logarithm of weak base which is aniline = 4.87

C = concentration of the salt = 0.10 M

Putting values in above equation, we get:

$pH=7-\frac{1}{2}[4.87+\log (0.10)]\\\\pH=5.06=5.1$

Hence, the pH of the solution is 5.1

Which of the following aqueous solutions has the lowest pH? Why?

jenyasd209 [6]

Answer:

HCI

Explanation:

The solution with the lowest pH is HCI with a pH value of 1. It is understood that it is more acidic because it is a strong acid.
