Determine the number of moles of aluminum in 2.154 x 10-1 kg of Al. Group of answer choices 5816 mol 7.984 mol 6.02 X 1023 mol 4

Jlenok [28]

Answer:

Avogadro's number is 1 mol = 6.02 * 10^23 elements

It means that 1 mol of atoms is 6.02 * 10^23 atoms

1 mol of atoms = 6.02 * 10^23 atoms

From there, if you divide both sides by 1 mol of atoms, you get

1 = 6.02 * 10^23 atoms / 1 mol of atoms.

That means, that to pass from a number of moles of atoms to number of atoms you have to multipby by the conversion factor

6.02*10^23 atoms Al/ 1 mol Al

That is the second option of the list.

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.

Given: f(x) 3x-1. g(x) 2x^2-3

Blizzard [7]

<h3>Solution:</h3>

f(x) = 3x - 1 = 0

f(x) = x = 1/3

By putting the value of x in g(x), we get

g(x) = 2(1/3)^2 - 3

g(x) = 2(1/9) - 3

g(x) = 2/9 - 3

g(x) = -25/9

<h2>Answer:</h2>

g(x) = -25/9

If you need to produce X-ray radiation with a wavelength of 1 Å. a. Through what voltage difference must the electron be acceler

earnstyle [38]

Answer:

12.4×10^3 V

Explanation:

From E=hc/wavelength= eV

The voltage becomes

V= hc/e* wavelength

V= 6.63*10^-34*3*10^8/1.6*10^-19*1*10^-10

Note that the energy of the photon is transferred to the electron. That is the basic assumption we have applied in solving this problem. The kinetic energy of the electron is equal to the product of the electron charge and the acceleration potential.
