Development is the result of society's capacity to organize resources to meet challenges and opportunities. Society passes through well-defined stages in the course of its development. They are nomadic hunting and gathering, rural agrarian, urban, commercial, industrial, and post-industrial societies.

Which describes the molecule shown below?

lana [24]

Answer:

Option D. Saturated alkane

Explanation:

To know which option is correct, it is important that we know what saturated and unsaturated compounds are in this context.

Saturated hydrocarbons are compounds which has only carbon to carbon single bonds (C–C) in its chain. A very good example of such compound is the Alkanes.

Unsaturated hydrocarbons are compounds which has either a carbon to carbon double bond (C=C) or a carbon to carbon triple bond (C≡C) in its chain. Examples of such compounds include alkenes and alkynes.

Now, let us answer the question given above bearing the meaning of saturated and unsaturated compounds in mind.

The compound given above contains only carbon to carbon (C–C) single bond.

Therefore, the compound is a saturated alkane.

viktelen [127]

Actual question from source:-

A 3.96x10-4 M solution of compound A exhibited an absorbance of 0.624 at 238 nm in a 1.000 cm cuvette. A blank had an absorbance of 0.029. The absorbance of an unknown solution of compound A was 0.375. Find the concentration of A in the unknown.

Answer:

Molar absorptivity of compound A = $1502.53\ {Ms}^{-1}$

Explanation:

According to the Lambert's Beer law:-

$A=\epsilon l c$

Where, A is the absorbance

l is the path length

$\epsilon$ is the molar absorptivity

c is the concentration.

Given that:-

c = $3.96\times 10^{-4}\ M$

Path length = 1.000 cm

Absorbance observed = 0.624

Absorbance blank = 0.029

A = 0.624 - 0.029 = 0.595

So, applying the values in the Lambert Beer's law as shown below:-

$0.595=\epsilon\times 1.000\ cm\times 3.96\times 10^{-4}\ M$

$\epsilon=\frac{0.595}{3.96\times 10^{-4}}\ {Ms}^{-1}=1502.53\ {Ms}^{-1}$

Molar absorptivity of compound A = $1502.53\ {Ms}^{-1}$

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.
