What is the molality of a solution of 0.25 moles of sucrose in dissolved in enough water to make 4.00 liters of water?

What temperature in kelvin does 60.5 liters of sulfur dioxide occupy if there are 2.5 mol at 0.75 atm??

7nadin3 [17]

The temperature in kelvin does 60.5 liters of sulfur dioxide occupy if there are 2.5 mole at 0.75 atm is 221.07 kelvin

Explanation
This is calculated using ideal gas equation, that is PV=nRT
where, P(pressure) = 0.75 atm
V(volume) = 60.5 L
n(moles) = 2.5 mole
R( gas constant) = 0.0821 L.atm/mol.k
T(temperature =?

by making T the subject of the formula
T is therefore =Pv/nR

T= (0.75 atm x 60.5 L) / ( 2.5 molex 0.0821 L.atm/mol.K) = 221.07 kelvins

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.

How do water molecules dissolve a salt?

Artist 52 [7]

Answer:

Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance.

B. What do you notice about the density of the sinking objects? Dense objects feel very heavy for their size

puteri [66]

Answer:

The answer is below

Explanation:

The density of an object is its mass per unit of volume. Dense objects feel very heavy for their size, while for objects with low density they are very light for their size.

Density is the ratio of mass to volume; it is given by:

Density (D) = mass (m) / volume (V)

An object sinks in water if the density of the object is greater than the density of water. While an objects floats on water if the density of the object is les than the density of water
