How much water has to be evacuated from 250ml of 1M Ca(OH)2 to make it 3M

Which statement is true about this reaction?

lubasha [3.4K]

Answer:

A) It is a practical source of energy on Earth.

Explanation:

The reaction shown is a nuclear fusion reaction. Nuclear fusion refers to the combination of two light nuclei to produce a heavier nuclei with a release of tremendous amount of energy. The energy released in a fusion reaction is so great and it is often difficult to achieve fusion reactions in a controlled nuclear reactor.

Fusion reactions just like the one shown is the source of energy on earth. The energy reaching the earth is obtained by fusion reactions in outer space.

Predict the products of the electrolysis of molten nickel(II) iodide. Write an ionic half-equation for the formation of one of t

Daniel [21]

Answer:

See explanation

Explanation:

The electrolysis of nickel(II) iodide yields nickel solid and iodine gas.

In the oxidation half equation;

2I^-(aq)-------> I2(g) + 2e

In the reduction half equation;

Ni^2+(aq) + 2e -----> Ni(s)

These are the half equations of the process;

The overall equation is;

Ni^2+(aq) + 2I^-(aq)-------> NiI2

You need a 35% alcohol solution. on hand, you have a 405 ml of a 30% alcohol mixture. you also have 80% alcohol mixture. how muc

Bumek [7]

You must add 45 mL of the 80 % alcohol to the 30 % alcohol to get a 35 % solution.

You can use a modified dilution formula to calculate the volume of 80 % alcohol

V1×C1 + V2×C2 = V3×C3

Let the volume of 80 % mixture 1 = x mL. Then the volume of the final 35 % mixture 3 = (405 + x ) mL

(x mL×80 % alc) + (405 mL×30 % alc) = (405 + x)mL × 35 % alc

80x + 12 150 = 14 175 + 35 x

45x = 2025

x = 2025/45 = 45

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.
