Which of the following best describes a safety precaution needed in nuclear power plants? (1 point)

7 0

Nuclear power plants produce energy in terms of electricity from radioactive materials. These elements are highly unstable due to their high neutron-to-proton ratio. That's why they spontaneously decay by giving off sub-atomic particles which yields a new element. So, nuclear reactions, fission and fusion, produce 'clean' energy because they do not produce gaseous by-products that could harm the environment. They only yield radioactive materials that could be harmful to the health of people nearby the area. Because of this risk, safety precautions are needed in a nuclear power plant.

Smokestacks are no longer used in nuclear power plants because there are no gases. So, the first choice is eliminated. Next, you should NOT ventilate the radioactive materials. Remember this radiation travels through all types of matter so it is harmful. These type of materials are strictly contained and handled. The third choice is correct because it prevents radiation to reach the outside environment. The last option, on the other hand, is not justifiable. Before a nuclear power plant is approved by the government, it is made sure that all its employees and employers are inherently safe. Otherwise, it would not be put into operation.

Therefore, the answer is letter C.

Provide one example of how life on Earth would not be possible without water based on its characteristics.

snow_lady [41]

Answer: ice is less dense than liquid water. If ice was more dense, Earth would freeze.

Explanation: There are many reasons why life on Earth depends on the characteristics of water. One could discuss hydrogen bonds and its role as a solvent, but the unusual property of water is is the change in density with change in temperature. Water is densest at 4 degC, which is why ice floats - it is less dense than cold water (it melts quickly in warm water, so density isn’t impotant at higher temperatures). Most liquids are less dense than the solid, frozen form. If this was the case with water, any ice that formed would sink, and sease would freeze from the bottom up. Furthermore, the lowest layers would be insulated and would not all melt in summer. Thus over time, the seas would become a thin layer of liquid water at best, over solid ice. Life could not develop without liquid seas. In addition, ice is reflective, reducing the amount of sunlight absorbed, further reducing temperatures. Without ocean circulation, polar areas would be even colder, and there would be no rain.

Maybe use flash cards for them to understand or look up periodic table on line and show them.

How much heat is required to convert 2.55g of water at 28.0 degree celsius to steam 100 degree celsius

Crazy boy [7]

767.448 Joules of heat is required.
You use the equation Q=MCdeltaT
Make sure you convery celsius to Kelvin
Specific heat of water is 4.18
So it will be Q=2.55(4.18)(72)
Q=767.448

G the normal range of the ph of blood is between 7.35 and 7.45; variations beyond this range have significant health implication

Fiesta28 [93]

Answer : the hydrogen ion concentrations for pH = 7.35 and pH = 7.45 are 4.46 x 10⁻⁸ M and 3.54 x 10⁻⁸ M respectively.

When the pH of a solution is less than 7, the hydrogen ion concentration is higher and therefore the solution is acidic.

On the other hand, when the pH of a solution is greater than 7, hydroxide ion concentration is higher and the solution acts as a base.

The normal pH range of blood is given as 7.35 - 7.45 which is greater than 7. That means blood is slight basic in nature.

Let us find hydroxide ion concentration of blood.

$pH + pOH = 14$
