Answer: 1. Nuclear power plants operated at full capacity more than 92% of the time in 2020—making it the most reliable energy source in America. That's about 1.5 to 2 times more reliable as natural gas (57%) and coal (40%) plants, and roughly 2.5 to 3.5 times more reliable than wind (35%) and solar (25%) plants.

2. Used nuclear fuel can be recycled to make new fuel and byproducts. More than 90% of its potential energy still remains in the fuel, even after five years of operation in a reactor.

3. FuelGems produces a revolutionary, powerful, multi-action fuel additive that reduces harmful greenhouse emissions and saves fuel. The revolutionary additive uses tiny micro-doses of carbon-based nanoparticles to reduce the damaging effects on the environment.

4. U.S. nuclear plants can employ up to 700 workers with salaries that are 30% higher than the local average. They also contribute billions of dollars annually to local economies through federal and state tax revenues. A strong civilian nuclear sector is essential to U.S. national security and energy diplomacy.

5. Nuclear power plants operated at full capacity more than 92% of the time in 2020—making it the most reliable energy source in America. That’s about 1.5 to 2 times more reliable as natural gas (57%) and coal (40%) plants, and roughly 2.5 to 3.5 times more reliable than wind (35%) and solar (25%) plants.

6. The use of nuclear energy for electricity generation can be considered extremely safe. Every year several hundred people die in coal mines to provide this widely used fuel for electricity. There are also significant health and environmental effects arising from fossil fuel use.

7. A 2015 study of 22 countries found that, at a discount rate of 10 percent, the median cost of both natural gas and coal was lower than nuclear energy, while at a discount rate of 3 percent, nuclear energy was the most economical option in all countries analyzed.

8. Nuclear plants are the most efficient source of electricity, operating 24/7 at a 93 percent average capacity factor

9. Often ranked as one of the most efficient energy sources, wind energy is harnessed all over the world. Of course, some spots are known as being windier than others, and companies typically make use of these spots by building wind farms filled with turbines there. Wind energy has also been used for hundreds of years.

Discuss the classical bonding model which best explains the bonding in the compound nah2po4
Ipatiy [6.2K]

The classical bonding model which best explains the bonding in the compound NaH₂PO₄ is Hydrogen bonding.

<h3>What is Classical bonding model ?</h3>

By classical, we mean models that do not take into account the quantum behavior of small particles, notably the electron.

These models generally assume that electrons and ions behave as point charges which attract and repel according to the laws of electrostatics.

Sodium dihydrogen phosphate (NaH₂PO₄) is monoclinic, In which, the four independent hydrogen atoms were located on a difference map; they are involved in four O … O Hydrogen-bonds of length 2.654 (2), 2.589 (2), 2.559 (2), and 2.500 (2) Å.

The short contact (2.500 Å), which is not astride any symmetry element, is of the type O-H … O (asymmetrical).

The distorted coordination polyhedra of the sodium atoms are discussed in the light of recent theories on electrostatic balance.

Hence, the classical bonding model which best explains the bonding in the compound NaH₂PO₄ is Hydrogen bonding.

A column is packed with 0.5 g of a strongly acidic ion exchange resin in H+ form. A 1.0 M NaCl solution is passed through the co
Lena [83]

Answer:

The correct answer is 17 meq/g

Explanation:

Ion exchange capacity (IEC) express the total of active sites of a resin in which ions are attached because the greater molecular weight.

The exchange Reaction can be represented as

R-HR-H^{+} +  Na^{+} + Cl^{-} -> R-Na^{+} + HCl_{aq}

The IEC value (in meq/g) is determinated by using the next equation:

IEC=[(mL of NaOH)*(M of NaOH)]/mass of resin

IEC [(17 mL)*(0.5 M)/0.5]= 17 meq/g

Please ignore my answers because they are wrong.

Answer:

The wavelength of the radio wave is 3.003 m.

The energy of the radio wave is 6.6194\times 10^{-26} J.

Explanation:

Frequency of the radio waves, ν = 99.9 MHz = 99.9\times 10^6 Hz

Wavelength and frequency are related to each other by realtion:

\lambda =\frac{c}{\nu }

\lambda = Wavelength of the wave

c = speed of the light

ν = Frequency of the wave

\lambda =\frac{3\times 10^8 m/s}{99.9\times 10^6 s^{-1}}=3.003 m

The wavelength of the radio wave is 3.003 m.

The energy of the electromagnetic wave is given by Planck's equation:

E=h\times \nu

h = Planck's constant = 6.626\times 10^{-34} Js

The energy of the radio wave with 99.9 MHz frequency will be:

E=6.626\times 10^{-34} Js\times 99.9\times 10^6 s^{-1}

E = 6.6194\times 10^{-26} J

The energy of the radio wave is 6.6194\times 10^{-26} J.

What is a limitation of using a chemical formula, such as C6H12O6, to represent a compound?
Kaylis [27]
The chemical formula does not show how the atoms are connected to one another.
When we write the chemical formula of any substance, we are not able to understand the spatial arrangement of that substance's atoms. This is extremely important in organic compounds, which exhibit different physical characteristics as well as different chemical characteristics due to the way their atoms are arranged in space. These isomers are known as enantiomers.

Identify the examples of diffusion in the list below. Check all that apply.
Fynjy0 [20]

Answer;

  • A teacher takes the cap off a permanent marker. A few minutes later, students at the back of the classroom complain about the odor of the marker.
  • A cooking school student burns a piece of toast. Soon, the entire kitchen smells like burnt toast.
  • Toxic fumes produced by a chemical factory are detected in the air in a town several miles away.
<h3><u>Explanation;</u></h3>
  • Diffusion is a type of passive transport that involves the movement of particles from a region of high concentration to a region of low concentration.
  • <em><u>Diffusion takes place in liquids and gases, since their particles can move randomly from one region to another.</u></em>
  • <em><u>Therefore, diffusion results from the random movement of particles in which the net movement is down the concentration gradient  that is, from a region of high concentration to a region of low concentration.</u></em>
