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.

what is the pH of a solution prepared from solid, neutral 2-nitrophenol providing a fromal concentration of 0.0353M, given that
REY [17]

Answer:

pH = 4.34

Explanation:

pH= -1/2(logKa) -1/2(log C)

= -1/2( log 5.98*10^-8) -1/2(log 0.0353)

=-1/2(-7.22)-1/2(-1.45)

=3.61+0.725= 4.34

2. In Experiment SOL, you investigated the solubility of oxalic acid. Sodium oxalate, Na2C2O¬4, is the sodium salt of this acid.
AnnZ [28]

Answer:

Sodium oxalate is a basic salt. In water it can be dissolved and dissociated.

The oxalic acid in water has two dissociations.

Explanation:

Na2C2O4 ---> 2Na+   +  C2O4-2

Sodium oxalate is the conjugate base of a weak acid. In water this salt, dissociates completely giving rise to the sodium and oxalate ions. As Na+ comes from a strong base, in water it does not produce hydrolysis while oxalate does react in water, because it takes a proton from it and it generates a basic hydrolysis releasing OH-.

C2O4-2  + H2O ⇄  HC2O4-  +  OH-

In water the salt is basic.  The pH of an aqueous solution of this salt is basic, since OH- is generated.

The HC2O4- has a second hydrolisis, it takes another proton from water to form oxalic acid.

HC2O4-  +  H2O ⇄  H2C2O4  +  OH-

The oxalic acid acts as a weak acid, it can release 2 protons to water, to make oxalate (its conjugate base).

H2C2O4  + H2O ⇄ H3O+  + HC2O4-

HC2O4-  +  H2O ⇄  H3O+  C2O4-2

The  HC2O4-  acts as an ampholyte since it accepts and delivers protons simultaneously.
