Answer:
Nuclear energy powers our businesses, homes and military. America’s 95 operating nuclear reactors generate approximately 20% of our nation’s electricity and provide over half of our carbon-free energy. They also create good-paying jobs at power plants and uranium mines. Wyoming produced 87% of America’s domestic uranium supply in 2018.
Today, nuclear energy faces serious hurdles. Regulatory costs and subsidies for renewable energy technologies are forcing America’s nuclear power plants to close at an alarming rate.
Russia and China are subsidizing their government-owned nuclear companies to assert their energy influence around the world. China is searching the globe for uranium reserves and investing heavily in the countries where it’s found. They want to secure more nuclear fuel for themselves and increase their control of the global supply.
Meanwhile, American nuclear power plants have come to rely on cheap Russian imports of uranium to meet their nuclear fuel needs. Right now, roughly 40% of the uranium coming into the United States originates in Russia or its satellite states of Kazakhstan and Uzbekistan. Russian-backed companies are developing fuel that can be placed directly in American reactors.

Model A is better than Model B as Model A shows the three-dimensional shape of the molecule, but Model B does not. The correct option is c.
What are molecules?The smallest particle of a substance possesses all of its physical and chemical properties. One or more atoms make up a molecule.
Knowing the molecular weights of the molecules allows us to calculate their sizes. The molecular weight of a molecule is the sum of the atomic weights of the atoms in the molecule.
The relative atomic mass of particles determines their size. Particles with a higher relative atomic mass weigh more than particles with a lower relative atomic mass. Larger atoms have heavier iotas and a larger relative atomic mass.
Therefore, the correct option is c, Model A shows the three-dimensional shape of the molecule, but Model B does not.

How many moles are there in 32.4 grams of Na
According to the mole concept, there are 1.4087 moles in 32.4 grams of sodium.
What is a mole?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.
Number of moles in this case is obtained by dividing mass by molar mass that is, 32.4/23=1.4087 moles.
Thus, there are 1.4087 moles in 32.4 g of sodium.

balloon to 17.0 L?
0.301 moles
Further explanationAvogadro's hypothesis:
In the same T,P and V, the gas contains the same number of molecules
So the ratio of gas volume will be equal to the ratio of gas moles
Given
n₁=initial mol of Helium : 0.42
V₁=initial volume : 9.9 L
V₂=final volume : 17 L
Required
number of moles added
Analysis
Use formula :
[tex]\tt \dfrac{V_1}{n_1}=\dfrac{V_2}{n_2}[/tex]
Solution
[tex]\tt n_2=\dfrac{n_1\times V_2}{V_1}\\\\n_2=\dfrac{0.42\times 17}{9.9}\\\\n_2=0.721~moles[/tex]

Tenemos un cuerpo de 40 g cuya densidad es 1,24 g/mL y otro objeto de 70 g con una densidad de 0,96 g/mL. Si introducimos cada uno en un recipiente con agua, ¿en qué caso subirá más el nivel de líquido?
Answer:
El nivel de líquido subirá más al introducirse el objeto de 70 g.
Explanation:
El nivel de líquido subirá más con el objeto que tenga mayor volumen.
Por lo tanto vamos a calcular el volumen de ambos objetos, usando la definición de densidad:
Densidad = Masa / VolumenSi despejamos Volumen:
Volumen = Masa / DensidadAhora usamos esa ecuación y calculamos los volúmenes:
Objeto 1 ⇒ 40 g ÷ 1,24 g/mL = 32,26 mL Objeto 2 ⇒ 70 g ÷ 0,96 g/mL = 72,92 mLPor lo tanto el nivel de líquido subirá más con el segundo objeto.
