A Lewis structure is a two-dimensional representation of a molecule that does not necessarily show what shape that molecule would take in three dimensions. From the given Lewis structure and what you know about VSEPR theory, identify the shape of the molecule. A molecule with atom Y single bonded with 2 X substituents. The Y atom has two lone pairs.

Answers

Answer 1

Answer:

Orbital geometry is Tetrahedral

Molecular geometry is Bent/V shape

Explanation:

Using the VSEPR theory which states that

The shape of a molecule depends upon the number of valence shell electron pairs  (bonded or nonbonded) around the central atom. Pairs of electrons in the valence shell repel  one another since their electron clouds are negatively charged. These pairs of electrons tend to occupy such positions in space that minimize  repulsion and thus maximize distance between them. The valence shell is taken as a sphere with  the electron pairs localizing on the  spherical surface at maximum distance  from one another. A multiple bond is treated as if it is a single  electron pair and the two or three electron  pairs of a multiple bond are treated as a single super pair. Where two or more resonance structures  can represent a molecule, the VSEPR  model is applicable to any such structure

so we have Y as the central atom and it has 2X substituents on its either sides with two lone pairs on Y. This is a case of Y which has

2 bonds with X on either sides

2 lone pairs on Y

The orbital geometry will be Tetrahedral but its Molecular geometry will be Bent/V shaped

The formula of the compound will be YX2

Water with chemical Formula of H2O bears the same features.

Answer 2

The shape of the given molecule according to the VSEPR theory has been Bent/V shape.

VSEPR theory has been the Valence Shell Electron Pair Repulsion theory. It helps in the determination of the molecular and geometrical shape based on the presence of the atoms attached.

The given molecule has the presence of 2 single-bonded X atoms.

The atoms repel each other, while the presence of loan pairs results in the force for the molecule to occupy the tetrahedral orbital geometry. The repulsion from the loan pair to the X atoms acquires the Bent V shape as molecular geometry.

B. They make energy.
C. They use carbon dioxide.
D. They form tissue that moves.

Answer:

I believe it's D

Explanation:

they both are worked a lot and it makes the most sense.

The cells in both bicep muscle and heart muscle make energy for contraction and relaxation. Hence, option B is correct.

What is cardiac muscles ?

Cardiomyocytes have a rather rectangular form and are short and thin. They have a single nucleus, cell organelles that are identical to those seen in skeletal muscle cells, and many sarcosomes, which supply the energy needed for contraction.

Intercalated discs with gap junctions for diffusion and communication link cardiomyocytes structurally. Myofibrils, which in turn are composed of thick and thin myofilaments, make up the sarcoplasm.

Due to their high energy needs, skeletal muscle cells have many mitochondria that enable them to produce enough ATP. Therefore, the cells in the bicep muscles and cardiac muscles produce energy.

Which of the following phrases best describes this reaction?
A Endothermic, absorbing energy
B) Endothermic, releasing energy
C) Exothermic, absorbing energy
D) Exothermic, releasing energy

Answers

The following phrases best describe this reaction : A Endothermic, absorbing energy

Further explanation

Delta H reaction (ΔH) is the amount of heat change between the system and its environment  

(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)  

∆H positive (endothermic): energy (heat) is absorbed from the environment to the system

∆H negative (exothermic): energy (heat) released from the system to the environment

Reaction

H₂O(g) + energy ⇒ H₂(g) + 1/2O₂(g)

In this reaction, it is shown that to break the bonds on the H₂O molecule to form H₂ and O₂ molecules will require energy (breaking the bonds requires energy)

This energy is usually called ∆H dissociation⁰

The dots are arranged on the four sides in pairs.

Oxygen is made up of 6 valence electrons, and since the ion has a net negative charge, the hydrogen and oxygen achieved their stable configuration this way.

how many atoms are there in 8.08 moles of carbon dioxide

Answers

Answer:

145.97×10²³ atoms

Explanation:

Given data:

Number of moles of CO₂ = 8.08 mol

Number of atoms of CO₂ = ?

Solution:

1 mole of CO₂ contain 1 mole C atom.

8.08 mole contain 8.08× 1 = 8.08 mole of C atom.

1 mole of CO₂ contain 2 moles of O atom.

8.08mole contain 8.08×2 = 16.16 mole of O atom.

Total number of moles of atoms = 8.08 mole + 16.16 mole

Total number of moles of atoms = 24.24 mol

Number of atoms of CO₂:

1 mole of any substance contain 6.022×10²³ atoms.

24.24 mol ×6.022×10²³ atoms / 1 mol

145.97×10²³ atoms

Molar mass
NaCl: 58.44g/mol
KCl: 74.55g/mol
LiCl: 42.39g/mol​

Answers

Answer:Mole Fraction of NaCl=0.5697

Explanation:

No OF Moles of NaCl=  Mass / Molar mass

=21.7 g/58.44g/mol

=0.371moles

No OF Moles of KCl=  Mass / Molar mass

=3.74g/74.55g/mol

=0.0502moles

No OF Moles of LiCl=  Mass / Molar mass

=9.76 g/42.39g/mol

=0.230moles

Mole Fraction of NaCL = Moles of NaCL/ Total number of moles of the mixture

=0.371/( 0.371+ 0.0502+0.230)

0.371/0.6512

=0.5697

Answer:

Mole fraction: 0.570

Explanation:

Mole fraction is defined as the ratio of moles of a compound in a mixture over the total moles of the mixture. To solve this problem, we need to find moles of the 3 salts:

Moles NaCl -Molar mass: 58.44g/mol-:

21.7g NaCl * (1mol / 58.44g) = 0.3713 moles

Moles KCl -Molar mass: 74.55g/mol-:

3.74g KCl * (1mol / 74.55g) = 0.0502 moles

Moles LiCl -Molar mass: 42.394g/mol-:

9.76g LiCl * (1mol / 42.394g) = 0.2302 moles

Mole fraction NaCl:

0.3713mol / (0.3713mol + 0.0502mol + 0.2302mol) =

0.570

Is nuclear energy poised to be part of America’s future?

Answers

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.
