How do the elements beryllium, carbon, and oxygen produce stars such as the Sun?
Answer:
Beryllium, carbon, and oxygen do not create stars like the sun. The sun is a massive cluster of hydrogen atoms being fused into helium atoms and heavier metals like Beryllium, carbon, and oxygen through the process of nuclear fusion. The more mass a star has in its core the more fusions that can occur and the heavier the metals inside can be fused into.

Which one of these is not an important structural feature found by the number of
electron rich regions
Hybridization
Bond Angles
Electronegativity
Electron Geometry
Answer:
Electronnegativity
Explanation:
There are three important structural features: Hybridization, Bond angels, and Electron Geometry.
The not so important structural feature found by the number of electron rich regions is electronegativity. Hence option c is correct.
What are structural feature?Structural feature is defined as the modeled as a directed acyclic graph (DAG), with the variable names as pathways and the variable values as nodes. The study of the construction of biological molecules is known as structural biology. Scientists study molecules in three dimensions using a range of imaging techniques to examine how they are put together, how they work, and how they interact.
Electronegativity is defined as the propensity for atoms involved in covalent bonds to draw the bonding electrons. The negatively charged electrons are drawn to the positively charged protons in the nucleus. The electronegativity or attraction will rise with the number of protons in the nucleus. Therefore, in a row of the periodic table, electronegativity rises from left to right.
Thus, the not so important structural feature found by the number of electron rich regions is electronegativity. Hence option c is correct.

C. The intramolecular bonds in ethanol are stronger than the intramolecular bonds in acetone.
D. The intermolecular forces in acetone are stronger than the intermolecular forces in ethanol.
Answer:
see below
Explanation:
1. The temperatures at which a substance changes phases indicate the relative strength of the forces between molecules in the substance.
2. solid, liquid, gas
3. The forces between water molecules break, and the bonds between the atoms in water are unchanged.
4. The forces strengthen, and the molecule structure becomes more rigid.
5. The intermolecular forces in ethanol are stronger than the intermolecular forces in acetone.
The the degree of intermolecular interaction between molecules determines the magnitude of boiling point of the substance.
During phase change, a substance moves from one state of matter to another. The temperature at which a phase change occurs is determined by the strength of the forces between molecules in the substance. The relative magnitude of intermolecular forces between molecules in different states of matter is solids > liquids > gases.
During boiling, energy is imparted to the molecules of a liquid. When this occurs, the forces between water molecules break, and the bonds between the atoms in water are unchanged.
We must recall that the molecules of a substance are in constant random motion. The average kinetic energy of molecules is proportional to temperature. As a sample of calcium carbonate is cooled, the forces between molecules strengthen, and the molecule structure becomes more rigid.
The magnitude of intermolecular interaction affects the boiling point of a liquid. The stronger the magnitude of intermolecular interaction,the higher the boiling point. As such, ethanol having hydrogen bonds between its molecules has a higher boiling point than acetone which only posses weaker dipole - dipole interactions.

How are sound and light similar? How are they different?
Answer:
Sound requires a medium to move through; light does not.
Sound and light are similar in that both are forms of energy that travel in waves.
Explanation:
Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Sound can only travel through a medium (substance) while light can travel through empty space. Sound is a form of mechanical energy caused by vibrations of matter.
Light waves DO NOT require a medium, they travel fastest in empty space; Sound waves REQUIRE a medium, they travel fastest in dense material like solids. Sound is a longitudinal wave.

HELP QUICK carbon dioxide makes up less than 1 percent of earths atmosphere, and oxygen makes about about 20 % These percentages are maintained most directly by what
Answer:
respiration and photosynthesis
Explanation:
The percentages of carbon dioxide and oxygen in Earth's atmosphere are maintained most directly by cellular respiration and photosynthesis.
What is photosynthesis?Photosynthesis simply refers to a biological and chemical process through which green plants convert light energy derived from the Sun into chemical energy, so as to make their food while using carbon dioxide (CO₂) and releasing oxygen.
On the other hand, cellular respiration is a series of metabolic reactions that occur in living cells and it involves the use of oxygen that are typically produced by green plants (autotrophs) during photosynthesis.
This ultimately implies that, the percentages of carbon dioxide (1%) and oxygen (20%) that are contained in Earth's atmosphere are maintained most directly by cellular respiration and photosynthesis.

Which best describes the energy change that takes place during deposition?
Heat energy released by the substance
Heat energy is maintained by the substance
Heat energy is slowly gained by the substance
Heat energy is quickly absorbed by the substance
Answer:
heat energy released by the substance
The energy change that takes place during deposition is that heat energy is released by the substance. This statement is true about deposition.
Deposition is a phase transition that occurs when a gas is converted directly to a solid without passing through the liquid state. During deposition, energy is released by the gas particles and absorbed by the surface, resulting in a decrease in the energy of the gas particles and an increase in the energy of the surface particles.As a result, the substance releases heat energy as it changes from a gas state to a solid state.
Therefore, the correct option is:Heat energy released by the substance.

The partial pressure of CO2 gas in a bottle of carbonated water is 4.60 atm at 25 ºC. How much CO2 gas (in g) will be released from 1.1 L of the carbonated water when the partial pressure of CO2 is lowered to 1.28 atm? At 25 ºC, the Henry’s law constant for CO2 dissolved in water is 1.65 x 103 atm, and the density of water is 1.0 g/cm3.
If the partial pressure of CO₂ in a bottle of carbonated water decreases from 4.60 atm to 1.28 atm, the mass of CO₂ released is 0.265 g.
The partial pressure of CO₂ gas in a bottle of carbonated water is 4.60 atm at 25 ºC. We can calculate the concentration of CO₂ using Henry's law.
[tex]C = k \times P = \frac{1.65 \times 10^{-3} M }{atm} \times 4.60 atm = 7.59 \times 10^{-3} M[/tex]
We can calculate the mass of CO₂ in 1.1 L considering its molar mass is 44.01 g/mol.
[tex]\frac{7.59 \times 10^{-3} mol}{L} \times 1.1 L \times \frac{44.01 g}{mol} = 0.367 g[/tex]
Now, we will repeat the same procedure for a partial pressure of 1.28 atm.
[tex]C = k \times P = \frac{1.65 \times 10^{-3} M }{atm} \times 1.28 atm = 2.11 \times 10^{-3} M[/tex]
[tex]\frac{2.11 \times 10^{-3} mol}{L} \times 1.1 L \times \frac{44.01 g}{mol} = 0.102 g[/tex]
The mass of CO₂ released will be equal to the difference in the masses at the different pressures.
[tex]m = 0.367 g - 0.102 g = 0.265 g[/tex]
If the partial pressure of CO₂ in a bottle of carbonated water decreases from 4.60 atm to 1.28 atm, the mass of CO₂ released is 0.265 g.
