Which of the following is NOT a benefit of
using renewable energy sources?

The option that is the structural units that make up ionic solids is option   D. Ions

Ionic solids are made up of ions, which are atoms or groups of atoms that have a positive or negative charge due to the gain or loss of electrons. In ionic solids, the positive ions (cations) are typically formed by metal atoms, while the negative ions (anions) are typically formed by nonmetal atoms. The ions in ionic solids are held together by electrostatic forces of attraction, called ionic bonds.

Therefore, These bonds are formed when the electrons from the outermost energy level of the metal atom are transferred to the outermost energy level of the nonmetal atom, creating a stable compound.

More energy then closer electrons.

Explanation:

As electrons move away from the nucleus, their energy increases.

Explanation:

Answer:

METHOD 1: (surface area of a solid reactant)  METHOD 2: (concentration or pressure of a reactant)

Explanation:

METHOD 1: (surface area of a solid reactant) Increasing the surface area of a solid reactant exposes more of its particles to attack. This results in an increased chance of collisions between reactant particles, so there are more collisions in any given time and the rate of reaction increases.

METHOD 2: (concentration or pressure of a reactant) Increasing the concentration means that we have more particles in the same volume of solution. This increases the chance of collisions between reactant particles, resulting in more collisions in any given time and a faster reaction. As we increase the pressure of reacting gases, we increase the rate of reaction.

Answer:

(b) Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

Explanation:

According to the law of conservation of mass, matter can neither be created nor be destroyed. However, it can be transformed from one form into another. During chemical reactions, atoms or ions are exchanged between reactants to form products. Thus, all the stoichiometric calculations are based on law of conservation of mass.

During redox reactions, one species is oxidized and other species is reduced. This involves electron transfer.

Explanation:

If the container is composed of a low-grade metal, the metal's poisons may seep into the food that is kept in it. This is why stainless steel is frequently advised because it is the least reactive and typically regarded as safe for food storage.

Why is food storage so essential?

By preventing deterioration, proper food storage not only helps you get the most out of your food budget but also preserves the nutritional worth and quality of the goods you buy. Additionally, safe food storage can aid in preventing hazardous bacteria-caused foodborne illnesses.

Answer: Any force that causes an object to move in a circle is called centripetal force.

your answer is D. physical change, because a new substance is not formed.

The boiling process  is considered to be a physical change as no new substance is formed.

Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.

Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.

They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

Answer: 5.0 M NaCl

Explanation:

A concentrated solution is one which has more amount of solute in it.

A dilute solution is one which has less amount of solute in it.

Molarity is defined as the number of moles of solute present per liter of the solution.

0.5 M NaCl will have 0.5 moles of NaCl in 1 L of the solution, 0.005 M NaCl has 0.005 moles of NaCl in 1 L of the solution, 0.05 M NaCl has 0.05 moles of NaCl in 1 L and 5.0 M NaCl has 5 moles of NaCl in 1 L.

Thus 5.0 M NaCl will be most concentrated.

Answer: There are [tex]4.05\times 10^{24}[/tex]  molecules in 6.73 moles of phosphorus trichloride

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

1 mole of [tex]PCl_3[/tex] contains = [tex]6.023\times 10^{23}[/tex]  molecules

Thus 6.73 moles of [tex]PCl_3[/tex] contains = [tex]\frac{6.023\times 10^{23}}{1}\times 6.73=4.05\times 10^{24}[/tex]  molecules

Thus there are [tex]4.05\times 10^{24}[/tex]  molecules in 6.73 moles of phosphorus trichloride

Explanation:

Answer:

The new volume of the gas is 42.28 mL.

Explanation:

Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law can be expressed mathematically as follows:

[tex]\frac{P}{T}=k[/tex]

where k = Constant

Boyle's law says that "The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure." This law is expressed mathematically as:

P * V = k

Finally, Charles's Law indicates that as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T}=k[/tex]

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:

[tex]\frac{P*V}{T}=k[/tex]

Studying an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{P1*V1}{T1}=\frac{P2*V2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{740 mmHg*36 mL}{306 K}=\frac{1750 mmHg*V2}{850 K}[/tex]

Solving:

[tex]V2=\frac{850 K}{1750 mmHg} *\frac{740 mmHg*36 mL}{306 K}[/tex]

V2= 42.28 mL

The new volume of the gas is 42.28 mL.

The bonding in NaCl involves a sodium ion and a chloride ion while the bonding in sodium metal involves sodium ions and a sea of electrons.

NaCl involves sodium and ion and chloride ion held together by an ionic bond. The sodium atom transfers an electron to chlorine atom to yield the chloride ion. This ion pair exists in the compound called sodium chloride.

In sodium metal, the sodium cations interact electrostatically with a sea of electrons in a metallic bond. Hence, while the bonding in sodium chloride involves an ion pair, the bonding in sodium metal involves sodium ions and a sea of electrons.

chemical energy

Explanation:

This energy process is called exothermic when the reactants are at a higher energy level as compared to the products while it is an endothermic process if the reactant require energy to form products.

The covalent bonds that bring atoms together in the form of molecules store potential energy. This is commonly referred to as chemical energy.

When two different elements bond together to form compounds , the covalent bonds initial present are broken and new bonds are formed .

The energy level of the new formed compound will be lower than the individual atom as the difference in energy level of both the elements is released as heat.

This energy process is called exothermic when the reactants are at a higher energy level as compared to the products while it is an endothermic process if the reactant require energy to form products.

Answer: Your friend is incorrect.

Explanation: If we have an object or something that isn’t moving, (let’s say a notebook on a desk). If there is change, and the notebook moves, there is acceleration. Force = Mass times acceleration, f = m*a. There has to be a force, first of all. If you touched the notebook and moved it, some of your energy is transferred and now the notebook has kinetic energy. If our system is you and the notebook, the total energy doesn’t change. the energy is transferred, but doesn’t change. Your friend is not correct. Please give brainliest hope this helped!
