The main difference between the Bohr model of the atom and the wave-mechanical model of the atom lies in the level of certainty of where the electrons are located is true

Answer: metallic

Explanation: plato

To ground all static charges, metallic object is required.

Static charges are due to electrons. Static charges cause static electricity when electrons jump between substances with opposite charge. Grounding of static charges is done by wire being attached between container and water pipe or copper rod.

Total resistance is kept below one mega ohm .Static charges are greater in liquid state as molecules are loosely held by weak inter molecular forces of attraction.Static charges are controlled by controlling flow rate.

Static charges can be grounded by earthing which connects parts of electric power system to ground typically to earth's surface.It serves purpose of electrical safety and prevent static buildup.

Answer:

Type of bonding is represented in the figure is Ionic bonding.

Explanation:

[tex]Na^++Cl^-\rightarrow NaCl[/tex]

Type of bonding shown in the given figure is an Ionic bonding.

Ionic bonding is defined as bonding in which complete transfer of electrons takes place. Atom which looses electrons is known as electropositive atom and an atom which gains electrons is known as electronegative atom.

Sodium is the 11th element of the periodic table:

Sodium atom will donate an electron to gain noble gas configuration and chlorine atom needs an electron to gain noble gas configuration.

The table of contents generally starts at the beginning of a document, listing headings, subheadings, and their respective page numbers for easy navigation.

The table of contents in a book or document typically begins at the start of the document, following any front matter like a preface or introduction. It lists the report's headings and subheadings, along with the page numbers where these sections begin. In digital formats, such as online webbooks, the table of contents may be accessible from the book's homepage or a 'Contents' menu, providing links to different sections. When creating a table of contents in a word processor like Pages, you should place the insertion point at the beginning of the document and select 'Insert > Table of Contents' to ensure it captures all content. Often, digital formats will include interactive elements, allowing you to jump to specific parts of the text quickly.

Answer:18g

Explanation:

According to law of conservation of mass, the mass of product is 18 g when kept in a sealed container as mass is neither created nor destroyed rather it is restored at the end .

According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.

Outer core earth is composed primarily of liquid metal.  The surface layer of the Earth is made up of numerous moving slowly tectonic plates.

The third planet orbiting the Sun, Earth is home to all living species in the cosmos. While there is a lot of water everywhere across the Solar System, just Earth has liquid surface water. The ocean covers approximately 70.8% of the Earth's surface, dwarfing arctic ice, lakes, as well as rivers.

The remaining 29.2% of the Earth's surface is made up of land, which includes continents and islands. The surface layer of the Earth is made up of numerous moving slowly tectonic plates that interact to build mountain ranges, volcanoes, but instead earthquakes. Outer core earth is composed primarily of liquid metal.

Therefore, outer core earth is composed primarily of liquid metal.

Final answer:

The molar mass of oxygen gas (O₂) is found by multiplying the atomic mass of one oxygen atom (16.00 g/mol) by two, because oxygen is diatomic, yielding a molar mass of 32.00 g/mol.

Explanation:

To find the molar mass of oxygen gas (O₂), we need to consider that molecular oxygen is diatomic, meaning each molecule is composed of two oxygen atoms. The atomic mass of a single oxygen atom is approximately 16.00 g/mol. Therefore, the molar mass of oxygen gas is:

(2 atoms/molecule) × (16.00 g/mol/atom) = 32.00 g/mol

This calculation indicates that one mole of oxygen gas, which is 6.022 × 10²³ molecules, has a mass of 32.00 grams.

Final answer:

Whether an object scatters or reflects light depends on the object's surface properties and light's wavelength. Smooth, shiny surfaces lead to specular reflection, while rough surfaces or small particles cause light to scatter, as in Rayleigh scattering, which gives the sky its blue color.

Explanation:

The distinction between whether an object will scatter light or reflect light depends on the object's properties and the wavelength of light. Specular reflection, following the law that the angle of reflection is equal to the angle of incidence, usually occurs on smooth and shiny surfaces, like a mirror. On the other hand, diffuse reflection or scattering occurs when light encounters rough surfaces or particles much smaller than the light's wavelength, which is the principle behind Rayleigh scattering. Rayleigh scattering, inversely related to the fourth power of the light's wavelength, explains why blue light is scattered more in the atmosphere, making the sky look blue, and why the sun appears yellowish from Earth.

A closed system permits only energy to enter or exit, not matter.

A closed system is a fundamental concept in physics and chemistry. It is defined as a system where matter cannot enter or exit, but energy can still be exchanged with its surroundings. For instance, consider a beaker covered with a glass lid. While heat can pass through the glass, water vapor cannot escape, thus maintaining the amount of matter inside the beaker constant. This helps in studying various thermodynamic processes without the interference of external matter exchange.

Explanation:

As the total concentration is given as 1.2 mM. And, it is also given that salt present in the solution is NaCl.

As sodium chloride is an ionic compound so, when it is added to water then it will dissociate into sodium and chlorine ions as follows.

           [tex]NaCl \rightarrow Na^{+} + Cl^{-}[/tex]

So, it means in total there will be formation of 2 ions when one molecules of NaCl dissociates.

Therefore, concentration of chlorine ions will be calculated as follows.

       Concentration of [tex]Cl^{-}[/tex] ions = [tex]\frac{1.2mM}{2}[/tex]

                                                        = 0.6 mM

Thus, we can conclude that the concentration of chloride ions is 0.6 mM.

In a 1.2 mM solution of NaCl, which fully dissociates into its constituent ions in solution, the concentration of chloride ions is also 1.2 mM.

The concentration of chloride ions in a 1.2mM aqueous solution of NaCl can be determined by understanding that NaCl dissociates completely into its constituent ions in solution. For every molecule of NaCl, there is one sodium ion (Na+) and one chloride ion (Cl-).

Given that the total ion concentration in the solution is 1.2mM, and knowing that NaCl dissociates fully into Na+ and Cl-, we can infer that the concentration of each ion is also 1.2mM. Therefore, the concentration of chloride ions in the solution is 1.2 mM.
