The correct description of electron sharing between two oxygen atoms is "Each oxygen shares two electrons with each other."

Each oxygen atom has six valence electrons. When they bond to form an oxygen molecule (O2), they share two electrons each, resulting in a double covalent bond. This sharing allows each oxygen atom to achieve a stable octet configuration, resembling the configuration of a noble gas. Therefore, the correct answer is that each oxygen shares two electrons with each other.

The path from ocean to river runoff involves evaporation, condensation, and precipitation in the water cycle, followed by surface runoff, snowmelt, or streamflow.

The path that moisture takes from the ocean to the runoff that forms a river involves several steps in the water cycle. The process begins with evaporation and sublimation of water from the ocean, which rises into the atmosphere. The moisture then condenses to form clouds and falls back to the Earth as precipitation. This precipitation can enter freshwater bodies or infiltrate the soil, and eventually make its way to the ocean through surface runoff, snowmelt, or streamflow.

C is obvious because no other choice has any closer answer

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.

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:

[tex][Na]=1s^22s^22p^63s^1[/tex]

Chlorine is the 17th element of the periodic table:

[tex][Cl]=1s^22s^22p^63s^23p5[/tex]

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

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.

If a cell is seriously deprived of water, this lack of water would most likely affect the cell’s enzymes because:

Both the plant and animal cell needs water in order to perform their basic functions which include transport of materials, waste distribution, production of genetic information, and many more.

As a result of this, we can see that there would be a serious problem if any of these cells are deprived of water which would lead to the cytoplasm and plasma membrane to partially shut down because they would not be able to engage in protein synthesis and other important functions.

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.

A solution of sodium chloride in water is indeed a good conductor of electricity.

A conductor refers to a material or substance that allows the flow of electric charges or current through it. Conductors have properties that facilitate the movement of electrons, which are negatively charged particles, within the material.

Now, the statement that describes sodium chloride based on the given information is:

A solution of sodium chloride in water is a good conductor of electricity. Sodium chloride, commonly known as table salt, consists of clear, colorless crystals.

When sodium chloride is dissolved in water, it dissociates into sodium ions[tex](Na^+)[/tex]and chloride ions [tex](Cl^-)[/tex].These ions are responsible for the conductivity of the solution. Since ions are charged particles, they can move freely in the solution and carry electric current.

Therefore, as a result, sodium chloride in water is a good conductor of electricity.

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.

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.
