Final answer:
In nuclear fusion, two or more atomic nuclei combine to form a new element or different atom (A), such as helium from hydrogen. Some of the mass is converted into energy, not resulting in pure energy only. Fusion powers stars and releases significant energy in the process.
Explanation:
The result of nuclear fusion reactions is (A) a new element or different atom formed from the original two. During a fusion reaction, two or more atomic nuclei collide at very high speed and join to create a new nucleus. An example of this process is the fusion of deuterium and tritium, light isotopes of hydrogen, which combine to form helium and release energy.
This energy release occurs because some of the mass of the fusing nuclei is converted into energy, following Einstein's mass-energy equivalence principle (E=mc²). Therefore, the result is not pure energy but a combination of a new element and released energy. Nuclear fusion is also the process that powers the stars, where hydrogen atoms fuse to form helium, releasing vast amounts of energy in the form of light and heat.
In summary, option (A) a new element or different atom formed from the original two is the correct result of a fusion reaction, as exemplified by the fusion reaction in stars.

d) a description of mass
find the molar mass of oxygen gas
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.

Why does a closed system mean that nothing could enter or exit
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.

One reactant with a mass of 10 grams is combined with another reactant with a mass of 8 grams in a sealed container. After the reaction, what is the most reasonable prediction for the total mass of the products of this reaction?
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 .
What is law of conservation of mass?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.

Sodium chloride is made up of clear, colorless crystals. A solution of sodium chloride in water is a good conductor of electricity. Which statement describes sodium chloride?
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.

Which of the following describes the electron sharing between two oxygen atoms?
Each oxygen shares two electrons with each other.
Each oxygen shares eight electrons with each other.
Each oxygen shares one electron with each other.
Each oxygen shares six electrons with each other.
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.

Describe the path that moisture takes from the ocean to the runoff that forms a river
The path from ocean to river runoff involves evaporation, condensation, and precipitation in the water cycle, followed by surface runoff, snowmelt, or streamflow.
Explanation: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.

an aqueous solution contains 1.2mM of total ions. if the solution is NaCl (aq), what is the concentration of chloride ions?
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.
Explanation: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.
