Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or the absorption of energy. This difference in mass arises due to the difference in atomic binding energy between the nuclei before and after the reaction. Fusion is the process that powers active or main sequence stars and other high-magnitude stars, where large amounts of energy are released.

A fusion process that produces nuclei lighter than iron-56 or nickel-62 will generally release energy. These elements have relatively small mass per nucleon and large binding energy per nucleon. Fusion of nuclei lighter than these releases energy (an exothermic process), while fusion of heavier nuclei results in energy retained by the product nucleons, and the resulting reaction is endothermic. The opposite is true for the reverse process, nuclear fission. This means that the lighter elements, such as hydrogen and helium, are in general more fusible; while the heavier elements, such as uranium, thorium and plutonium, are more fissionable. The extreme astrophysical event of a supernova can produce enough energy to fuse nuclei into elements heavier than iron.

Answer:

Nuclear fusion is when atoms (usually Hydrogen) collide together to form a new atom. For example, on the Sun, it's so hot that Hydrogen atoms crash into each other, forming new Helium atoms.

Hopefully, this helps! :D

Describe the difference between extensive and intensive properties
never [62]

Answer:

Intensive and extensive properties are both physical properties. However, intensive properties dont depend on the amount of matter present in a sample, whereas extensive properties do. Intensive properties only depend on the type of matter, such as color, temperature, or solubility. Extensive properties depend on the amount of matter, such as mass, volume or energy

Anna71 [15]

Answer:

An atom is made of protons and neutrons which make up the nucleus and electrons that are around the nucleus. Although almost all the mass of an atom is in the nucleus, most of the space that the atom takes up is occupied by the electrons.

In very simple terms, the electrons are in orbits around the nucleus so most of the volume of the atom is empty space within the volume that the electrons occupy. The behaviour of the electrons is often assumed to be orbits but their actual positions are not that simple.

As a final note, all atoms contain neutrons with the exception of hydrogen which can exist as one proton and one electron.

Locate the ion that has no change in oxidation number in redox reactions.
natali 33 [55]

a. Spectator ions are the ones that are present but does not enter into the actual chemical  reaction.

b. Na⁺ and NO₃⁻ ions are spectator ions involved in this above mentioned reaction

<u>Explanation:</u>

  • In redox reactions, for example reaction of aqueous silver nitrate and aqueous sodium chloride, silver chloride settles down as a precipitate by the addition of Ag⁺ ion from AgNO₃ and Cl⁻ ions from NaCl .
  • The other 2 ions that is NO₃⁻ ion and Na⁺ ion in the reaction do not enter into the reaction and they are called as Spectator ions.

This can be expressed as the following equation,

AgNO₃(aq) + NaCl(aq) →AgCl(s) + NaNO₃
