What else can I help you with?
Which of the following is not required in a chemical reaction?
An enzyme is not required in a chemical reaction. While reactants, energy, and a chemical reaction pathway are essential components of a chemical reaction, enzymes can speed up the reaction but are not always necessary for it to occur.
Do all chemical reactions need atomic nuclei?
All atoms involved in a chemical reaction have an atomic nucleus.
What type of nuclear reaction releases energy through the combination of atomic nuclei, unlike fission reactions which involve the splitting of atomic nuclei?
The type of nuclear reaction that releases energy through the combination of atomic nuclei is called fusion. This is different from fission reactions, which involve the splitting of atomic nuclei.
Where is the energy which is released during a chemical reaction stored to begin with?
The energy released during a chemical reaction is stored in the chemical bonds of the reactant molecules before the reaction occurs. During the reaction, these bonds are broken, and new bonds are formed, releasing the stored energy in the process.
Nuclear what is the reaction that forms smaller atomic nuclei and releases atomic particles.?
The reaction that forms smaller atomic nuclei and releases atomic particles is called nuclear fission. In this process, a heavy atomic nucleus, such as uranium-235 or plutonium-239, splits into two or more lighter nuclei when it absorbs a neutron, accompanied by the release of energy and additional neutrons. These released neutrons can further induce fission in nearby nuclei, leading to a chain reaction. This reaction is the principle behind nuclear power generation and atomic bombs.
A nuclear reaction in which the nuclei of atoms join together is called nuclear fission.true or false?
False. Combining nuclei to form a new nucleus is called nuclear fusion. Nuclear fission is the splitting of an atomic nucleus.
An amtom undergoes a reaction ant attains a more stable from how do you know is it was chemical or nuclear reaction?
If an atom undergoes a chemical reaction, it involves rearrangement of electrons in the outer shell to form new chemical bonds. On the other hand, if it undergoes a nuclear reaction, it involves changes in the atomic nuclei, resulting in the formation of different elements or isotopes. To determine whether it was a chemical or nuclear reaction, observe whether there are changes in the electron configuration or in the atomic number and mass of the atom.
Where does the energy come from in a nuclear fission reaction?
In a nuclear fission reaction, the energy comes from the splitting of atomic nuclei.
The amount of energy released from a fission reaction is much greater than the energy released from a chemical reaction because in a fission reaction?
The amount of energy released from a fission reaction is much greater than that from a chemical reaction because fission involves the splitting of atomic nuclei, leading to a significant release of nuclear binding energy. This energy release is millions of times greater than the energy released in chemical reactions, which involve breaking and forming chemical bonds.
These pairs differ only by a proton?
The pairs differ by a single proton in their atomic nuclei, which affects their atomic number and chemical properties. For example, hydrogen and helium have different chemical behaviors even though they both have one proton in their nuclei.
How can you use the law of conversation of mass to help you balance a chemical equation?
Chemical reaction involve only the bonding between atoms- no atomic nuclei are affected. The law of conservation of mass in chemistry perhaps should be called the law of conservation of atoms!
What type of reaction does the hydrogen bomb use?
The hydrogen bomb uses nuclear fusion, a reaction in which two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy. This differs from nuclear fission, which is the process used in atomic bombs where heavy atomic nuclei are split into lighter ones.
