In a nuclear reaction, the total number of nucleons (protons and neutrons) in the system remains constant, adhering to the law of conservation of mass-energy. While the identity of the elements and the arrangement of nucleons may change, the overall mass-energy before and after the reaction is conserved according to Einstein's equation (E=mc^2). Additionally, the total charge is also conserved during the reaction.
What else can I help you with?
Is it that reaction distance increases with speed while the reaction time stays the same?
Yes, the reaction distances increases with speed while reaction time stays the same. for example the two-second rule.
Why does the mass stay the same when hydrogen burns in oxygen and water is made?
Law of conservation of mass: total mass of Reactants AND Products stays UNCHANGED during ANY reaction (except nuclear reactions like fusions)
Why are precipitation reactions also called double displacement reactions?
They aren't. Double displacement (metathesis) sometimes forms a precipitate, but not always, and it would be silly to call it a "precipitation reaction" if no precipitate was formed. Formation of a precipitate is, however, one way to tell that a reaction has occurred. If everything just stays in solution, then it's meaningless to call it a "reaction" since there has been no change. The evolution of a gas is another method for determining that a reaction has occurred, as is a change in color (this often indicates a change in oxidation state as well, though not always).
What goes around the world and stays in one place?
A stamp.
What stays the same in a physical change?
The chemical nature/identity of the substance stays the same when a physical change takes place.
What has two hands a round face always runs but stays in place?
A clock.
What is the kolea?
A kolea is a pacific golden plover... It always stays 1 place and comes back to the same place.....
What has two hands a big round face always runs but stays in place?
A clock.
Is it that reaction distance increases with speed while the reaction time stays the same?
Yes, the reaction distances increases with speed while reaction time stays the same. for example the two-second rule.
What stays constant in a chemical reaction?
In a chemical reaction, the total mass of the substances involved stays constant. This is known as the law of conservation of mass.
3 laws of motions?
For every action there is an equal and opposite reaction An object in motion stays in motion until a force acts upon it An object that is not in motion stays in place until a force acts upon it
Does Canada have nuclear weapons?
Plutonium is always produced by using uranium fuel in a nuclear reactor, but it stays in the spent fuel unless this is processed. I don't think Canada has any processing capability for separating out the plutonium, but you need to ask the question to the Canadian authority
How is the chain reaction in a nuclear reactor different from one in an atomic bomb?
In a nuclear reactor, the chain reaction is controlled to produce a steady flow of energy by regulating the rate of reactions. In an atomic bomb, the chain reaction happens rapidly and uncontrollably, resulting in a massive release of energy in a short period of time, leading to an explosion.
Is an atomic number always equal to the number of protons?
Yes, it is. The type of atom is defined by the atomic number. Usually, when an atom undergoes a chemical reaction, only the sharing/possession of electrons changes, and the number of protons (and so the atomic number of the element) stays the same. When an atom somehow undergoes a nuclear reaction, which is possible, the number of protons sometimes do change, but in that case the atomic number (and thus the element type) becomes different as well.
When a chemical reaction occurs what always stays the same between reactants?
In a chemical reaction, the total number of each type of atom in the reactants must equal the total number of each type of atom in the products. This is known as the law of conservation of mass.
How mass can be converted into energy. give examples?
Mass can not be converted into energy. This is a common misconception. The example usually given is nuclear reactions. Note that this is no different from a chemical reaction, except that the energies involved (as well as the mass deficit, see below) are much greater in a nuclear reaction.Assume that hydrogen is fused into helium, in the Sun. Some would say that "mass is converted into energy". This is not true. The mass deficit (see: "mass deficit" article in Wikipedia for more details) means that the helium has less mass than the hydrogen. However, any energy leaving the place of the reaction - for example, light leaving the Sun - also has mass! If the energy stays there, say as heat, it contributes to the total mass! Thus, total mass is conserved.As to the energy, the light that leave the Sun has a certain energy. This energy is available before the reaction, as nuclear energy; a type of potential energy. Thus, total energy is also conserved.Since both mass and energy are conserved, there is no mass-to-energy conversion. The same happens for other nuclear reactions, or any reaction for that matter. Both mass and energy are always conserved.
What stays the same but always changes?
nothing, atoms are always moving.
