Homework Statement Nucleus A has rest mass m_A,collides with nucleus B which has rest mass m_B.In the laboratory frame,nucleus A has energy E>m_Ac^2 and nucleus B is stationery.After the collision,a nuclear reaction takes place: A+B\rightarrow C+D where nucleus C has rest mass m_C and...

If you light a match to a mixture of oxygen and hydrogen which then reacts explosively to form water. Is it a chemical or nuclear reaction? I know a chemical reaction is one in which a substance is changed into one or more new substances. A nuclear reaction is one in which a new element...

In chemical reactions the individual elements present in the reactants are the same as in the products of the reaction. Is this true for nuclear reaction? My attempt Nuclear reactants produce new products, and a new element can be made. This means that a new element with different proton and...

From my experience one cannot under go a nuclear reaction of a material by heat alone, so why does charcoal, which all i have heard is carbon, yeild potassium and sodium compounds when heated? :mad:

Homework Statement Fission - Nuclear Reaction ( Characteristics, Examples aND Concerns) The attempt at a solution Characteristics: - 1. Heavy nucleus splitting into two or more lighter nuclei. 2. Fission Nuclear Reaction produced large amount of energy Examples: - Nucler Bombs...

complete data of question: a nitrogen nucleus N(A=14,Z=7) bombared with an alpha particle of a certain energy transmutes to an oxygen nucleus(A=17,Z=8) and a proton a:write a equation for this nuclear reaction b:find the minimum energy of alpha particle to make this reactin occur (mass of...

Homework Statement When (6 3)Li (i.e. 3 neurtrons and 3 protons) is bomarded with protons a nuclear reaction may occur in which an alpha particle is produced. What is the other product of this reaction? Write an equation for this reaction. Homework Equations conservation laws The...

How much more energy is in a nuclear reaction than a chemical reaction.

How much more energy is in a nuclear reaction than a chemical reaction.

I remembered my teacher once said that a proton can be a neutron or the other way round but i am not too sure about it so my friend propose that neutron --> proton + electron. i am not too sure about this so can anyone tell me if this is true. If this is true, i calculate that the mass defect...

# Neutrons bombard nuclei of N(14,7) converting it into Li(7,3). The process is accompanied by the emission of: 1)4 protons and 4 neutrons 2)6 protons and 2 electrons 3)1 alpha particle, 2 protons and 1 neutron 4)2 alpha particles and gamma ray photon I get 2 solutions here. N(14,7) +...

How should I explain the particle which has the lower nucleon number will undergo fusion reaction while the partivle which has the higher nucleon will undergo fission reaction? Thanks.

Ok i have a question that I've been wondering about for a while here... One of my chemistry professors stated to the class that E=mc^2 means that energy is transferred through light, sound, and heat. Now i was under the impression that 1, heat is light... and sound was simply particle...

Here I have a problem: A 232/92 Uranium nucleus emits an alpha particle with kinetic energy=5.32MeV. What is the final nucleus and what is the approximate mass(in units) of the final atom. I can write the equation for the reaction, this will give 4/2 He and 228/90 Th. If the alpha particle...

Is it true that 'during' a nuclear reaction such as in our sun that there is a (period of time?) in which matter is in a state of chaos? I ask for a reason. IF IT WERE SO that 'matter' was in a state of chaos, is there a period of time when that space-time cannot be defined as either matter...
