What is the total energy q released in a single fusion reaction event for the equation given in the problem introduction? use c2=1.49×10−10j/u?

Explanation:

The fusion reaction in this problem is

The total energy released in the fusion reaction is given by

where

is the speed of light

is the mass defect, which is the mass difference between the mass of the reactants and the mass of the products

For this fusion reaction we have:

is the mass of one nucleus of hydrogen

is the mass of one nucleus of helium

So the mass defect is:

The conversion factor between atomic mass units and kilograms is

So the mass defect is

And so, the energy released is:

what question you dont ask a question

explanation:

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
