Reactants - Products Reactants Products 10 SEP Use Mathematics Using the table of average bond energies, estimate
the energy needed to break the bonds of the reactants and the energy
released when the products form for the reaction N2 + O2 2NO. Note:
N2 has a triple bond and O2 and NO have double bonds.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
