What is the nuclear binding energy for oxygen-16?

Binding energy = 123.4 MeV

Therefore;

Proton mass: 1.00727 amu x 8 = 8.05816 amu

Neutron mass: 1.00866 amu x 8 = 8.06928 amu

Total                                               =  16.12744 amu

Mass defect = 16.12744 amu -15.9949 amu

                     = 0.1325 amu

Binding energy = 0.1325 amu x 931 MeV/amu

                          = 123.4 MeV

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

i'm pretty sure its b i might be wrong though!
