Mass defect and Binding energy Flashcards
1
Q
what is the binding energy
A
energy released is all the protons, neutrons and electrons were brought together
2
Q
what is the mass defect
A
the mass of the atom minus the expected mass from number of protons, neutrons and electrons.
3
Q
what equation do we use for finding how much energy is equivalent to the mass defect
A
E = mc^2
4
Q
how much energy is it to brake a hydrogen bond
A
15kJ mol-1
5
Q
how much energy is it to burn one mole of butane
A
2.86x10^3 kJ mol-1
6
Q
how to I find the binding energy when I have the energy of 1 atom
A
multiply the energy by avogardos number which will give us the binding energy per mole.
7
Q
what is avogadros number
A
6.022x10^23
8
Q
what is binding energy measured in
A
kJ mol-1
9
Q
what is the mass defect measured in
A
kg
