Answer:
1.31 X 10^ -10 joules per Fe 56 atom
Explanation:
The mass of a proton is 1.673 × 10-24 g. The mass of a neutron is 1.675 × 10-24 g. The mass of the nucleus of an 56Fe atom is 9.289 × 10-23 g. What is the nuclear binding energy (in J) for 56Fe? (c = 3.00 × 108 m/s)
some of the theoretical mass will be converted to binding energy
by Einstein's famous relativity equation
E = mc^2
where E is in joules, m is in Kgm. c is in m/sec
56Fe is element 26 so it has 26 protons and 56 -26 =30 neutrons
its theoretical nuclear mass is
(26 X 1.673 X 10^-24) + (30X1.675 X 10^-24) =
(43.498 X 10^-24) + (50.250 X 10^-24)=
93.748 X 10^24 gm
but its actual mass is 9.289 X 10^-23 g or
92.289 X 10^-24 g
the mas defect is the theoretical mass minus the actual
1.459 X 10^-24 gm =^
1.459 X 10^-27 Kgm
c = 3.00 X 10* m/s=
so joules of binding energy = (1.459 X 10^-27) X 9 X10^16)
1.31 X 10^ -10 joules per Fe 56 atom
Energy Levels of Electrons. As you may remember from chemistry, an atom consists of electrons orbiting around a nucleus. ... They are restricted to orbits with only certain energies. Electrons can jump from one energy level to another, but they can never have orbits with energies other than the allowed energy levels.
A. Organic catalysts are called enzymes.
Explanation:
The true statement of all is that organic catalysts are called enzymes. For example, saliva in the mouth is made up of different enzymes which are secreted in the human body.
- Catalysts reduces the activation energy and makes reaction proceed very fast. They generally increase the rate of chemical reactions.
- Catalysts like temperature affects the rate of chemical reaction. Chemical reactions increases as temperature increases.
- Catalysts in the human body are very useful because they help chemical reactions in the body to proceed at a much faster rate.
