A certain chemical reaction experiences a 7.50 x 10-7 kilogram loss in mass. If this mass were to be totally converted to energy, what would be the magnitude of that energy? (1 J = 1 kg m2/s2)

1.20 x 1023 J

2.5 x 109 J

4.00 x 101 J

6.75 x 1010 J

Answer 4

according to Einstein E=mc^2

E= energy
m= mass
c= speed of the light in the vacuum

E= 7.50 x 10-7 kilogram (3.0 x10^8 m/s)^2
E=6.75 x 1010 J

Answer 5

Gamma rays are unlike alpha and beta particles because gamma rays:

are more strongly deflected by electric or magnetic fields

have less energy than either alpha or beta particles

have more mass than either alpha or beta particles

have no effect on atomic number or mass number of the atoms that emit them
