The rate at which radioactive decay occurs & how much radioactive decay has occurred
AleksAgata [21]3 years ago
4 0

Answer:   How much radioactive decay has occurred

Explanation:  Radiometric dating is the source to determine the absolute age and time of the rocks.

Because the radioactive isotopes are unstable, They break down into several fragments over the time until they become a stable isotope.

Thus in order to accurately determine the absolute time, one should must know how much radioactive decay has occurred .

What is the concentration, in mass percent (m/m), of a solution prepared from 50.0 g nacl and 150.0 g of water?
Nataly [62]
Mass of solute ( m1 ) = 50.0 g

mass of solvent ( m2 ) = 150.0 g

Therefore:

m/m = ( m1 / m1 + m2 )

m/m = ( 50.0 / 50.0 + 150.0 )

m/m = ( 50.0 / 200 )

m/m = 0.25

Describe the location of the negative charges of the atom in j.j thompsons plum pudding model
iren2701 [21]

The location of the negative charges is evenly distributed throughout the entire atom.

J. J. Tomson concluded that atoms are divisible and that the corpuscles are their building blocks.

Atoms are made up of smaller particles.

J. J. Thomson discovered the electron ( the negative charges of the atom) in 1897.

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge and evenly distributed throughout the entire atom.

With this model, he abandoned his earlier hypothesis that the atom was composed of immaterial vortices.

Later, Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate.
