the ratio of parent to daughter = 15.38 : 1
The radioactive disintegration is considered to be first order reaction.
The relation between first order rate constant and the half life is:
Let us calculate the rate constant from half life as
The rate law expression for first order reaction is
A0 = initial amount of rubidium isotope = say 100
At= final amount of rubidium isotope after 4.6 billion years
putting all values
The amount of daughter isotope formed =100-93.897 = 6.103
the ratio of parent to daughter = 93.897:6.103 = 15.38 : 1
< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
im pretty sure its b
a rubidium isotope has a half-life of almost 50 billion years. given that scient...
