The transmutation of a radioactive uranium isotope, 234/92 u, into a radon isotope, 222/86 rn, involves a series of three nuclear reactions. at the end of the first reaction, a thorium isotope, 230/90 th, is formed and at the end of the second reaction, a radium isotope, 226/88 ra, is formed. in both the reactions, an alpha particle is emitted. write the balanced equations for the three successive nuclear reactions. show all work.

Answer : The balanced equations for the three successive nuclear reactions are:

First reaction will be:                

Second reaction will be:                  

Third reaction will be:                    

Explanation :

Alpha decay : In this process, alpha particles is emitted when a heavier nuclei decays into lighter nuclei. The alpha particle released has a charge of +2 units.

The general representation of alpha decay reaction is:

The balanced equations for the three successive nuclear reactions are:

First reaction will be:                

Second reaction will be:                  

Third reaction will be:                    

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

d. air pressure decreases as altitude increases.
