Answer:
Atoms will rearrange and for new substances
Explanation:
In a chemical reaction, elements combine their atoms and create new substances. For this to occur, the bonds must break and form new ones with the other atoms.
Answer:
half-life=T= 36.9 years
Explanation:
As we know that
N
(
t
)
=
N
(
0
)
⋅
0.5
^(t/
T
)
N
(
0
)
=the number of atoms you start with=20 gram
and N
(
t
)= the number of atoms left=0.625 grams
after a certain time=t=184.5 years
T=half life of a nuclide=?
Putting value in above equation we get
half-life=T= 36.9 years
