They are attracted to one another because the magnetic fields link
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today
Answer:
mass composition is very essential in obtaining a balanced equation
Explanation:
to have a completely balanced equation that means the right hand side being your reactants must be equal to the right hand side being your product. both sides need to have equal mass composition, when calculating the mass composition make sure both sides are equal if not consider revisiting the number of moles on both sides to ensure they all balance
The masses of the 2 most
common isotopes of Cl are 35 and 37. Therefore we can formulate 3 possible
masses of Cl2:
<span>
35 + 35 = 70
35 + 37 = 72
37 + 37 = 74
<span>However, Cl 35 is the most common isotope of chlorine of the
two therefore it is the most probable that two Cl 35 atoms will combine, so 70
is the most common among all.

Nuclear Fusion.
Having low atomic nuclei is the reason why uranium-235 is not commonly found in large nuclear reactions.
So, scientist increases its concentration by fusing the lower atomic nuclei with high atomic nuclei in order to produce a heavier nucleus which will increase the release of energy.
