How do the chemical reactions in this lab activity compare to nuclear reactions, such as fission and fusion?

The chemical reaction has been the low energy reaction involving electrons rearrangement, while nuclear reactions have been the high energy reactions with change in nuclei.

The reactions can be the nuclear reactions when there has been the involvement of the change in the nuclei of the atom. However, the reaction has been termed as the chemical reaction when the change has been processed in the electrons with the rearrangement.

The nuclear reactions have consisted of a high amount of energy to be liberated, while the amount of energy involved in the chemical reaction has been smaller.

Thus, the chemical reaction has been the low energy reaction involving electrons rearrangement, while nuclear reactions have been the high energy reactions with change in nuclei.

Nuclear energy released in nuclear fission and fusion is much larger than chemical reactions because of the astonishing amounts of energy being released at one moment.

Explanation:

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
