This chemical reaction shows that two molecules of hydrogen peroxide (H 0.) break
apart to form two molecules of water (H.0) and one molecule of oxygen (0,1
How does the arrangement of atoms and bonds
change?

Due to removal of oxygen and number of hydrogen bonds.

Explanation:

The arrangement of atoms and bonds change due to removal of oxygen molecule from hydrogen peroxide forming water which has one oxygen less than hydrogen peroxide. In hydrogen peroxide, four identical hydrogen bonds are formed with Oxygen while on the other hand, in water, two atoms of hydrogen attached by covalent bonds to the same atom of oxygen.

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
