Stability of atoms is determined by neutron:proton ratio. This n/p ratio is 1:1 for elements below atomic number 20. Hope this helps.
C
Decomposition is of this form: A becomes B+C ... so after the reaction, the element A DECOMPOSES into two smaller elements, B and C.
Synthesis is the opposite: B+C becomes A AFTER THE REACTION.
Hope that helps :))
You need the unit of g however you must convert to moles before you can use the mole ratio to find the moles of iron, you used the molar mass of iron to find the grams of iron. since F e 2 o 3
Answer:
19.32
Explanation:

d=342.93g/17.75cm
=19.32g/cm
i hope this helps
