Balanced chemical equation for the given reaction is Fe₂(CO₃)₃ + 6Cs → 3Cs₂CO₃ + 2Fe.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equations in which all entities are present in equal amount on reactant side as well as on product side.
Given balanced chemical reaction is:
Fe₂(CO₃)₃ + 6Cs → 3Cs₂CO₃ + 2Fe
Above given equation is a balanced chemical equation where all atoms of reactant as well as of products are present in same amount.
Hence, required balanced equation is Fe₂(CO₃)₃ + 6Cs → 3Cs₂CO₃ + 2Fe.

The valency of Al₂O₃ is 0 because each element in the compound has its outer most shell completely filled so it cannot obtain electrons of donate them since it is in its stable-most form.
Option C: elements produce spectra with only few distinct lines.
The spectra are not continuos and are different for every element. This permits to identify elements.
The two notations that represent isotopes of the same element is the one that represented in option 1
The lower number is the number of protons while the upper number is the atomic weight
