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.

Answer:
Explanation:
mass of one virus = 9.0 x 10⁻¹² mg
mass of one mole = 6.02 x 10²³ x mass of one virus
= 6.02 x 10²³ x 9.0 x 10⁻¹²
= 54.18 x 10¹¹ mg
= 54 x 10⁸ g .
= 54 x 10⁵ kg .
b )
let n be no of moles of virus that will be equal to weight of oil tanker
n x 54 x 10⁵ = 3 x 10⁷
n = 5.5555
rounding off to 2 significant figure
5.6 moles Ans .
