This is answer open this image I am not sure is this wright
Answer: a) 
Explanation:
As we know that,
where,
q = heat released = -600.2 J
= mass of iron rod =100 g
= final temperature =
= initial temperature = ?
= specific heat of iron = 
Now put all the given values in equation, we get
![-600.2J=100\times 0.452J/g^0C\times (25.0-T_{initial})^0C]](https://tex.z-dn.net/?f=-600.2J%3D100%5Ctimes%200.452J%2Fg%5E0C%5Ctimes%20%2825.0-T_%7Binitial%7D%29%5E0C%5D)
Therefore, the initial temperature of iron rod was
By using it for a long time lol.
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.

<span>The third equivalence point is not observed in the titration curve of phosphoric acid because the specific point is concealed due to the rapid ionization of water which in turn forms an hydroxide ion and a molecule called hydronium molecule. The pH value changes more at the first and second points.</span>
