Answer: 25.8 g of
will be produced from the decomposition of 73.4 g of
Explanation:
To calculate the moles :

The balanced chemical reaction is:
According to stoichiometry :
2 moles of
produce = 3 moles of 
Thus 0.242 moles of will produce=
of 
Mass of
= 
Thus 25.8 g of
will be produced from the decomposition of 73.4 g of
So the question ask to separate the reaction of the element if your problem into its component half reaction and the best answer or the elements are the following: (Cs-> Cs+ + 1e-) x2 and <span>2e-+Cl2->2Cl-. I hope you are satisfied with my answer and feel free to ask for more </span>
