Balance the following equation and choose the quantity which is the sum of the coefficients of react

Question

Balance the following equation and choose the quantity which is the sum of the coefficients of reactants and products:
$ \ldots . \mathrm{PtCl}_4+\ldots . \mathrm{XeF}_2 \longrightarrow \mathrm{PtF}_6+\ldots \mathrm{ClF}+\ldots \mathrm{Xe} $

Professor PC Thomas Classes · Answer

(a) Balanced reaction is 
$ \mathrm{PtCl}_4+5 \mathrm{XeF}_2 \longrightarrow \mathrm{PtF}_6+4 \mathrm{ClF}+5 \mathrm{Xe} $
 ∴ Sum of stoichiometric coefficients 
$ =1+5+1+4+5=16 $
