Question

Consider the completely balanced chemical equation for the roasting of Iron pyrites ($FeS_2$) with the lowest possible whole-number coefficients. What is the sum of the stoichiometric coefficients of the products?

Answer: C

💡 Solution & Explanation

The roasting reaction for iron pyrites is: $4FeS_2 + 11O_2 \xrightarrow{\Delta} 2Fe_2O_3 + 8SO_2$. The products are $Fe_2O_3$ and $SO_2$, with respective coefficients of 2 and 8. The sum of the product coefficients is $2 + 8 = 10$.
