An organic compound is oxidized by heating it with cupric oxide () to estimate its carbon and hydrog — Qualitative and Quantitative Analysis Chemistry Question
Question
An organic compound is oxidized by heating it with cupric oxide ($CuO$) to estimate its carbon and hydrogen content. For a compound with the general formula $C_xH_yN_z$, what is the stoichiometric coefficient of $CuO$ required for complete combustion?
Answer: A
💡 Solution & Explanation
The general balanced combustion reaction with Cupric oxide is: $C_xH_yN_z + (2x + \frac{y}{2})CuO \rightarrow xCO_2 + \frac{y}{2} H_2O + \frac{z}{2} N_2 + (2x + \frac{y}{2})Cu$. Thus, the stoichiometric coefficient is $2x + \frac{y}{2}$.
