Question

Which of the following reactions of methane is incomplete combustion? (A) 2CH4 + O2 xrightarrowCu/523 K/100 atm 2CH3OH (B) CH4 + O2 xrightarrowMo2O3 HCHO + H2O (C) CH4 + O2 → C(s) + 2H2O(l) (D) CH4 + 2O2 → CO2(g) + 2H2O(l)

Tardigrade Admin · Accepted Answer

CH4 + O2 → C(s) + 2H2O(l) is incomplete combustion. In complete combustion, hydrocarbons release CO2 and H2O whereas in this reaction, C and H2O are released.

Q. Which of the following reactions of methane is incomplete combustion?

$2 C H_{4} + O_{2} C u /523 K /100 a t m 2 C H_{3} O H$

$C H_{4} + O_{2} M o_{2} O_{3} H C H O + H_{2} O$

$C H_{4} + O_{2} \to C_{(s)} + 2 H_{2} O_{(l)}$

$C H_{4} + 2 O_{2} \to C O_{2 (g)} + 2 H_{2} O_{(l)}$

$C H_{4} + O_{2} \to C_{(s)} + 2 H_{2} O_{(l)}$ is incomplete combustion. In complete combustion, hydrocarbons release $C O_{2}$ and $H_{2} O$ whereas in this reaction, $C$ and $H_{2} O$ are released.

Q. Which of the following reactions of methane is incomplete combustion?

2CH4​+O2​Cu/523K/100atm​2CH3​OH

CH4​+O2​Mo2​O3​​HCHO+H2​O

CH4​+O2​→C(s)​+2H2​O(l)​

CH4​+2O2​→CO2(g)​+2H2​O(l)​

CH4​+O2​→C(s)​+2H2​O(l)​ is incomplete combustion. In complete combustion, hydrocarbons release CO2​ and H2​O whereas in this reaction, C and H2​O are released.

$2 C H_{4} + O_{2} C u /523 K /100 a t m 2 C H_{3} O H$

$C H_{4} + O_{2} M o_{2} O_{3} H C H O + H_{2} O$

$C H_{4} + O_{2} \to C_{(s)} + 2 H_{2} O_{(l)}$

$C H_{4} + 2 O_{2} \to C O_{2 (g)} + 2 H_{2} O_{(l)}$

$C H_{4} + O_{2} \to C_{(s)} + 2 H_{2} O_{(l)}$ is incomplete combustion. In complete combustion, hydrocarbons release $C O_{2}$ and $H_{2} O$ whereas in this reaction, $C$ and $H_{2} O$ are released.
