Question

A) write a balanced equation for the combustion of gaseous methane into gaseous carbon dioxide, and gaseous water. B)Suppose 0.410kg of methane are burned in the air at a pressure of exactly 1atm and temperature of 13.0C. Calculate the volume of CO2 gas that is produced.

A) write a balanced equation for the combustion of gaseous methane into gaseous carbon dioxide, and gaseous water.

Explanation / Answer

CH4 (g) + 2O2 (g) ---> Co2 (g) + 2H2O (l)

Mole ratio of CH4 : Co2 = 1:1

mass of CH4 = 0.410 Kg = 0.410 *1000 g

moles of CH4 = mass /molar mass CH4 = 0.410 *1000 /16 = 25.625 moles

Mole ratio of CH4 : Co2 = 1:1

so moles of Co2 = 25.625 moles

Calculate the volume of CO2 gas that is produced.

V= nRT/ P

T= 13.0C = 13 +273 = 286 K

R= 0.08206 Latm /K*mol

V= 25.625 * 0.08206 *286 / 1 atm = 601.39 L or 0.60139 ml CO2 (answer)
