Question

❤️HELLO❤️

80 cm3 of methane is mixed with 200 cm3 of pure oxygen at room temperature and pressure.The mixture is then ignited when it burns as illustrated by the equation:

CH4 + 2O2 gives CO2 + 2 H2O.

Calculate the composition of the resulting mixture if it is cooled to initial room temperature and pressure.

thanks......​

Answer 1

Answer:

Explanation:

CH4 + 2O2 gives CO2 + 2 H2O.

2 moles of ch4 gives 2 moles of co2 so  

co2 = 80cm^3
