Mass relationships in chemical reaction.
For the combustion of methane, beginning with 3.15 mole of CH4.
How many moles of CO2 are obtained when the CH4 is completely combusted? solve this
The balanced equation for the combustion of methane is:
CH4 + 2O2 -> CO2 + 2H2O
This means that for every one mole of CH4 that reacts, one mole of CO2 is formed. Therefore, if we start with 3.15 moles of CH4, we can expect to obtain 3.15 moles of CO2 when the reaction is complete.
