Question

In the equation, CH4+2O2 -> CO2 +2H2O , how many moles of H2O will be produced if 6.8 moles of O2 reacts completely with CH4?

Answer 1

`6.8 molH_2O`

Step-by-step explanation:

Hello there!

In this case, for this balanced chemical reaction about the combustion of methane, it is possible for us to inspect the 2:2 mole ratio of water to oxygen as given for their coefficients in the balanced chemical reaction.

In such a wat, given 6.8 moles of oxygen, we can easily obtain the produced moles of water by applying the aforementioned mole ratio as shown below:

`6.8molO_2*(2molH_2O)/(2molO_2)\\\\6.8 molH_2O`

Best regards!
