Suppose 8.00 g of CH4 is allowed to burn in the presence of 6.00 g of oxygen. How much (in grams) CH4, O2, CO2, and H2O remain after the reaction is complete?
All you chemistry freaks out there solve this one for me, and show all your working

oh well.. let's see if I remember any of my A level Chemistry..
Hydrogen has weight 1, Carbon 4, Oxygen 2
Methane burns in Oxygen into Carbon Dioxide and water.
ch4 + 2 x(o2) = co2 + 2 x(h2o)
Therefore, if my logic and memory is correct 6g of Oxygen will react with 6g of methane to produce 6g of carbon dioxide and 6g of water, leaving 2g of Methane unreacted.

But then again, I could be totally wrong - I am an actuary by profession and don't deal with chemicals at all!!
