3. If you begin the reaction with 34.6 grams of methane (CH4), how many moles of water
(H20) will be produced?

4. Determine how many grams of oxygen would be necessary for the complete combustion
of 67.9 grams of CH4

5. Determine how many grams of carbon dioxide would be produced from the reaction of
methane with 56.4 grams of oxygen (O2).

6. An inventor is trying to design a new shape of combustion chamber to maximize the heat
transfer in a home furnace. If the inlet valve of the combustion chamber releases 0.24
grams of methane(CH4) each time but only has a chamber large enough to hold 2.43 L of
air at STP in addition to the volume of methane released. Would this have enough oxygen
to be considered safe to use in a home? Air at standard temperature and pressure is
approximately 22.4% oxygen at STP.
