Limiting reagents/moles help!!?

A student combusts 15 g of methane (CH4) with 50. g of oxygen to form carbon dioxide and water.





1.Write out the balanced chemical reaction.


2. Which reactant is the limiting reagent?


3. How many moles of water will be produced?


4. What mass of carbon dioxide will be produced?


5. After the reaction is completed how many moles of methane will remain? (amount of reactant remaining = initial amount of reactant - amount of reactant consumed by the reaction)


6. After the reaction is completed how many moles of oxygen will remain?





please help me!!

1) CH4 + 2O2 --%26gt; CO2 + 2H2O


2) Methane


3) 1.875 moles
