Study the reaction.CH4 + 2O2 → CO2 + 2H2OIf 4.0 moles of methane (CH4) and 8.0 moles of oxygen (O2) enter this reaction, how many moles of carbon dioxide (CO2) and water (H2O) will be created at the end of the reaction?

Study the reactionCH4 2O2 CO2 2H2OIf 40 moles of methane CH4 and 80 moles of oxygen O2 enter this reaction how many moles of carbon dioxide CO2 and water H2O wi class=

Answer:

4 moles of COâ‚‚ and 8 moles of Hâ‚‚O. Option A is correct

Explanations;

Given the chemical reaction shown below;

[tex]CH_4+2O_2\rightarrow CO_2+2H_2O[/tex]

Since 4.0 moles of methane (CHâ‚„) and 8.0 moles of oxygen (Oâ‚‚) enter this reaction, methane will act as the limiting reactant.

According to stochiometry, 1 mole of methane produces 1 mole of COâ‚‚, hence the moles of COâ‚‚ created at the end of the reaction will also be 4 moles

Also, since 1 mole of methane produces 2 moles of water, the moles of Hâ‚‚O created at the end of the reaction will be 2(4) = 8 moles.
