CH4 + 2O2=CO2+2H2O. how many moles of O2 will be needed to produce 5.0 moles of CO2 from the correctly balanced reaction?​

10 moles of O2

Explanation:

Balanced Equation:

CH4 + 2O2=CO2+2H2O

Now,

According to Stoichiometry,

In the reaction,

           1 mole CO2 is produced by 2 moles of O2

∴5 moles of CO2 is produced by (2 X 5) moles of O2

                                                       = 10 moles of O2

Therefore, to produce 5 moles of CO2, 10 moles of Oxygen is needed.

the answer is alpha particles hope i you

the answer is a. co2, this would be colder than the : )
