Question

CH4 + 2O2 --> CO2 + 2H2O

If you have 1 mole of CH4 and 6 moles of CO2 how many moles of CO2 and H2O will be produced?​

Answer 1

1 mole of CO2 and 2 mole H2O will be produced in the reaction.

Step-by-step explanation:

N:B: I guess it will be 6 moles of O2 not CO2.

Balanced Equation: CH4 + 2O2 --> CO2 + 2H2O

Given,

1 mole CH4

6 moles of O2

According to Stoichiometry,

In the reaction,

2 mole O2 reacts with 1 mole CH4

1 mole O2 reacts with 1/2 mole CH4

∴6 mole O2 reacts with (1/2)*6 mole CH4

= 3 moles of CH4

But, there is only 1 mole CH4 provided. So CH4 is the limiting reagent.

Now,

According to Stoichiometry,

In the reaction,

1 mole CH4 produces 2 moles of H2O

Again,

According to Stoichiometry,

In the reaction,

1 mole CH4 produces 1 mole CO2

So, 1 mole of CO2 and 2 mole H2O will be produced in the reaction.

N:B:[Doing calculation with limiting reagent in problems like these gives you the most accurate answer].
