Given the balanced reaction CH4 + 2O2 - > CO2 + 2H2O2 How many moles of oxygen are needed to completely react with 1 mole of CH4?

2 moles

4 moles

1 mole

0.5 moles

Answer: 2.0 moles of oxygen are needed to completely react with 1.0 mole of CH4 as shown in the balanced equation.

Explanation:

Stoichiometry is a fundamental tool and skill to determine the relative quantities that the chemicals react with. it determines the quantity of one substance to a quantity of another substance or substances. Stoichiometry is relating of one chemical substance to another using a balanced chemical reaction is called stoichiometry. Also, it is very important to predict what will occur and how much is produced through knowing the coefficients of moles of reactants and products.

Mole s defined as the mass of the substance divided by its molar mass.

As shown from the balanced equation every mole of methane (CH4) needs to react with 2.0 moles of oxygen (O2) to produce 1.0 mole of carbon dioxide (CO2) and 2.0 moles of hydrogen peroxide (H2O2).
