Question

CH 4 + 2O 2 -> CO 2 how many moles of oxygen are necessary to react completely with 5.5 moles of CH^4 please show work asap :(

Answer 1

11 moles of oxygen are necessary to react completely with 5.5 moles of CH₄

Step-by-step explanation:

The balanced reaction is:

CH₄ + 2 O₂ → CO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction) , the following amounts of each compound:

• CH₄: 1 mole
• O₂: 2 moles
• CO₂: 1 mole

Then you can apply the following rule of three: If by stoichiometry 1 mole of CH₄ reacts with 2 moles of O₂, 5.5 moles of CH₄ reacts with how many moles of O₂?

`moles of O_(2) =(5.5 moles of CH_(4)* 2moles of O_(2) )/(1 mole of CH_(4) )`

moles of O₂= 11 moles

11 moles of oxygen are necessary to react completely with 5.5 moles of CH₄
