During combustion, methane yields carbon dioxide and water. The unbalanced equation for this reaction is:

CH4(g) + O2(g) CO2(g) + H2O(l)

What will the mole ratios for the balanced equation be? (What coefficients are needed in order to balance this equation?)

A. 1 : 1 : 2 : 1

B. 5 : 4 : 3 : 6

C. 1 : 2 : 1 : 2

D. 1 : 1 : 1 : 2

Respuesta :

naads
ans C
you should have the same number of H and O as well on both sides

1 : 2 : 1 : 2  will the mole ratios for the balanced equation. Hence, option C is correct.

What is combustion?

Combustion is a scientific term for burning. We all know about burning, but  burning is actually a chemical reaction.

Combustion is a chemical process where any fuel has a reaction with air to produce heat energy.

When this heat energy release it will also produce light in the form of a flame.

This is the visible part of the reaction (flames). The general exothermic reaction of combustion.

General form of combustion:

Hydrocarbon + Oxygen → Carbon Dioxide + Water + Heat Energy

Chemical Equation:

CH₄(g) + O₂(g) →  CO₂(g) + H₂O(l) (unbalanced  equation)

CH₄(g) + 2O₂(g) →  CO₂(g) + 2H₂O(l) (balanced  equation)

In combustion a require mole of compound is 1 mole of methane burn in air (oxygen) to produce 1mole of carbon di-oxide and 2 mole of water.

1 : 2 : 1 : 2  will the mole ratios for the balanced equation. Hence, option C is correct.
