Question

Given the following reaction:

CH4 +202
CO2 + 2H2O
How many moles of CO2, will be produced from 20.0 g of CH4, assuming O2 is available in excess?​

Answer 1

Answer:1.25 moles

Explanation:

Answer 2

1.25 moles of CO₂ is formed from 20.0 g of CH4,.

Step-by-step explanation:

The balanced equation for the combustion of methane produces carbon-di- oxide and water.

CH₄ +20₂ → CO₂ + 2 H₂O

First we need to find the number of moles of methane reacted using the given mass and its molar mass as,

`$ moles of CH_(4) = (mass)/(molar mass)`

`$ moles of methane = ( 20 g)/(16 g/ mol) =1.25 moles`

`$( 1 mol of CO_(2) )/(1 mol of CH_(4) ) * 1.25 mol of CH_(4) = 1.25 mol of CO_(2)`

Thus it is calculated that 1.25 moles of CO₂ is formed from 20.0 g of CH4,.
