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?​

Respuesta :

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

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,

[tex]$ moles of CH_{4} = \frac{mass}{molar mass}[/tex]

[tex]$ moles of methane = \frac{ 20 g}{16 g/ mol} =1.25 moles[/tex]                    

[tex]$\frac{ 1 mol of CO_{2} }{1 mol of CH_{4} } \times 1.25 mol of CH_{4} = 1.25 mol of CO_{2}[/tex]

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

Answer:1.25 moles
