How many grams of carbon dioxide are produced when 16.0
Kobotan [32]

Mass of CO₂ = 33 g

<h3>Further explanation  </h3>

Complete combustion of Hydrocarbons with Oxygen will be obtained by CO₂ and H₂O compounds.  

If O₂ is insufficient there will be incomplete combustion produced by CO and H and O  

Reaction

CH₄ + 2O₂⇒CO₂ + 2H₂O

mol CH₄ :

\tt =\dfrac{16}{16}=1

mol O₂ :

\tt =\dfrac{48}{32}=1.5

A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients

\tt CH_4:O_2=\dfrac{1}{1}:\dfrac{1.5}{2}=1:0.75

Because O₂ ratio smaller then O₂ becomes the limiting  reactants

So mol CO₂ from limiting reactants

mol CO₂ :

\tt \dfrac{1}{2}\times 1.5=0.75

mass CO₂ :

\tt mass=mol\times MW=0.75\times 44=33~g
